Re: [Linux-cluster] uncontrolled entry



That was extremely hard to read, and the cluster.conf was edited to such
a degree that it was no longer formatted correctly. That said, I think I
can see enough to have an idea what happened.

You do not manage the iSCSI connection or the gfs2 partition in the
cluster, so the failure of the iSCSI connection and subsequent failure
of the gfs2 partition were not a concern of the cluster. Corosync on
that node was not interrupted, so the node was not fenced (that's only
needed to put a node in an unknown state back into a known state).

Have you resolved the iSCSI connection problem? As for gfs2, you stopped
the cluster while it was still (trying to) run, so it's probably
blocked. I'm not a GFS2 expert, so I can't speak to the internals of
what is going on.

If it was me, I would reboot the node, make sure iscsi was working after
the reboot and then restart cman. I'd also put the storage components
under the cluster's control, too.
