PCS(8) System Administration Utilities PCS(8) NAME pcs - pacemaker/corosync configuration system SYNOPSIS pcs [-f file] [-h] [commands]... DESCRIPTION Control and configure pacemaker and corosync. OPTIONS -h, --help Display usage and exit. -f file Perform actions on file instead of active CIB. --debug Print all network traffic and external commands run. --version Print pcs version information. Commands: cluster Configure cluster options and nodes. resource Manage cluster resources. stonith Configure fence devices. constraint Set resource constraints. property Set pacemaker properties. acl Set pacemaker access control lists. qdevice Manage quorum device provider on the local host. quorum Manage cluster quorum settings. status View cluster status. config View and manage cluster configuration. pcsd Manage pcs daemon. node Manage cluster nodes. alert Manage pacemaker alerts. resource [show [resource id]] [--full] [--groups] Show all currently configured resources or if a resource is specified show the options for the configured resource. If --full is specified all configured resource options will be dis‐ played. If --groups is specified, only show groups (and their resources). list [<standard|provider|type>] [--nodesc] Show list of all available resources, optionally filtered by specified type, standard or provider. If --nodesc is used then descriptions of resources are not printed. describe <standard:provider:type|type> Show options for the specified resource. create <resource id> <standard:provider:type|type> [resource options] [op <operation action> <operation options> [<operation action> <opera‐ tion options>]...] [meta <meta options>...] [--clone <clone options> | --master <master options> | --group <group id> [--before <resource id> | --after <resource id>]] [--disabled] [--wait[=n]] Create specified resource. If --clone is used a clone resource is created. If --master is specified a master/slave resource is created. If --group is specified the resource is added to the group named. You can use --before or --after to specify the position of the added resource relatively to some resource already existing in the group. If --disabled is specified the resource is not started automatically. If --wait is specified, pcs will wait up to 'n' seconds for the resource to start and then return 0 if the resource is started, or 1 if the resource has not yet started. If 'n' is not specified it defaults to 60 minutes. Example: Create a new resource called 'VirtualIP' with IP address 192.168.0.99, netmask of 32, monitored everything 30 seconds, on eth2: pcs resource create VirtualIP ocf:heart‐ beat:IPaddr2 ip=192.168.0.99 cidr_netmask=32 nic=eth2 op monitor interval=30s delete <resource id|group id|master id|clone id> Deletes the resource, group, master or clone (and all resources within the group/master/clone). enable <resource id> [--wait[=n]] Allow the cluster to start the resource. Depending on the rest of the configuration (constraints, options, failures, etc), the resource may remain stopped. If --wait is specified, pcs will wait up to 'n' seconds for the resource to start and then return 0 if the resource is started, or 1 if the resource has not yet started. If 'n' is not specified it defaults to 60 minutes. disable <resource id> [--wait[=n]] Attempt to stop the resource if it is running and forbid the cluster from starting it again. Depending on the rest of the configuration (constraints, options, failures, etc), the resource may remain started. If --wait is specified, pcs will wait up to 'n' seconds for the resource to stop and then return 0 if the resource is stopped or 1 if the resource has not stopped. If 'n' is not specified it defaults to 60 minutes. restart <resource id> [node] [--wait=n] Restart the resource specified. If a node is specified and if the resource is a clone or master/slave it will be restarted only on the node specified. If --wait is specified, then we will wait up to 'n' seconds for the resource to be restarted and return 0 if the restart was successful or 1 if it was not. debug-start <resource id> [--full] This command will force the specified resource to start on this node ignoring the cluster recommendations and print the output from starting the resource. Using --full will give more detailed output. This is mainly used for debugging resources that fail to start. debug-stop <resource id> [--full] This command will force the specified resource to stop on this node ignoring the cluster recommendations and print the output from stopping the resource. Using --full will give more detailed output. This is mainly used for debugging resources that fail to stop. debug-promote <resource id> [--full] This command will force the specified resource to be promoted on this node ignoring the cluster recommendations and print the output from promoting the resource. Using --full will give more detailed output. This is mainly used for debugging resources that fail to promote. debug-demote <resource id> [--full] This command will force the specified resource to be demoted on this node ignoring the cluster recommendations and print the output from demoting the resource. Using --full will give more detailed output. This is mainly used for debugging resources that fail to demote. debug-monitor <resource id> [--full] This command will force the specified resource to be moniored on this node ignoring the cluster recommendations and print the output from monitoring the resource. Using --full will give more detailed output. This is mainly used for debugging resources that fail to be monitored. move <resource id> [destination node] [--master] [lifetime=<lifetime>] [--wait[=n]] Move the resource off the node it is currently running on by creating a -INFINITY location constraint to