Hi all

I have set up a cluster of 5 nodes, they all share a SAN and mount the same disc, the file system on the disc is ocfs2.

Every thing was fine then I simulated a crash of one of the nodes, once back online the node wouldn't re mount the drive, an error saying, waiting for heartbeat to initialize DLM, so I restarted all the nodes and now none of them will mount the drive, all have the same error

when I run /etc/init/o2cb status I get

Module "configfs": Loaded
Filesystem "configfs": Mounted
Module "ocfs2_nodemanager": Loaded
Module "ocfs2_dlm": Loaded
Module "ocfs2_dlmfs": Loaded
Filesystem "ocfs2_dlmfs": Mounted
Checking cluster ocfs2: Online
Checking heartbeat: Not active

Does any one know how to make heartbeat active again????

this is the output from crm_mon

I can make cluster resources, like a ip address to ping and they work fine, I just can't mount this disc???

Thanks in advance
