umount_samfs(1M)

NAME
     umount_samfs - Unmounts a Sun QFS or SAM-QFS file system

SYNOPSIS
     umount -F samfs [-f] [generic_options] [-o await_clients=n]
     special | mount_point

AVAILABILITY
     SUNWsamfs

DESCRIPTION
     The umount command unmounts a currently mounted file system
     from the file system hierarchy.  The file system may be
     specified by either its mount point or its special (also
     known as its family set name).

     For more information on the mount(1M) command, see the
     mount(1M) man page and the mount_samfs(1M) man page.

     For more information on the umount command, see the
     umount(1M) man page.

OPTIONS
     -F samfs  Specifies that the file system being unmounted is
               of type samfs.  Both Sun QFS and SAM-QFS file
               systems are of type samfs.

     -f        Forcibly unmount the file system, i.e., unmount
               the file system even if it is busy.  This may fail
               or hang in some situations, particularly on
               clients if the metadata server does not have the
               FS mounted.

     generic_options
               One or more generic Solaris file system options.
               For a list of possible generic_options, see the
               umount(1M) man page.

     -o await_clients=n
               If the mounted file system is a Sun QFS or SAM-QFS
               shared file system and the current host is the
               metadata server for that file system, the umount
               command will wait for the specified period (n
               seconds) for any mounted clients to first unmount.
               The unmount command proceeds after either the last
               client host unmounts the file system, or the
               waiting period expires.

     special   The Family Set Name from the Sun QFS or SAM-QFS
               master configuration file (mcf).  For more
               information on this file, see the mcf(4) man page.

     mount_point
               The path name or directory at which the file
               system is mounted.  If the mount_point had any
               contents prior to the mount operation, these
               become accessible after the umount command
               successfully completes.

EXAMPLES
     # umount samfs1

     Unmount the file system whose family set name is samfs1.  If
     the file system is in use, the command will fail.

     # umount -f -o await_clients=30 /qfs1

     Forcibly unmount the file system mounted on /qfs1.  If the
     file system is a shared file system, and the local host is
     the metadata server for that file system, then umount will
     wait up to 30 seconds for the clients to unmount before
     issuing the unmount.  If the file system is not shared, or
     has no mounted clients, or the local host is not the
     metadata server, the await_clients option has no effect.
     The file system is forcibly unmounted.