ban the node. If destination node is specified the resource will be moved to that node by creating an INFINITY location constraint to prefer the destination node. If --master is used the scope of the command is limited to the master role and you must use the master id (instead of the resource id). If lifetime is specified then the constraint will expire after that time, otherwise it defaults to infinity and the constraint can be cleared manually with 'pcs resource clear' or 'pcs constraint delete'. If --wait is speci‐ fied, pcs will wait up to 'n' seconds for the resource to move and then return 0 on success or 1 on error. If 'n' is not spec‐ ified it defaults to 60 minutes. If you want the resource to preferably avoid running on some nodes but be able to failover to them use 'pcs location avoids'. ban <resource id> [node] [--master] [lifetime=<lifetime>] [--wait[=n]] Prevent the resource id specified from running on the node (or on the current node it is running on if no node is specified) by creating a -INFINITY location constraint. If --master is used the scope of the command is limited to the master role and you must use the master id (instead of the resource id). If life‐ time is specified then the constraint will expire after that time, otherwise it defaults to infinity and the constraint can be cleared manually with 'pcs resource clear' or 'pcs constraint delete'. If --wait is specified, pcs will wait up to 'n' sec‐ onds for the resource to move and then return 0 on success or 1 on error. If 'n' is not specified it defaults to 60 minutes. If you want the resource to preferably avoid running on some nodes but be able to failover to them use 'pcs location avoids'. clear <resource id> [node] [--master] [--wait[=n]] Remove constraints created by move and/or ban on the specified resource (and node if specified). If --master is used the scope of the command is limited to the master role and you must use the master id (instead of the resource id). If --wait is speci‐ fied, pcs will wait up to 'n' seconds for the operation to fin‐ ish (including starting and/or moving resources if appropriate) and then return 0 on success or 1 on error. If 'n' is not spec‐ ified it defaults to 60 minutes. standards List available resource agent standards supported by this installation (OCF, LSB, etc.). providers List available OCF resource agent providers. agents [standard[:provider]] List available agents optionally filtered by standard and provider. update <resource id> [resource options] [op [<operation action> <opera‐ tion options>]...] [meta <meta operations>...] [--wait[=n]] Add/Change options to specified resource, clone or multi-state resource. If an operation (op) is specified it will update the first found operation with the same action on the specified resource, if no operation with that action exists then a new operation will be created. (WARNING: all existing options on the updated operation will be reset if not specified.) If you want to create multiple monitor operations you should use the 'op add' & 'op remove' commands. If --wait is specified, pcs will wait up to 'n' seconds for the changes to take effect and then return 0 if the changes have been processed or 1 otherwise. If 'n' is not specified it defaults to 60 minutes. op add <resource id> <operation action> [operation properties] Add operation for specified resource. op remove <resource id> <operation action> [<operation properties>...] Remove specified operation (note: you must specify the exact operation properties to properly remove an existing operation). op remove <operation id> Remove the specified operation id. op defaults [options] Set default values for operations, if no options are passed, lists currently configured defaults. meta <resource id | group id | master id | clone id> <meta options> [--wait[=n]] Add specified options to the specified resource, group, mas‐ ter/slave or clone. Meta options should be in the format of name=value, options may be removed by setting an option without a value. If --wait is specified, pcs will wait up to 'n' sec‐ onds for the changes to take effect and then return 0 if the changes have been processed or 1 otherwise. If 'n' is not spec‐ ified it defaults to 60 minutes. Example: pcs resource meta TestResource failure-timeout=50 stickiness= group add <group id> <resource id> [resource id] ... [resource id] [--before <resource id> | --after <resource id>] [--wait[=n]] Add the specified resource to the group, creating the group if it does not exist. If the resource is present in another group it is moved to the new group. You can use --before or --after to specify the position of the added resources relatively to some resource already existing in the group. If --wait is spec‐ ified, pcs will wait up to 'n' seconds for the operation to fin‐ ish (including moving resources if appropriate) and then return 0 on success or 1 on error. If 'n' is not specified it defaults to 60 minutes. group remove <group id> <resource id> [resource id] ... [resource id] [--wait[=n]] Remove the specified resource(s) from the group, removing the group if it no resources remain. If --wait is specified, pcs will wait up to 'n' seconds for the operation to finish (includ‐ ing moving resources if appropriate) and then return 0 on suc‐ cess or 1 on error. If 'n' is not specified it defaults to 60 minutes. ungroup <group id> [resource id] ... [resource id] [--wait[=n]] Remove the group (note: this does not remove any resources from the cluster) or if resources are specified, remove the specified resources from the group. If --wait is specified, pcs will wait up to 'n' seconds for the operation to finish (including moving resources if appropriate) and the return 0 on success or 1 on error. If 'n' is not specified