MOUNTALL(8) Maintenance Commands and Procedures MOUNTALL(8)

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
table. The file system table must be in vfstab(5) 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(8). 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
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(8) 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.


-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.

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

DIAGNOSTICS

No messages are printed if the file systems are mountable and clean.


Error and warning messages come from fsck(8) and mount(8).

NOTES

At this time, NFS is the only remote file system supported by the -l,
-r, and -h options.
