[Ocfs2-users] problem mounting ocfs2: heartbeat

[Sunil Mushran]

I will recommend reboot to cleanup any processes and extraneous mounts.

Then:
1. service o2cb start

lsmod should show the modules (only ocfs2 will not be there).
mount should show /config and /dlm.
ls /cluster/config/OCFS2CLUSTER/node  should show all the nodes in 
cluster.conf

2. mount
However this time strace it.
strace -ff -o trace.txt  mount -t ocfs2 /dev/hda4 /mnt