it defaults to 60 minutes. clone <resource id | group id> [clone options]... [--wait[=n]] Setup up the specified resource or group as a clone. If --wait is specified, pcs will wait up to 'n' seconds for the operation to finish (including starting clone instances if appropriate) and then return 0 on success or 1 on error. If 'n' is not spec‐ ified it defaults to 60 minutes. unclone <resource id | group id> [--wait[=n]] Remove the clone which contains the specified group or resource (the resource or group will not be removed). If --wait is spec‐ ified, pcs will wait up to 'n' seconds for the operation to fin‐ ish (including stopping clone instances if appropriate) and then return 0 on success or 1 on error. If 'n' is not specified it defaults to 60 minutes. master [<master/slave id>] <resource id | group id> [options] [--wait[=n]] Configure a resource or group as a multi-state (master/slave) resource. If --wait is specified, pcs will wait up to 'n' sec‐ onds for the operation to finish (including starting and promot‐ ing resource instances if appropriate) and then return 0 on suc‐ cess or 1 on error. If 'n' is not specified it defaults to 60 minutes. Note: to remove a master you must remove the resource/group it contains. manage <resource id> ... [resource n] Set resources listed to managed mode (default). unmanage <resource id> ... [resource n] Set resources listed to unmanaged mode. defaults [options] Set default values for resources, if no options are passed, lists currently configured defaults. cleanup [<resource id>] [--node <node>] Cleans up the resource in the lrmd (useful to reset the resource status and failcount). This tells the cluster to forget the operation history of a resource and re-detect its current state. This can be useful to purge knowledge of past failures that have since been resolved. If a resource id is not specified then all resources/stonith devices will be cleaned up. If a node is not specified then resources on all nodes will be cleaned up. failcount show <resource id> [node] Show current failcount for specified resource from all nodes or only on specified node. failcount reset <resource id> [node] Reset failcount for specified resource on all nodes or only on specified node. This tells the cluster to forget how many times a resource has failed in the past. This may allow the resource to be started or moved to a more preferred location. relocate dry-run [resource1] [resource2] ... The same as 'relocate run' but has no effect on the cluster. relocate run [resource1] [resource2] ... Relocate specified resources to their preferred nodes. If no resources are specified, relocate all resources. This command calculates the preferred node for each resource while ignoring resource stickiness. Then it creates location constraints which will cause the resources to move to their preferred nodes. Once the resources have been moved the constraints are deleted auto‐ matically. Note that the preferred node is calculated based on current cluster status, constraints, location of resources and other settings and thus it might change over time. relocate show Display current status of resources and their optimal node ignoring resource stickiness. relocate clear Remove all constraints created by the 'relocate run' command. utilization [<resource id> [<name>=<value> ...]] Add specified utilization options to specified resource. If resource is not specified, shows utilization of all resources. If utilization options are not specified, shows utilization of specified resource. Utilization option should be in format name=value, value has to be integer. Options may be removed by setting an option without a value. Example: pcs resource uti‐ lization TestResource cpu= ram=20 cluster auth [node] [...] [-u username] [-p password] [--force] [--local] Authenticate pcs to pcsd on nodes specified, or on all nodes configured in corosync.conf if no nodes are specified (autho‐ rization tokens are stored in ~/.pcs/tokens or /var/lib/pcsd/tokens for root). By default all nodes are also authenticated to each other, using --local only authenticates the local node (and does not authenticate the remote nodes with each other). Using --force forces re-authentication to occur. setup [--start [--wait[=<n>]]] [--local] [--enable] --name <cluster name> <node1[,node1-altaddr]> [<node2[,node2-altaddr]>] [...] [--trans‐ port udpu|udp] [--rrpmode active|passive] [--addr0 <addr/net> [[[--mcast0 <address>] [--mcastport0 <port>] [--ttl0 <ttl>]] | [--broadcast0]] [--addr1 <addr/net> [[[--mcast1 <address>] [--mcast‐ port1 <port>] [--ttl1 <ttl>]] | [--broadcast1]]]] [--wait_for_all=<0|1>] [--auto_tie_breaker=<0|1>] [--last_man_stand‐ ing=<0|1> [--last_man_standing_window=<time in ms>]] [--ipv6] [--token <timeout>] [--token_coefficient <timeout>] [--join <timeout>] [--con‐ sensus <timeout>] [--miss_count_const <count>] [--fail_recv_const <failures>] Configure corosync and sync configuration out to listed nodes. --local will only perform changes on the local node, --start will also start the cluster on the specified nodes, --wait will wait up to 'n' seconds for the nodes to start, --enable will enable corosync and pacemaker on node startup, --transport allows specification of corosync transport (default: udpu; udp for CMAN clusters), --rrpmode allows you to set the RRP mode of the system. Currently only 'passive' is supported or tested (using 'active' is not recommended). The --wait_for_all, --auto_tie_breaker, --last_man_standing, --last_man_stand‐ ing_window options are all documented in corosync's votequo‐ rum(5) man page. These options are not supported on CMAN clus‐ ters. --ipv6 will configure corosync to use ipv6 (instead of ipv4). This option is not supported on CMAN clusters. --token <timeout> sets