Hello All, I have multiple OCFS2 clusters on SLES10 SP2 running Xen. We needed to increase the O2CB_HEARTBEAT_THRESHOLD from 31 up to 61 and did so successfully on 2 of our 3 clusters.
However on one of the three clusters we are not able to change the value. The /etc/sysconfig/o2cb file contains 61 as the threshold after reconfiguring via /etc/init.d/o2cb configure, we reconfigure all 3 nodes at the same time after unmounting the volume and stopping ocfs2 and o2cb on all nodes in the cluster but on restart the value is reset to 31. We have even gone so far as to change the default value in the /etc/init.d/o2cb script from 31 to 61 thinking that must be where the setting of 31 is coming from and even then, the value is set back to 31. Oh, and yes, we have rebooted with the new values in both the /etc/sysconfig/o2cb config and with our change of the default value in /etc/init.d/o2cb with no luck. Is anyone aware of a condition where the O2CB_HEARTBEAT_THRESHOLD stays at 31 regardless of what it is changed to? Is the heartbeat region on disk possibly causing this? Any guidance in tracking this down would be appreciated.
