Re: [Linux-cluster] Shutdown/startup



Hey Paul,

I didn't reply to the list with this.

I couldn't believe it either when I found out that RHCS 3.x worked this way... With RHCS 3.x the fencing deamon is evil, you practically have to chkconfig off the cluster service let him get fenced and bring the system back up.

I thought for sure this would have been fixed in the future version.

So how does one properly shutdown and/or start up a GFS 6.1 cluster. Documentation on the procedures are surprisingly sparse. For example, what I've experienced during shutdown are messages like:

CMAN: sendmsg failed: -101
CMAN: we are leaving the cluster.

from the node shutting down while the the other nodes report that this node needs to be fenced off. What?! Fenced during a controlled shutdown? Is that correct? During a complete cluster shutdown, of course quorum, at some point is lost, freezing the nodes that have not completely shutdown forcing a hard reset on those nodes. I'm probably missing something trivial here, but this doesn't seem right.

Start up also suffers from the "quorum" problem, but it seems to recovery once enough nodes are up.
