Next time this happens collect the following from each node: group_tool -v group_dool dump group_tool dump fence anything from /var/log/messages *** This bug has been marked as a duplicate of 217449 *** Moving all RHCS ver 5 bugs to RHEL 5 so we can remove RHCS v5 which never existed. |
Description of problem: This may be related to 210641 or related to other cman/dlm daemon start stop issues that have been filed. I been playing around with starting and stoping cman in loops on a four node cluster and I always seem to get into a state were fenced won't die on one or more of the machines in the cluster.
