52 info
53 This collects and displays lock state from lvmlockd. The display is
54 primitive, incomplete and will change in future version. To print the
55 raw lock state from lvmlockd, combine this option with --dump|-d.
56
57
58 dump
59 This collects the circular log buffer of debug statements from lvmlockd
60 and prints it.
61
62
63 kill
64 This is run by sanlock when it loses access to the storage holding
65 leases for a VG. It currently emits a syslog message stating that the
66 VG must be immediately deactivated. In the future it may automatically
67 attempt to forcibly deactivate the VG. For more, see lvmlockd(8).
68
69
70 drop
71 This should only be run after a VG has been successfully deactivated
72 following an lvmlockctl --kill command. It clears the stale lockspace
73 from lvmlockd. In the future, this may become automatic along with an
74 automatic handling of --kill. For more, see lvmlockd(8).
75
76
77 gl-enable
78 This enables the global lock in a sanlock VG. This is necessary if the
79 VG that previously held the global lock is removed. For more, see lvm‐
80 lockd(8).
81
82
83 gl-disable
84 This disables the global lock in a sanlock VG. This is necessary if
85 the global lock has mistakenly been enabled in more than one VG. The
86 global lock should be disabled in all but one sanlock VG. For more,
87 see lvmlockd(8).
88
89
90 stop-lockspaces
91 This tells lvmlockd to stop all lockspaces. It can be useful to stop
92 lockspaces for VGs that the vgchange --lock-stop comand can no longer
93 see, or to stop the dlm global lockspace which is not directly stopped
94 by the vgchange command. The wait and force options can be used with
95 this command.
