    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.
