Re: [Linux-cluster] uncontrolled entry



Rebooting the one node should not impact GFS2 on the other nodes. I
don't know if you can kill -9 gfs2. In my experience, you need to
reboot. There is a decent chance it will fail to shut down, so I usually
handle cases like this by going to a good node and running 'fence_node
<victim>'. That will forcibly reboot it and tell the cluster to reap any
locks the hung node might still have.

Of course, I know little about your setup. If you need more
authoritative advice, I'd recommend opening a support ticket with Red Hat.
