LVMLOCKCTL(8) LVMLOCKCTL(8)
lvmlockctl — Control for lvmlockd
This command interacts with lvmlockd(8).
lvmlockctl [options]
--help | -h
Show this help information.
--quit | -q
Tell lvmlockd to quit.
--info | -i
Print lock state information from lvmlockd.
--dump | -d
Print log buffer from lvmlockd.
--wait | -w 0|1
Wait option for other commands.
--force | -f 0|1
Force option for other commands.
--kill | -k vgname
Kill access to the VG when sanlock cannot renew lease.
--drop | -r vgname
Clear locks for the VG when it is unused after kill (-k).
--gl-enable | -E vgname
Tell lvmlockd to enable the global lock in a sanlock VG.
--gl-disable | -D vgname
Tell lvmlockd to disable the global lock in a sanlock VG.
--stop-lockspaces | -S
Stop all lockspaces.
info
This collects and displays lock state from lvmlockd. The display is
primitive, incomplete and will change in future version. To print
the raw lock state from lvmlockd, combine this option with --dump|-d.
dump
This collects the circular log buffer of debug statements from
lvmlockd and prints it.
kill
This is run by sanlock when it loses access to the storage holding
leases for a VG. It currently emits a syslog message stating that
the VG must be immediately deactivated. In the future it may
automatically attempt to forcibly deactivate the VG. For more, see
lvmlockd(8).
drop
This should only be run after a VG has been successfully deactivated
following an lvmlockctl --kill command. It clears the stale
lockspace from lvmlockd. In the future, this may become automatic
along with an automatic handling of --kill. For more, see
lvmlockd(8).
gl-enable
This enables the global lock in a sanlock VG. This is necessary if
the VG that previously held the global lock is removed. For more,
see lvmlockd(8).
gl-disable
This disables the global lock in a sanlock VG. This is necessary if
the global lock has mistakenly been enabled in more than one VG. The
global lock should be disabled in all but one sanlock VG. For more,
see lvmlockd(8).
stop-lockspaces
This tells lvmlockd to stop all lockspaces. It can be useful to stop
lockspaces for VGs that the vgchange --lock-stop comand can no longer
see, or to stop the dlm global lockspace which is not directly
stopped by the vgchange command. The wait and force options can be
used with this command.