time in milliseconds until a token loss is declared after not receiving a token (default 1000 ms) --token_coefficient <timeout> sets time in milliseconds used for clusters with at least 3 nodes as a coefficient for real token timeout calculation (token + (number_of_nodes - 2) * token_coef‐ ficient) (default 650 ms) This option is not supported on CMAN clusters. --join <timeout> sets time in milliseconds to wait for join mes‐ sages (default 50 ms) --consensus <timeout> sets time in milliseconds to wait for con‐ sensus to be achieved before starting a new round of membership configuration (default 1200 ms) --miss_count_const <count> sets the maximum number of times on receipt of a token a message is checked for retransmission before a retransmission occurs (default 5 messages) --fail_recv_const <failures> specifies how many rotations of the token without receiving any messages when messages should be received may occur before a new configuration is formed (default 2500 failures) Configuring Redundant Ring Protocol (RRP) When using udpu specifying nodes, specify the ring 0 address first followed by a ',' and then the ring 1 address. Example: pcs cluster setup --name cname nodeA-0,nodeA-1 nodeB-0,nodeB-1 When using udp, using --addr0 and --addr1 will allow you to con‐ figure rrp mode for corosync. It's recommended to use a network (instead of IP address) for --addr0 and --addr1 so the same corosync.conf file can be used around the cluster. --mcast0 defaults to 239.255.1.1 and --mcast1 defaults to 239.255.2.1, --mcastport0/1 default to 5405 and ttl defaults to 1. If --broadcast is specified, --mcast0/1, --mcastport0/1 & --ttl0/1 are ignored. start [--all] [node] [...] [--wait[=<n>]] Start corosync & pacemaker on specified node(s), if a node is not specified then corosync & pacemaker are started on the local node. If --all is specified then corosync & pacemaker are started on all nodes. If --wait is specified, wait up to 'n' seconds for nodes to start. stop [--all] [node] [...] Stop corosync & pacemaker on specified node(s), if a node is not specified then corosync & pacemaker are stopped on the local node. If --all is specified then corosync & pacemaker are stopped on all nodes. kill Force corosync and pacemaker daemons to stop on the local node (performs kill -9). Note that init system (e.g. systemd) can detect that cluster is not running and start it again. If you want to stop cluster on a node, run pcs cluster stop on that node. enable [--all] [node] [...] Configure corosync & pacemaker to run on node boot on specified node(s), if node is not specified then corosync & pacemaker are enabled on the local node. If --all is specified then corosync & pacemaker are enabled on all nodes. disable [--all] [node] [...] Configure corosync & pacemaker to not run on node boot on speci‐ fied node(s), if node is not specified then corosync & pacemaker are disabled on the local node. If --all is specified then corosync & pacemaker are disabled on all nodes. Note: this is the default after installation. remote-node add <hostname> <resource id> [options] Enables the specified resource as a remote-node resource on the specified hostname (hostname should be the same as 'uname -n'). remote-node remove <hostname> Disables any resources configured to be remote-node resource on the specified hostname (hostname should be the same as 'uname -n'). status View current cluster status (an alias of 'pcs status cluster'). pcsd-status [node] [...] Get current status of pcsd on nodes specified, or on all nodes configured in corosync.conf if no nodes are specified. sync Sync corosync configuration to all nodes found from current corosync.conf file (cluster.conf on systems running Corosync 1.x). cib [filename] [scope=<scope> | --config] Get the raw xml from the CIB (Cluster Information Base). If a filename is provided, we save the CIB to that file, otherwise the CIB is printed. Specify scope to get a specific section of the CIB. Valid values of the scope are: configuration, nodes, resources, constraints, crm_config, rsc_defaults, op_defaults, status. --config is the same as scope=configuration. Do not specify a scope if you want to edit the saved CIB using pcs (pcs -f <command>). cib-push <filename> [scope=<scope> | --config] [--wait[=<n>]] Push the raw xml from <filename> to the CIB (Cluster Information Base). You can obtain the CIB by running the 'pcs cluster cib' command, which is recommended first step when you want to per‐ form desired modifications (pcs -f <command>) for the one-off push. Specify scope to push a specific section of the CIB. Valid values of the scope are: configuration, nodes, resources, constraints, crm_config, rsc_defaults, op_defaults. --config is the same as scope=configuration. Use of --config is recom‐ mended. Do not specify a scope if you need to push the whole CIB or be warned in the case of outdated CIB. If --wait is specified wait up to 'n' seconds for changes to be applied. WARNING: the selected scope of the CIB will be overwritten by the current content of the specified file. cib-upgrade Upgrade the CIB to conform to the latest version of the document schema. edit [scope=<scope> | --config] Edit the cib in the editor specified by the $EDITOR environment variable and push out any changes upon saving. Specify scope to edit a specific section of the CIB. Valid values of the scope are: configuration, nodes, resources, constraints, crm_config, rsc_defaults, op_defaults. --config is the same as scope=con‐ figuration. Use of --config is recommended. Do not specify a scope if you need to edit the whole CIB or be warned in the case of outdated CIB. node add <node[,node-altaddr]> [--start [--wait[=<n>]]] [--enable] Add the node to corosync.conf and corosync on all nodes in the