[Pacemaker] Different value on cluster-infrastructure between 2 nodes

[Pavlos Parissis]

Hi

I am doing a rolling upgrade of pacemaker from CentOS 6.3 to 6.4 and
when 1st node is upgraded and gets 1.1.8 version it doesn't join the
cluster and I ended up with 2 clusters.

In the logs of node1 I see
cluster-infrastructure" value="classic openais (with pluin)

but node2(still in centos6.3 and pacemaker 1.1.7) it has
cluster-infrastructure="openais"

I also see different dc-version between nodes.

Does anyone know if these could be the reason for node1 to not join the
cluster and decides to make its own cluster?

corosync communication looks fine

Printing ring status.
Local node ID 484162314
RING ID 0
        id      = 10.187.219.28
        status  = ring 0 active with no faults
RING ID 1
        id      = 192.168.1.2
        status  = ring 1 active with no faults


Cheers,
Pavlos
