ltcluster service unpause — Instruct all ltclusterd instances in the replication cluster to resume failover operations
This command can be run on any active node in the replication cluster to instruct all running ltclusterd instances to "unpause" (following a previous execution of ltcluster service pause) and resume normal failover/monitoring operation.
It's important to wait a few seconds after restarting LightDB on any node before running
ltcluster service pause
, as the ltclusterd instance
on the restarted node will take a second or two before it has updated its status.
LightDB must be accessible on all nodes (using the conninfo
string shown by
ltcluster cluster show
)
from the node where ltcluster service pause
is executed.
ltcluster service unpause
can be executed on any active node in the
replication cluster. A valid ltcluster.conf
file is required.
It will have no effect on nodes which are not already paused.
$ ltcluster -f /etc/ltcluster.conf service unpause NOTICE: node 1 (node1) unpaused NOTICE: node 2 (node2) unpaused NOTICE: node 3 (node3) unpaused
--dry-run
Check if nodes are reachable but don't unpause ltclusterd.
One of the following exit codes will be emitted by ltcluster service unpause
:
SUCCESS (0)
ltclusterd could be unpaused on all nodes.
ERR_LTCLUSTERD_PAUSE (26)
ltclusterd could not be unpaused on one or mode nodes.
