Stonith resources didn't get created although fencing.yaml was used to define them.

Solution Verified - Updated -

Environment

  • Red Hat OpenStack Platform 13.0

Issue

  • Stonith fails with below error because it was enabled and could not find any stonith devices to fence as defined by fencing.yaml
    # crm_verify -L -V
    error: unpack_resources:     Resource start-up disabled since no STONITH resources have been defined
    error: unpack_resources:     Either configure some or disable STONITH with the stonith-enabled option
    error: unpack_resources:     NOTE: Clusters with shared data need STONITH to ensure data integrity

Resolution

  • The file fencing.yaml is used to define stonith resources.
  • Generate fencing.yaml using below command
    openstack overcloud generate fencing --ipmi-lanplus --ipmi-level administrator --output fencing.yaml instackenv.json
  • Deploy overcloud again by passing fencing.yaml environment file.

Root Cause

  • The MAC address must always be in small alphabets instead of capitals for stonith resources to be created.
