I have never seen it listed as ONLINE (standby). Here's the ha.cf on quorumnode:
autojoin none
mcast eth0 239.0.0.43 694 1 0
warntime 5
deadtime 15
initdead 60
keepalive 2
node node1
node node2
node quorumnode
crm respawn

And here's the ha.cf on node[12]:
autojoin none
mcast br0 239.0.0.43 694 1 0
bcast br1
warntime 5
deadtime 15
initdead 60
keepalive 2
node node1
node node2
node quorumnode
crm respawn
respawn hacluster /usr/lib/heartbeat/dopd
apiauth dopd gid=haclient uid=hacluster

The only difference between these boxes is that quorumnode is a CentOS 5.5 box so it is stuck at heartbeat 3.0.3, whereas node[12] are both on Ubuntu 10.04 using the Ubuntu HA PPA, so they are running heartbeat 3.0.5. Would this make a difference?

I've removed this constraint

Here is the log from the DC for that same time period:

I will get this output the next time I can put the cluster in this state.
