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 table. 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 standard
       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 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 umountall 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 specified options, but do not actually execute	these  actions.  Repeating
		       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.

FILES

       /etc/mnttab		       Mounted file system table

       /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 systems of type FSType

       Error and warning messages come from fsck(1M) and mount(1M).
