NAME

mountall, umountall- Mount, unmount multiple file systems

SYNOPSIS

mountall [-F   FSType] [-l| -r] [file_system_table]
umountall [-k] [-s] [-F   FSType] [-l| -r]
umountall [-k] [-s] [-h   host]

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 will be used. If `-' is specified as file_system_table , mountall will read the file system table from the standard input. mountall only mounts those file systems with the mount at boot field set to yes in the file_system_table .

Each file system which has an fsckdev entry specified in the file system table will be checked using fsck(1M) in order to determine if it may be safely mounted. 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 will be 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 will unmount busy filesystems, even if the -k option is specified.

mountall and umountall must run with the sys_mount privilege.

Mandatory and discretionary read access are required to both the mount point and the device being mounted; to override MAC and DAC restrictions requires privilege as described in Intro(2) . To succeed in all cases, the mountall and umountall commands need the privileges: file_mac_read , file_dac_read , file_mac_write , file_dac_write , file_mac_search , file_dac_search , net_privaddr , proc_setsl , sys_mount , and sys_trans_label .

When mounting a UFS file system, mount should assert the sys_fs_config privilege. Otherwise, the mount succeeds, but logging is not enabled/disabled, errno is set to EPERM , and the user sees an error message.

OPTIONS

-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 may not show up immediately. There is no guarantee that umountall will unmount busy filesystems, even if the -k option is specified.

-l

Limit the action to local file systems.

-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

SUMMARY OF TRUSTED SOLARIS CHANGES

Trusted Solaris security policy applies when mounting and unmounting file systems.

mountall and umountall must run with the sys_mount privilege.

Mandatory and discretionary read access are required to both the mount point and the device being mounted; to override MAC and DAC restrictions requires privilege as described in Intro(2) . To succeed in all cases, the mountall and umountall commands need the privileges: file_mac_read , file_dac_read , file_mac_write , file_dac_write , file_mac_search , file_dac_search , net_privaddr , proc_setsl , sys_mount , and sys_trans_label .

When mounting a UFS file system, mount should assert the sys_fs_config privilege. Otherwise, the mount succeeds, but logging is not enabled/disabled, errno is set to EPERM , and the user sees an error message.

Mount-time security attributes may be specified in the vfstab_adjunct file.

DIAGNOSTICS

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

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