Hi of all, I'm trying to setup a primary/primary DRBD with openais, pacemaker and ocfs2. I can't follow the new howto example in clusterlabs site because in my distribution (centos 5.3) there isn't the dlm package and the corrispective ocf ra.
So I have followed the steps in the drbd site but it doesn't work well. In pacemaker I have created a master resource with the option master-max=2 and primary/slave monitor operation, so when I start the resource through pacemaker drbd resource goes primary in both the nodes It's OK. If I unplug the replication link (I have 2 ethernet card with 'rrp_mode: active' in openais configuration) the node with role DC creates a constraint in pacemaker (fence-peer /usr/lib64/drbd/crm-fence.sh" in drbd.conf) and the drbd resource goes to secondary state in the other node; it's OK. If I unplug the replication link when the drbd resource is mounted the node with role DC creates a constraint in pacemaker but the drbd resource in the other node remains in primary state and it becomes 'unmanaged' in pacemaker. It's not OK!!!! There is a method to stop this drbd resource also when this is mounted?? Thanks to all!!!!! Bye.
