MOUNTALL(ADM)                        UNIX System V


     Name
          mountall, umountall - mount, unmount multiple file systems


     Syntax
          /etc/mountall [-] [filesystem-table] ...
          /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  a filesystem-table. (/etc/default/filesys is the default
          filesystem table.) The special file name "-" reads from  the
          standard input.

          Before each file system is  mounted,  it  is  checked  using
          fsstat(ADM)  to  see  if  it appears mountable.  If the file
          system does not  appear  mountable,  it  is  checked,  using
          fsck(ADM), before the mount is attempted.

          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
          root 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).
