Hello,
I currently have a 9 node centos 5.1 cman/gfs cluster which I've managed
to break.
It is broken in almost exactly the same way as stated in these two
previous threads:
http://www.spinics.net/lists/cluster/msg10304.html
http://www.redhat.com/archives/linux-cluster/2008-May/msg00060.html
However, I can find no resolution in the archives. My only guaranteed
resolution at this point is a cold restart of all nodes which to me
seems ridiculous (ie: I'm missing something).
To add a little details, I have nodes cluster1...9. Nodes 7 & 8 are
broken. When I fence/reboot them, cman starts but times out on starting
fencing. cman_tools nodes shows them as joined but the fence domain
looks broke.
Any ideas?
I have included some information for a good node, bad node, and
/var/log/messages from a good node that did the fencing.
Good Node:
