nmountall(NADM)                 19 June 1992                 nmountall(NADM)


 Name

    nmountall - nmountall, numountall - mount, unmount multiple filesystems

 Syntax

    /etc/nmountall
    /etc/numountall

 Description

    The nmountall command is used to mount NFS filesystems according to
    entries in /etc/fstab.  It is strongly recommended that the NFS mount
    option, bg, be used for filesystems which are mounted automatically dur-
    ing startup.  This will prevent startup processing from hanging while
    trying to mount a filesystem from a very slow or dead server.

    The numountall command causes all NFS mounted filesystems to be
    unmounted.  Processes which hold open files or have current directories
    on these filesystems are killed by being sent a series of signals.  The
    first signal sent is SIGHUP.  One second later, SIGTERM will be sent.
    Finally, one second later, SIGKILL will be sent.

    These commands may be executed only by the super user.

 Files

    Filesystem-table format:

         column 1        remote filesystem name to be mounted

         column 2        mount-point directory

         column 3        "-r" if to be mounted read-only

         column 4        filesystem type string

         column 5+       ignored

    White space separates columns.  Any lines beginning with ``#'' are com-
    ments.  Empty lines are ignored.

    A typical filesystem-table entry might read:

         srcmachine:/usr/src     /usr/src        -r      NFS,soft,bg

    signal(S).

 Diagnostics

    nmountall will print the mount commands that it will run before it runs
    them.

    The numountall command prints the list of process-ids to which it sent
    signals.  The list of filesystems which are being unmounted is also
    printed.

 Notes

    The information displayed in Column 3 will appear only if the filesystem
    was mounted read-only.
