Hello, I have found the same behaviour. Shutting down a cluster node without first stopping the cluster services results in a node that has not logged out from the cluster. The cluster may even fence the node and bring it back on-line. (it won't stay dead!) You can also leave the cluster with 'cman_tool leave': http://linux.die.net/man/8/cman_tool Tells CMAN to leave the cluster. You cannot do this if there are subsystems (eg DLM, GFS) active. You should dismount all GFS filesystems, shutdown CLVM, fenced and anything else using the cluster manager before using cman_tool leave. Look at 'cman_tool status|services' to see how many (and which) services are running. When a node leaves the cluster, the remaining nodes recalculate quorum and this may block cluster activity if the required number of votes is not present. If this node is to be down for an extended period of time and you need to keep the cluster running, add the remove option, and the remaining nodes will recalculate quorum such that activity can continue.

Technically it should, I suppose, but I've had it not work enough times that I've now created a little 'stop_cluster.sh' and 'start_cluster.sh' scripts that I run. -- Digimer E-Mail: digimer@xxxxxxxxxxx AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
