USAGE         top

   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.
