USAGE

   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.
