Halting a single node in the cluster will seem like a communication failure to the other nodes. Errors will be logged and the fencing code will get called, etc. So there’s a procedure for properly shutting down a cluster.

Halting a single node in the cluster will seem like a communication failure to the other nodes. Errors will be logged and the fencing code will get called, etc. So there’s a procedure for properly shutting down a cluster. Here’s what you should do: Use the “cman_tool leave remove” command before shutting down each node. That will force the remaining nodes to adjust quorum to accomodate the missing node and not treat it as an error.
