RE: [Linux-cluster] DLM locks with 1 node on 2 node cluster



(resending since forgot to include linux-cluster redhat com)
I am using manual fencing with gnbd fencing. Here is the tail on
/var/proc/messages:

Aug 28 14:17:06 bof227 fenced[2497]: bof226 not a cluster member after 0 sec
post_fail_delay Aug 28 14:17:06 bof227 kernel: CMAN: removing node bof226
from the cluster : Missed too many heartbeats Aug 28 14:17:06 bof227
fenced[2497]: fencing node "bof226"
Aug 28 14:17:06 bof227 fence_manual: Node bof226 needs to be reset before
recovery can procede.  Waiting for bof226 to rejoin the cluster or for
manual acknowledgement that it has been reset (i.e. fence_ack_manual -n
bof226)

It's trying to fence the failed node and won't continue with recovery until
that's done.  What fencing method are you using in cluster.conf?
Are there any fencing error messages in /var/log/messages?  What does your
cluster.conf look like?