cluster and sync the new corosync.conf to the new node. If --start is specified also start corosync/pacemaker on the new node, if --wait is sepcified wait up to 'n' seconds for the new node to start. If --enable is specified enable corosync/pace‐ maker on new node. When using Redundant Ring Protocol (RRP) with udpu transport, specify the ring 0 address first followed by a ',' and then the ring 1 address. node remove <node> Shutdown specified node and remove it from pacemaker and corosync on all other nodes in the cluster. uidgid List the current configured uids and gids of users allowed to connect to corosync. uidgid add [uid=<uid>] [gid=<gid>] Add the specified uid and/or gid to the list of users/groups allowed to connect to corosync. uidgid rm [uid=<uid>] [gid=<gid>] Remove the specified uid and/or gid from the list of users/groups allowed to connect to corosync. corosync [node] Get the corosync.conf from the specified node or from the cur‐ rent node if node not specified. reload corosync Reload the corosync configuration on the current node. destroy [--all] Permanently destroy the cluster on the current node, killing all corosync/pacemaker processes removing all cib files and the corosync.conf file. Using --all will attempt to destroy the cluster on all nodes configure in the corosync.conf file. WARN‐ ING: This command permantly removes any cluster configuration that has been created. It is recommended to run 'pcs cluster stop' before destroying the cluster. verify [-V] [filename] Checks the pacemaker configuration (cib) for syntax and common conceptual errors. If no filename is specified the check is performed on the currently running cluster. If -V is used more verbose output will be printed. report [--from "YYYY-M-D H:M:S" [--to "YYYY-M-D" H:M:S"]] dest Create a tarball containing everything needed when reporting cluster problems. If --from and --to are not used, the report will include the past 24 hours. stonith [show [stonith id]] [--full] Show all currently configured stonith devices or if a stonith id is specified show the options for the configured stonith device. If --full is specified all configured stonith options will be displayed. list [filter] [--nodesc] Show list of all available stonith agents (if filter is provided then only stonith agents matching the filter will be shown). If --nodesc is used then descriptions of stonith agents are not printed. describe <stonith agent> Show options for specified stonith agent. create <stonith id> <stonith device type> [stonith device options] [op <operation action> <operation options> [<operation action> <operation options>]...] [meta <meta options>...] Create stonith device with specified type and options. update <stonith id> [stonith device options] Add/Change options to specified stonith id. delete <stonith id> Remove stonith id from configuration. cleanup [<stonith id>] [--node <node>] Cleans up the stonith device in the lrmd (useful to reset the status and failcount). This tells the cluster to forget the operation history of a stonith device and re-detect its current state. This can be useful to purge knowledge of past failures that have since been resolved. If a stonith id is not specified then all resources/stonith devices will be cleaned up. If a node is not specified then resources on all nodes will be cleaned up. level Lists all of the fencing levels currently configured. level add <level> <node> <devices> Add the fencing level for the specified node with a comma sepa‐ rated list of devices (stonith ids) to attempt for that node at that level. Fence levels are attempted in numerical order (starting with 1) if a level succeeds (meaning all devices are successfully fenced in that level) then no other levels are tried, and the node is considered fenced. level remove <level> [node id] [stonith id] ... [stonith id] Removes the fence level for the level, node and/or devices spec‐ ified. If no nodes or devices are specified then the fence level is removed. level clear [node|stonith id(s)] Clears the fence levels on the node (or stonith id) specified or clears all fence levels if a node/stonith id is not specified. If more than one stonith id is specified they must be separated by a comma and no spaces. Example: pcs stonith level clear dev_a,dev_b level verify Verifies all fence devices and nodes specified in fence levels exist. fence <node> [--off] Fence the node specified (if --off is specified, use the 'off' API call to stonith which will turn the node off instead of rebooting it). confirm <node> [--force] Confirm that the host specified is currently down. This command should ONLY be used when the node specified has already been confirmed to be powered off and to have no access to shared resources. WARNING: If this node is not actually powered off or it does have access to shared resources, data corruption/cluster failure can occur. To prevent accidental running of this command, --force or interactive user response is required in order to proceed. sbd enable [--watchdog=<path>[@<node>]] ... [<SBD_OPTION>=<value>] ... Enable SBD in cluster. Default path for watchdog device is /dev/watchdog. Allowed SBD options: SBD_WATCHDOG_TIMEOUT (default: 5), SBD_DELAY_START (default: no) and SBD_STARTMODE (default: clean). WARNING: Cluster has to be restarted in order to apply these changes. Example of enabling SBD in cluster with watchdogs on node1 will be /dev/watchdog2, on node2 /dev/watchdog1, /dev/watchdog0 on all other nodes and watchdog timeout will bet set to 10 seconds: pcs stonith sbd enable --watchdog=/dev/watchdog2@node1 --watch‐ dog=/dev/watchdog1@node2 --watchdog=/dev/watchdog0 SBD_WATCH‐ DOG_TIMEOUT=10 sbd disable Disable SBD in cluster. WARNING: Cluster has to be restarted in order to apply these changes. sbd status