mountall(1M)

NAME

mountall, umountall — mount and unmount multiple file systems

SYNOPSIS

/sbin/mountall [-F FStype] [-l|-r] [file_system_table | -]

/sbin/mountall [-l|-r] [-m]

/sbin/mountall [-n]

/sbin/umountall [-F FStype] [-k] [-l|-r]

DESCRIPTION

mountall is used to mount file systems according to file_system_table. By default, /etc/fstab is the file_system_table. If a dash (-) is specified, mountall reads file_system_table from the standard input; the standard input must be in the same format as the /etc/fstab.

Before each file system is mounted, a check is done using fsck (see fsck(1M)) to ensure that the file system is mountable. If the file system is not mountable, it is repaired by fsck before the mount is attempted.

umountall causes all mounted file systems except the non-removable file systems such as root to be unmounted.

Options

mountall and umountall recognize the following options:

-F FStype: Specify the file system type (FStype) to be mounted or unmounted.
-l: Specify action on local file systems only.
-r: Specify action on remote file systems only.
-k: Send a SIGKILL signal to processes that have files opened.
-m: Attempt to mount all the unmounted file systems. This option will not perform the file system consistency check and repair.
-n: Perform the file system consistency check and repair on all unmounted file system. This option will not mount the file systems.

DIAGNOSTICS

Error and warning messages may originate from fsck, mount, fuser, or umount. See fsck(1M), mount(1M), or fuser(1M) to interpret the error and warning messages.

EXAMPLES

Mount all unmounted file systems listed in /etc/fstab:

mountall 

Mount all local file systems listed in /etc/fstab:

mountall -l 

Mount all remote file systems listed in /etc/fstab:

mountall -r 

Mount all local hfs file systems:

mountall -F hfs -l 

Unmount all NFS file systems and kill any processes that have files opened in the file system:

umountall -F nfs -k 

WARNINGS

umountall, especially with the -k option, should be used with extreme caution, because it can cause severe damage.

The -n option may not be available in future releases.

mountall may not be effective with some cases of LOFS file systems.

FILES

/etc/fstab: Static information about the file systems
