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.


     Files
          Filesystem-table format:

               column 1    block special file name of filesystem

               column 2    mount-point directory

               column 3    ``-r'' if to be mounted  read-only;  ``-d''
                           if remote

               column 4    (optional) filesystem type string

               column 5+   ignored

          White space separates columns.  Lines beginning with "#" are
          comments.  Empty lines are ignored.

          A typical filesystem-table might read:

               /dev/dsk/0s1   /usr -r S51K

     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).


     Notes
          The information displayed in Column 3 will  only  appear  if
          the  file  system  was  mounted  as  a  read-only  or remote
          resource.
