JAGag33099 (SR860678856): In a cluster of more than
3 nodes, node failed to join
What is the problem? In a cluster with more than 3 nodes, if 2 or more
nodes restart at the same time after certain failures and then try to
automatically join the cluster (through system startup), then one of the
nodes can fail to join the cluster. The cmrunnode command run by the
system startup script will time out. The syslog file on that node will
contain messages such as:
Feb 24 17:30:58 sienna syslog: /usr/sbin/cmrunnode -v ....
....
Feb 24 17:40:19 sienna cmcld[2729]: Cluster formation failed
Feb 24 17:40:19 sienna cmcld[2729]: Reason: Ran out of time for
automatically joining a cluster
In addition, one of the existing nodes in the cluster will have a message
such as this in syslog :
Feb 24 17:31:04 milan cmcld[2729]: Detected different
configuration data on node sienna
Feb 24 17:31:04 milan cmcld[2729]: Can not form cluster with
node sienna
What is the workaround? Run cmrunnode from the command line on the
node which has failed to join the cluster.