Show status of SBD services in cluster. sbd config Show SBD configuration in cluster. acl [show] List all current access control lists. enable Enable access control lists. disable Disable access control lists. role create <role id> [description=<description>] [((read | write | deny) (xpath <query> | id <id>))...] Create a role with the id and (optional) description specified. Each role can also have an unlimited number of permissions (read/write/deny) applied to either an xpath query or the id of a specific element in the cib. role delete <role id> Delete the role specified and remove it from any users/groups it was assigned to. role assign <role id> [to] <username/group> Assign a role to a user or group already created with 'pcs acl user/group create'. role unassign <role id> [from] <username/group> Remove a role from the specified user. user create <username> <role id> [<role id>]... Create an ACL for the user specified and assign roles to the user. user delete <username> Remove the user specified (and roles assigned will be unassigned for the specified user). group create <group> <role id> [<role id>]... Create an ACL for the group specified and assign roles to the group. group delete <group> Remove the group specified (and roles assigned will be unas‐ signed for the specified group). permission add <role id> ((read | write | deny) (xpath <query> | id <id>))... Add the listed permissions to the role specified. permission delete <permission id> Remove the permission id specified (permission id's are listed in parenthesis after permissions in 'pcs acl' output). property [list|show [<property> | --all | --defaults]] | [--all | --defaults] List property settings (default: lists configured properties). If --defaults is specified will show all property defaults, if --all is specified, current configured properties will be shown with unset properties and their defaults. Run 'man pengine' and 'man crmd' to get a description of the properties. set [--force | --node <nodename>] <property>=[<value>] [<prop‐ erty>=[<value>] ...] Set specific pacemaker properties (if the value is blank then the property is removed from the configuration). If a property is not recognized by pcs the property will not be created unless the --force is used. If --node is used a node attribute is set on the specified node. Run 'man pengine' and 'man crmd' to get a description of the properties. unset [--node <nodename>] <property> Remove property from configuration (or remove attribute from specified node if --node is used). Run 'man pengine' and 'man crmd' to get a description of the properties. constraint [list|show] --full List all current location, order and colocation constraints, if --full is specified also list the constraint ids. location <resource id> prefers <node[=score]>... Create a location constraint on a resource to prefer the speci‐ fied node and score (default score: INFINITY). location <resource id> avoids <node[=score]>... Create a location constraint on a resource to avoid the speci‐ fied node and score (default score: INFINITY). location <resource id> rule [id=<rule id>] [resource-discov‐ ery=<option>] [role=master|slave] [constraint-id=<id>] [score=<score>|score-attribute=<attribute>] <expression> Creates a location rule on the specified resource where the expression looks like one of the following: defined|not_defined <attribute> <attribute> lt|gt|lte|gte|eq|ne [string|integer|version] <value> date gt|lt <date> date in_range <date> to <date> date in_range <date> to duration <duration options>... date-spec <date spec options>... <expression> and|or <expression> ( <expression> ) where duration options and date spec options are: hours, month‐ days, weekdays, yeardays, months, weeks, years, weekyears, moon. If score is omitted it defaults to INFINITY. If id is omitted one is generated from the resource id. If resource-discovery is omitted it defaults to 'always'. location [show [resources|nodes [node id|resource id]...] [--full]] List all the current location constraints, if 'resources' is specified location constraints are displayed per resource (default), if 'nodes' is specified location constraints are dis‐ played per node. If specific nodes or resources are specified then we only show information about them. If --full is speci‐ fied show the internal constraint id's as well. location add <id> <resource id> <node> <score> [resource-discov‐ ery=<option>] Add a location constraint with the appropriate id, resource id, node name and score. (For more advanced pacemaker usage.) location remove <id> [<resource id> <node> <score>] Remove a location constraint with the appropriate id, resource id, node name and score. (For more advanced pacemaker usage.) order [show] [--full] List all current ordering constraints (if --full is specified show the internal constraint id's as well). order [action] <resource id> then [action] <resource id> [options] Add an ordering constraint specifying actions (start, stop, pro‐ mote, demote) and if no action is specified the default action will be start. Available options are kind=Optional/Manda‐ tory/Serialize, symmetrical=true/false, require-all=true/false and id=<constraint-id>. order set <resource1> [resourceN]... [options] [set <resourceX> ... [options]] [setoptions [constraint_options]] Create an ordered set of resources. Available options are sequential=true/false, require-all=true/false, action=start/pro‐ mote/demote/stop and role=Stopped/Started/Master/Slave. Avail‐ able constraint_options are id=<constraint-id>, kind=Optional/Mandatory/Serialize and symmetrical=true/false. order remove <resource1> [resourceN]... Remove resource from any ordering constraint colocation [show] [--full] List all current colocation constraints (if --full is specified