We have configred the suse11 HA according to the HAE guideline. By the add of the dlm,o2cb and ocfs2 Filesystem resources, all the nodes in the cluster are expected to access the shared storage simultaneously. But we met an issue when we shutdown(not reboot) one node of the cluster, which made the shared memory unaccessable to all the other nodes. What the issue might be, anybody could help? Thanks a lot.
