Pacemaker: manual resource migration

This document (000020246) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 12
SUSE Linux Enterprise High Availability Extension 12

Situation

Failback to cluster primary node from secondary node when the primary rebooted and came online.

Resolution

Check if cli-* constraints are put into the cib.

For example:
# crm configre show
...
location cli-prefer-<resource name> <resource name> role=Started inf: <node name>
...
If a cli-prefer constraints is present in the cib (see the example above), upon rejoin the cluster resource will be forced back to that node.

The constraint must be removed with the following command:
# crm resource unmigrate <resource | group>

Cause

The cli-* constraints are created in the cib when an user manually migrates a resource.  These constraints should always be removed from the cluster.  Normally users should use the unmigrate right after migrate.  The unmigrate will remove any cli-* constraints it adds to the cluster.