show the internal constraint id's as well). colocation add [master|slave] <source resource id> with [master|slave] <target resource id> [score] [options] [id=constraint-id] Request <source resource> to run on the same node where pace‐ maker has determined <target resource> should run. Positive values of score mean the resources should be run on the same node, negative values mean the resources should not be run on the same node. Specifying 'INFINITY' (or '-INFINITY') for the score forces <source resource> to run (or not run) with <target resource> (score defaults to "INFINITY"). A role can be master or slave (if no role is specified, it defaults to 'started'). colocation set <resource1> [resourceN]... [options] [set <resourceX> ... [options]] [setoptions [constraint_options]] Create a colocation constraint with a resource set. Available options are sequential=true/false, require-all=true/false, action=start/promote/demote/stop and role=Stopped/Started/Mas‐ ter/Slave.

Available option is loss-policy=fence/stop/freeze/demote. A role can be master, slave, started or stopped. ticket set <resource1> [resourceN]... [options] [set <resourceX> ... [options]] [setoptions [constraint_options]] Create a ticket constraint with a resource set. Available options are sequential=true/false, require-all=true/false, action=start/promote/demote/stop and role=Stopped/Started/Mas‐ ter/Slave. Required constraint option is ticket=<ticket>. Optional constraint options are id=<constraint-id> and loss-pol‐ icy=fence/stop/freeze/demote. remove [constraint id]...

List constraints referencing specified resource. rule add <constraint id> [id=<rule id>] [role=master|slave] [score=<score>|score-attribute=<attribute>] <expression> Add a rule to a constraint where the expression looks like one of the following: defined|not_defined <attribute> <attribute> lt|gt|lte|gte|eq|ne [string|integer|version] <value> date gt|lt <date> date in_range <date> to <date> date in_range <date> to duration <duration options>... date-spec <date spec options>... <expression> and|or <expression> ( <expression> ) where duration options and date spec options are: hours, month‐ days, weekdays, yeardays, months, weeks, years, weekyears, moon If score is ommited it defaults to INFINITY. If id is ommited one is generated from the constraint id. rule remove <rule id> Remove a rule if a rule id is specified, if rule is last rule in its constraint, the constraint will be removed. qdevice status <device model> [--full] [<cluster name>] Show runtime status of specified model of quorum device provider. Using --full will give more detailed output. If <cluster name> is specified, only information about the speci‐ fied cluster will be displayed. setup model <device model> [--enable] [--start] Configure specified model of quorum device provider. Quorum device then can be added to clusters by running "pcs quorum device add" command in a cluster. --start will also start the provider. --enable will configure the provider to start on boot. destroy <device model> Disable and stop specified model of quorum device provider and delete its configuration files. start <device model> Start specified model of quorum device provider. stop <device model> Stop specified model of quorum device provider. kill <device model> Force specified model of quorum device provider to stop (per‐ forms kill -9). Note that init system (e.g. systemd) can detect that the qdevice is not running and start it again. If you want to stop the qdevice, run "pcs qdevice stop" command. enable <device model> Configure specified model of quorum device provider to start on boot. disable <device model> Configure specified model of quorum device provider to not start on boot. quorum config Show quorum configuration. status Show quorum runtime status. device add [<generic options>] model <device model> [<model options>] Add a quorum device to the cluster. Quorum device needs to be created first by "pcs qdevice setup" command. It is not possi‐ ble to use more than one quorum device in a cluster simultane‐ ously. Generic options, model and model options are all docu‐ mented in corosync's corosync-qdevice(8) man page. device remove Remove a quorum device from the cluster. device status [--full] Show quorum device runtime status. Using --full will give more detailed output. device update [<generic options>] [model <model options>] Add/Change quorum device options. Generic options and model options are all documented in corosync's corosync-qdevice(8) man page. Requires the cluster to be stopped. WARNING: If you want to change "host" option of qdevice model net, use "pcs quorum device remove" and "pcs quorum device add" commands to set up configuration properly unless old and new host is the same machine. expected-votes <votes> Set expected votes in the live cluster to specified value. This only affects the live cluster, not changes any configuration files. unblock [--force] Cancel waiting for all nodes when establishing quorum. Useful in situations where you know the cluster is inquorate, but you are confident that the cluster should proceed with resource man‐ agement regardless. This command should ONLY be used when nodes which the cluster is waiting for have been confirmed to be pow‐ ered off and to have no access to shared resources. WARNING: If the nodes are not actually powered off or they do have access to shared resources, data corruption/cluster failure can occur. To prevent accidental running of this command, --force or interactive user response is required in order to proceed. update [auto_tie_breaker=[0|1]] [last_man_standing=[0|1]] [last_man_standing_window=[<time in ms>]] [wait_for_all=[0|1]] Add/Change quorum options. At least one option must be speci‐ fied. Options are documented