2.4.1 Manual failover

Mobile AG resources

Manually fail over the AG resource ag_cluster to the cluster node nodeName2:

Sudo pcs resource move ag_cluster-master nodeName2-master

Delete position constraint

First look at the location constraints of the resources added on the new target node:

Sudo pcs constraint list-full

For example:

Enabled on: Node1 (score:INFINITY) (role: Master) (id:cli-prefer-ag_cluster-master)

Cli-prefer-ag_cluster-master is the constraint ID that needs to be deleted.

Perform the deletion:

Sudo pcs constraint remove cli-prefer-ag_cluster-master

Note: automatic failover does not add positional constraints, so cleanup is not required.
