mountall(ADM)                   19 June 1992                   mountall(ADM)


 Name

    mountall, umountall - mount, unmount multiple file systems

 Syntax

    /etc/mountall [ -a ]

    /etc/umountall [ -k ]

 Description

    These commands can be executed only by the super user.

    The mountall command is used to mount filesystems according to
    /etc/default/filesys.

    Before each filesystem is mounted, it is checked using fsstat(ADM) to see
    if it appears to be mountable.  The default behavior, if the file system
    does not appear to be mountable, is to check it using fsck(ADM) before
    the mount is attempted. (This behaviour may be modified by
    /etc/default/filesys file -- see filesys(F).)

    mountall is called with the -a when the system autoboots.  The -a flag
    causes output messages to be written to the file /etc/bootlog, and later
    mailed to the system administrator (see boot(HW)).

    The umountall command causes all mounted file systems except the root
    filesystem to be unmounted.  The -k option sends a SIGKILL signal, via
    fuser(ADM), to processes that have files open.

 Diagnostics

    No messages are printed if the filesystems are mountable and clean.

    Error and warning messages come from fsck(ADM), fsstat(ADM), and
    mount(ADM).
