System Administration Commands mountall(1M)
NAME
mountall, umountall - mount, unmount multiple file systems
SYNOPSIS
mountall [-F FSType] [-l -r] [filesystemtable]
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 table. The file system table must be in vfstab(4)
format. If no filesystemtable is specified, /etc/vfstab is
used. If - is specified as filesystemtable, 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 filesystemtable.
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, moun-
tall and umountall limit their actions to the FSType speci-
fied. 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.

System Administration Commands mountall(1M)
-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
SIGKIL 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.
-Z Apply the action(s) only to the file systems
mounted in non-global zones. By default, umoun-
tall 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.
