repmgr service pause — Instruct all repmgrd instances in the replication cluster to pause failover operations
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.
repmgr service unpause will instruct all previously paused repmgrd instances to resume normal failover operation.
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.
repmgr 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.
$ repmgr -f /etc/repmgr.conf service pause NOTICE: node 1 (node1) paused NOTICE: node 2 (node2) paused NOTICE: node 3 (node3) paused
--dry-run
Check if nodes are reachable but don't pause repmgrd.
One of the following exit codes will be emitted by repmgr service unpause
:
SUCCESS (0)
repmgrd could be paused on all nodes.
ERR_REPMGRD_PAUSE (26)
repmgrd could not be paused on one or mode nodes.
