repmgr service pauserepmgrdpausingrepmgr service pauserepmgr service pauseInstruct all &repmgrd; instances in the replication cluster to pause failover operationsDescription
This command can be run on any active node in the replication cluster to instruct all
running &repmgrd; instances to "pause" themselves, i.e. take no
action (such as promoting themselves or following a new primary) if a failover event is detected.
This functionality is useful for performing maintenance operations, such as switchovers
or upgrades, which might otherwise trigger a failover if &repmgrd;
is running normally.
It's important to wait a few seconds after restarting PostgreSQL on any node before running
repmgr service pause, as the &repmgrd; instance
on the restarted node will take a second or two before it has updated its status.
will instruct all previously paused &repmgrd;
instances to resume normal failover operation.
Prerequisites
PostgreSQL must be accessible on all nodes (using the conninfo string shown by
repmgr cluster show)
from the node where repmgr service pause is executed.
Executionrepmgr service pause can be executed on any active node in the
replication cluster. A valid repmgr.conf file is required.
It will have no effect on previously paused nodes.
Example
$ repmgr -f /etc/repmgr.conf service pause
NOTICE: node 1 (node1) paused
NOTICE: node 2 (node2) paused
NOTICE: node 3 (node3) pausedOptions
Check if nodes are reachable but don't pause &repmgrd;.
Exit codes
One of the following exit codes will be emitted by repmgr service unpause:
&repmgrd; could be paused on all nodes.
&repmgrd; could not be paused on one or mode nodes.
