Hello,
I'm running Debian stable on a custom 2.6.27.3 kernel. So far, whenever I
try
to start the cluster service, it throws a "o2cb_ctl: Unable to access
cluster
service Cannot initialize cluster" error. I have compiled ocfs2-tools 1.4.1
from source, and have tried ocfs2 both as modules, and compiled into the
kernel. As of now, I have been unable to get the cluster service started.
Currently, ocfs2 is compiled into the kernel, and the o2cb init script does
not run on startup:
root at debian1:~# /etc/init.d/o2cb start
Mounting ocfs2_dlmfs filesystem at /dlm: OK

Is configfs mounted (at /sys/kernel/config)? Is sysfs mounted? If configfs is *not* mounted, can you run 'sh -x /etc/init.d/o2cb start' and send us the output? That way we know why it isn't mounted. OTOH, if it is mounted, we want the strace(1) of o2cb_ctl.> root at debian1:~# sudo cat /etc/ocfs2/cluster.confWhy do you need sudo to cat this file? Are you not running with root privileges?
