Having major OCFS2 blues here... Still having issues maintaining a stable cluster. I've tried isolating the issue by getting an entirely dedicated ethernet switch for the OCFS2 cluster. I've tried shutting off all machines, and slowly bringing them back online. This sort of works. So far I have been able to get 2 nodes back online, but I don't know how long until they mysteriously reboot again for no reason.
What I'm currently up against is an Unknown code B o while mounting /dev/sdc on /raid2005. Check 'dmesg' for more information on this error. I check the syslog and I get [(mount.ocfs2,1388,0):dlm_join_domain:1857 Timed out joining dlm domain ] So I'm stuck because this particular server which won't mount is a key player in the cluster. Any suggestions would be greatly appreciated. Tony === [ 16.390699] Loading iSCSI transport class v2.0-870.
