umount_samfs - Unmounts a Sun QFS or SAM-QFS file system
umount -F samfs [-f] [generic_options] [-o await_clients=n]
special | mount_point
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.
-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
One or more generic Solaris file system options.
For a list of possible generic_options, see the
umount(1M) man page.
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.
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
# 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.
