When the node running the group prod failed, the test group on the other node was stopped and the prod group was started. After the failed node was online again, the prod group was moved to the other node. BUT the test group was first started, then the prod group was stopped and started on the other node. There was a very short time where both groups were active on the same node. Do you have an ordering constraint between them? We use a RA to set the home directory for some users, and so the path gets first set and then unset by this sequence. There is no order defined between these groups to enable parallel starts on different nodes. Is this a definition problem or a bug. Nevertheless this behavior looks strange for me!
