-
Become the root role on a cluster node that is to host
the PostgreSQL component.
-
Ensure that all the PostgreSQL resources are online.
For each resource, perform the following steps:
-
Determine whether the resource is online.
# clresource status postgres-prim-rs
# clresource status postgres-sta-rs
# clresource status rolechg-rs
-
If the resource is not online, bring the resource online.
# clresource enable postgres-sta-rs
# clresource enable postgres-prim-rs
# clresource enable rolechg-rs
-
Reboot the primary node where the primary database runs.
# reboot
-
Confirm that the resource is now online on node
2.
# clresource status rolechg-rs
-
For a failback, log in as the Postgres user on the standby node and
resilver the primary node by executing scripts resilver-step1
and resilver-step2.
Note -
Ensure that you follow the configuration steps for the scripts.
