The only reliable way I have found (rhel4 and 5) is this:
1: Migrate all services off the node.
2: Unmount as many GFS disks as possible.

The other nodes will recover quickly.
"cman leave (remove) (force)" sometimes works but often doesn't.

i want to share fc-san, do you know which is better?

Personal observation: GFS and GFS2

Hi,
I think the problem is solved. I was using a 9000bytes MTU on the Xen virtual

Thank you all.
The problem I have is that I don't seem to be able to get out of the cluster
gracefully, even if I stop the services manually in the right order.
For example, I joined the cluster manually by starting cman, clvmd and gfs2
in the order and everything is working just fine.
Then I want

Hello,
can you point me to some documentation of the new cluster architecture
available in RHEL6? I'm interested to learn about the internals.
I'm thinking about documents like the "Cluster2 architecture"
(http://people.redhat.com/teigland/cluster2-arch.txt), or "Symmetric
Cluster Architecture
and
