What does the cluster message "ccsd: Unable to connect to cluster infrastructure" mean in a RHEL 5 cluster?
Issue
- I have started my Highly Available cluster but the services do not start or have issues failing over.
- The message logs are full of errors like:
ccsd: Unable to connect to cluster infrastructure after N seconds
- Unable to connect to cluster, one of our active/passive production cluster nodes suddenly lost its cluster infrastructure and cluster went down. What would be possible cause behind the incident.
Environment
- Red Hat Enterprise Linux (RHEL) 5 with the High Availability Add On
