search for: o2cb

Hi, I might be overlooking the obvious, but I have yet to find "/etc/init.d/o2cb" however, I read that configuration uses this init script. Where is it? From: ocfs2-tools-1.2.4/README.O2CB [Starting the OCFS2 Clustering Services] O2CB is comprised of a simple node manager, heartbeat, TCP protocol, and DLM. The basic steps in startup are as follows: 1) Load the node...

Hi Greg, The following two patches move /sys/o2cb into /sys/fs/o2cb as we previously discussed. A symlink is created to maintain compatibility with existing versions of ocfs2-tools. A patch to automatically search /sys/fs/o2cb has been committed to the ocfs2-tools repo and a release with that code shouldn't be too far out. Old versions of ocfs...

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...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, another problem I did not find a solution for... I ran "o2cb configure" and configured a cluster named "ocfs2". Lazy me, I did not invent a new name. Now this cluster must be renamed to avoid confusion, the name has to change to "sapcluster". I changed /etc/ocfs2/cluster.conf to the new name and ran "o2cb configure" again...

Hi I have: SLES 10 SP2 (2.6.16.60-0.21-smp) ocfs2-tools-1.4.0-0.3 ocfs2console-1.4.0-0.3 and I can't change "heartbeat dead threshold" value.

...post this evening as below Hi All, since the post I have made some kind of a progress 1.

On RHEL4 also, the service o2cb starts later than _netdev device mounts. So mount fails. Should the o2cb service start earlier to fix this?