in corosync's votequorum(5) man page. Requires the cluster to be stopped. status [status] [--full | --hide-inactive] View all information about the cluster and resources (--full provides more details, --hide-inactive hides inactive resources). resources View current status of cluster resources. groups View currently configured groups and their resources. cluster View current cluster status. corosync View current membership information as seen by corosync. nodes [corosync|both|config] View current status of nodes from pacemaker. If 'corosync' is specified, print nodes currently configured in corosync, if 'both' is specified, print nodes from both corosync & pacemaker. If 'config' is specified, print nodes from corosync & pacemaker configuration. pcsd [<node>] ... Show the current status of pcsd on the specified nodes. When no nodes are specified, status of all nodes is displayed. xml View xml version of status (output from crm_mon -r -1 -X). config [show] View full cluster configuration. backup [filename] Creates the tarball containing the cluster configuration files. If filename is not specified the standard output will be used. restore [--local] [filename] Restores the cluster configuration files on all nodes from the backup. If filename is not specified the standard input will be used. If --local is specified only the files on the current node will be restored. checkpoint List all available configuration checkpoints. checkpoint view <checkpoint_number> Show specified configuration checkpoint. checkpoint restore <checkpoint_number> Restore cluster configuration to specified checkpoint. import-cman output=<filename> [input=<filename>] [--interactive] [out‐ put-format=corosync.conf|cluster.conf] Converts CMAN cluster configuration to Pacemaker cluster config‐ uration. Converted configuration will be saved to 'output' file. To send the configuration to the cluster nodes the 'pcs config restore' command can be used. If --interactive is speci‐ fied you will be prompted to solve incompatibilities manually. If no input is specified /etc/cluster/cluster.conf will be used. You can force to create output containing either cluster.conf or corosync.conf using the output-format option. import-cman output=<filename> [input=<filename>] [--interactive] out‐ put-format=pcs-commands|pcs-commands-verbose Converts CMAN cluster configuration to a list of pcs commands which recreates the same cluster as Pacemaker cluster when exe‐ cuted. Commands will be saved to 'output' file. For other options see above. export pcs-commands|pcs-commands-verbose output=<filename> Creates a list of pcs commands which upon execution recreates the current cluster running on this node. Commands will be saved to 'output' file. Use pcs-commands to get a simple list of commands, whereas pcs-commands-verbose creates a list includ‐ ing comments and debug messages. pcsd certkey <certificate file> <key file> Load custom certificate and key files for use in pcsd. sync-certificates Sync pcsd certificates to all nodes found from current corosync.conf file (cluster.conf on systems running Corosync 1.x). WARNING: This will restart pcsd daemon on the nodes. clear-auth [--local] [--remote] Removes all system tokens which allow pcs/pcsd on the current system to authenticate with remote pcs/pcsd instances and vice-versa. After this command is run this node will need to be re-authenticated with other nodes (using 'pcs cluster auth'). Using --local only removes tokens used by local pcs (and pcsd if root) to connect to other pcsd instances, using --remote clears authentication tokens used by remote systems to connect to the local pcsd instance. node maintenance [--all] | [<node>]... Put specified node(s) into maintenance mode, if no node or options are specified the current node will be put into mainte‐ nance mode, if --all is specified all nodes will be put into maintenace mode. unmaintenance [--all] | [<node>]... Remove node(s) from maintenance mode, if no node or options are specified the current node will be removed from maintenance mode, if --all is specified all nodes will be removed from main‐ tenance mode. standby [--all | <node>] [--wait[=n]] Put specified node into standby mode (the node specified will no longer be able to host resources), if no node or options are specified the current node will be put into standby mode, if --all is specified all nodes will be put into standby mode. If --wait is specified, pcs will wait up to 'n' seconds for the node(s) to be put into standby mode and then return 0 on success or 1 if the operation not succeeded yet. If 'n' is not speci‐ fied it defaults to 60 minutes. unstandby [--all | <node>] [--wait[=n]] Remove node from standby mode (the node specified will now be able to host resources), if no node or options are specified the current node will be removed from standby mode, if --all is specified all nodes will be removed from standby mode. If --wait is specified, pcs will wait up to 'n' seconds for the node(s) to be removed from standby mode and then return 0 on success or 1 if the operation not succeeded yet. If 'n' is not specified it defaults to 60 minutes. utilization [<node> [<name>=<value> ...]] Add specified utilization options to specified node. If node is not specified, shows utilization of all nodes. If utilization options are not specified, shows utilization of specified node. Utilization option should be in format name=value, value has to be integer. Options may be removed by setting an option without a value. Example: pcs node utilization node1 cpu=4 ram= alert [config|show] Show all configured alerts. create path=<path> [id=<alert-id>] [description=<description>] [options [<option>=<value>]...] [meta [<meta-option>=<value>]...] Create new alert with specified path.
