Xen dom0 and heartbeat
During testing of heartbeat 1 on a xen dom0, some strange errors appeared. One of the error messages was:
ERROR: No local heartbeat. Forcing shutdown
This error message was explained in the heartbeat FAQ but the explained causes didn’t make any sense.
An update from Xen 3 to Xen 3.0.4 didn’t solve the problem.
Updating heartbeat from v1 to v2 made the error disappear and heartbeat was now working without any problems.
Heartbeat v2 has a complete new config file. The main config file (ha.cf) is now an xml file. But don’t worry, if you don’t want to upgrade the config file, you can keep working with a v1 config file. You can’t take advantage of the new features of heartbeat v2 but at least you’re taking advantage of the bugfixes
