    NAME
           mountall, umountall - mount, unmount multiple file systems
    
    SYNOPSIS
           mountall [-F FSType] [-l | -r] [file_system_table]
    
    
           umountall [-k] [-s] [-F FSType] [-l | -r] [-n]  [-Z]
    
    
           umountall [-k] [-s] [-h host] [-n] [-Z]
    
    
    DESCRIPTION
           mountall  is  used to mount file systems specified in a file system ta-
           ble. The file system table must be in vfstab(4) format. If no file_sys-
           tem_table  is  specified,  /etc/vfstab  is  used.  If - is specified as
           file_system_table, mountall reads the file system table from the  stan-
           dard  input.  mountall mounts only those file systems with the mount at
           boot field set to yes in the file_system_table.
    
    
           For each file system in the file system table, the following  logic  is
           executed:  if  there  exists  a  file/usr/lib/fs/FSType/fsckall,  where
           FSType is the type of the file system, save that file system in a  list
           to   be   passed   later,   and  all  at  once,  as  arguments  to  the
           /usr/lib/fs/FSType/fsckall   script.   The   /usr/lib/fs/FSType/fsckall
           script checks all of the file systems in its argument list to determine
           whether they can be safely mounted.  If  no  /usr/lib/fs/FSType/fsckall
           script  exists  for  the  FSType of the file system, the file system is
           individually checked using fsck(1M). If the file system does not appear
           mountable,  it  is fixed using fsck before the mount is attempted. File
           systems with a - entry in the fsckdev field are mounted  without  first
           being checked.
    
    
           umountall  causes  all  mounted file systems in the current zone except
           root,  /usr,  /var,  /var/adm,  /var/run,  /proc,  and  /dev/fd  to  be
           unmounted.  If  the  FSType  is specified, mountall and umountall limit
           their actions to the FSType  specified.  There  is  no  guarantee  that
           umountall  unmounts  busy file systems, even if the -k option is speci-
           fied.
    
    OPTIONS
           The following options are supported:
    
           -F         Specify the FSType of the  file  system  to  be  mounted  or
                      unmounted.
    
    
           -h host    Unmount  all  file  systems  listed  in /etc/mnttab that are
                      remote-mounted from host.
    
    
           -k         Use the fuser -k mount-point command. See the fuser(1M)  for
                      details.  The  -k  option  sends  the SIGKILL signal to each
                      process using the file. As this option spawns kills for each
                      process,  the  kill  messages might not show up immediately.
                      There is no guarantee that umountall unmounts busy file sys-
                      tems, even if the -k option is specified.
    
    
           -l         Limit the action to local file systems.
    
    
           -n         List  the  actions that would be performed for the specified
                      options, but do not actually execute these actions.  Repeat-
                      ing  the  command  without the -n option executes the listed
                      actions, assuming that the /etc/mnttab file has not  changed
                      in the interval prior to repeating the command.
    
    
           -r         Limit the action to remote file system types.
    
    
           -s         Do not perform the umount operation in parallel.
    
    
           -Z         Apply  the  action(s)  only  to the file systems  mounted in
                      non-global zones. By default, umountall unmounts  only  file
                      systems mounted in the current zone. Option -Z is ignored if
                      used in a non-global zone.

    DIAGNOSTICS
           No messages are printed if the file systems are mountable and clean.
    
    
           Error and warning messages come from fsck(1M) and mount(1M).
    
    NOTES
           At  this  time, NFS is the only remote file system supported by the -l,
           -r, and -h options.
