System Administration Commands mountall(1M)
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_system_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 umoun-
tall limit their actions to the FSType specified. There is
no guarantee that umountall unmounts busy file systems, 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.

System Administration Commands mountall(1M)
-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 guaran-
tee 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. 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.
