Lon, Thank you for your suggestion. In the meantime, I developed a script to do the unmount of a snapshot on stop and configured it as an additional resource agent of the type script. This works very well.

In theory you could delete the 'start' operation from the agent, but I think rgmanager will ignore that and try to start it anyway... You could edit the 'fs' agent and make the 'stop' and 'status' operations return 0 immediately, though. -- Lon -- 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
