Hi. I'm pretty new to ocfs2 and clusters. I'm trying to make ocfs2 running over a drbd device. I know it's not the best solution but for now i must deal with this. I set up drbd and work perfectly. I set up ocfs and i'm not able to make it to work. /etc/init.d/o2cb status: Module "configfs": Loaded Filesystem "configfs": Mounted Module

I think I've established that the OCFS2 heartbeat patch wasn't committed to the Linux kernel until 2.6.20. I think I've also established that Redhat haven't backported the patch to their RHEL-5 ker...

When attempting to mount the OCFS2 file system I'm getting the following error message: ocfs2_hb_ctl: Internal logic failure while starting heartbeat mount.ocfs2: Error when attempting to run /sbin/ocfs2_hb_ctl: "Operation not permitted" I followed the steps given in the users_guide: modprobe ocfs2_dlmfs mount -t configfs none /config mount -t ocfs2_dlmfs none /dlm o2cb_ctl

All, This is hopefully the final drop of the patches for adding global heartbeat to the o2cb stack. The diff from the previous set is here: http://oss.oracle.com/~smushran/global-hb-diff-2010-10-07 Implemented most of the suggestions provided by Joel and Wengang. The most important one was to activate the feature only at the end, Also, got mostly a clean run with checkpatch.pl. Sunil
