First of all, is there a way I can test to see if my Brocade switch is actually doing any fencing or not? I get the sense it's doing nothing. I think this because my cluster is terribly unstable. If I reboot a node, that's fine, it works, the cluster stays up. However, if one of the nodes crashes in any manner, it takes down everything to the point of having to shut down every machine and starting it all one at a time. If a drive get's moved on my FC storage, the cluster crashes. If the storage is rebooted, the cluster crashes. If I change pretty much anything on the storage, the cluster crashes, it's nuts. The way it seems to start is that one node seems to have a kernel panic which sets off the rest. I know this is limited information but I need somewhere to start. I can't even begin to think of using this in a production environment, no one would get any sleep watching over this to make sure it's all up :).
