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]

       umountall [-k] [-s] [-h host] [-n]

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 in-
       dividually 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 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 sys-
       tems, even if the -k option is specified.

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	umoun-
		       tall unmounts busy file systems,	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	speci-
		       fied options, but do not	 actually  execute  these  ac-
		       tions. Repeating	the command without the	-n option exe-
		       cutes 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.

FILES

       /etc/vfstab		       Table of	file system defaults

       /usr/lib/fs/FSType/fsckall      Script called by	 mountall  to  perform
				       the  file system	check of all file sys-
