[Ocfs2-users] Heartbeat write timeout to device dm-6 after 12000
milliseconds

I'm having a hard time figuring out what's going on with our cluster.
After 2 to 3 randomly fencing machines a day I have enabled 'HEARTBEAT
allow' debug output, see extract of the logfile below.
We have 5 volumes mounted from a Hitachi DF600F SAN over 2 multipath-tools
controlled QLA2340. I hope the 12 second timeout is a non-issue here. SAN
is healthy and file system performance is normal.
Nodes randomly fence both under load and while idle.
- What exactly is the meaning of 'changed 1 equal 0' in o2hb debug output?
- How do I find the link between the disk and the heartbeat region to
figure out which disk the failed heartbeat refers to?
- How is the heartbeat timeout configured?
- How can I debug further to find the cause of the fencing?
