[Pacemaker] Problem during Cluster Upgrade

[Karl Rößmann]

Hi all,

I'm upgrading a three node cluster from SLES 11 SP1 to SLES SP2 node by node.
the upgrade includes:
          corosync-1.3.3-0.3.1     to corosync-1.4.1-0.13.1
          pacemaker-1.1.5-5.9.11.1 to pacemaker-1.1.6-1.27.26
          kernel 2.6.32.54-0.3-xen to 3.0.13-0.27-xen

After Upgrading the first node and restarting the cluster I get these
never ending messages on the DC (which is not the updated node)

Apr 11 14:19:26 orion14 corosync[6865]:   [TOTEM ] Type of received  
message is wrong...  ignoring 6.
Apr 11 14:19:27 orion14 corosync[6865]:   [TOTEM ] Type of received  
message is wrong...  ignoring 6.
Apr 11 14:19:28 orion14 corosync[6865]:   [TOTEM ] Type of received  
message is wrong...  ignoring 6.
Apr 11 14:19:29 orion14 corosync[6865]:   [TOTEM ] Type of received  
message is wrong...  ignoring 6.

the updated node is still in STANDBY mode.
Should I ignore the message and put the mode to ONLINE ?
I don't want the cluster to crash, there are running services
on the other two nodes.
So now I stopped the openais on the updated node: no more messages.
the other two nodes are still up and working.

Any ideas ?

Karl
