LVMLOCKCTL(8) LVMLOCKCTL(8)
lvmlockctl — Control for lvmlockd
lvmlockctl [options]
This command interacts with lvmlockd(8).
-h|--help
Show this help information.
-q|--quit
Tell lvmlockd to quit.
-i|--info
Print lock state information from lvmlockd.
-d|--dump
Print log buffer from lvmlockd.
-w|--wait 0|1
Wait option for other commands.
-f|--force 0|1
Force option for other commands.
-k|--kill vgname
Kill access to the VG when sanlock cannot renew lease.
-r|--drop vgname
Clear locks for the VG when it is unused after kill (-k).
-E|--gl-enable vgname
Tell lvmlockd to enable the global lock in a sanlock VG.
-D|--gl-disable vgname
Tell lvmlockd to disable the global lock in a sanlock VG.
-S|--stop-lockspaces
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 runs the command specified in
lvm.conf lvmlockctl_kill_command to deactivate LVs in the
VG. If the specified command is successful, locks will be
dropped for the VG in lvmlockd (the equivalent of
lvmlockctl --drop will be run.) If no command is
specified, or the command fails, then the user must
intervene to forcefully deactivate LVs in the VG, and if
successful, run lvmlockctl --drop. 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. When
lvmlockctl_kill_command is used, the --kill command may
run drop automatically. 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 command 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.
