Hello everyone,
I'm a new man on linux cluster. I have built a two-node cluster (without qdisk), includes:
Redhat 6.4
cman
pacemaker
gfs2
My cluster could fail-over (back and forth) between two nodes for these 3 resources: ClusterIP, WebFS (Filesystem GFS2 mount /dev/sdc on /mnt/gfs2_storage), WebSite ( apache service)
My problem occurs when I stop/start node in the following order: (when both nodes started)
1. Stop: node1 (shutdown) -> all resource fail-over on node2 -> all resources still working on node2
2. Stop: node2 (stop service: pacemaker then cman) -> all resources stop (of course)
3. Start: node1 (start service: cman then pacemaker) -> only ClusterIP started, WebFS failed, WebSite not started

I don't have any glues to trace down this case, I just guess this problem comes from locking file system, please suggest me some advices.
Thank you.
