[Ocfs2-users] Replication not works

[Marcos E. Matsunaga]

Yohan,

Can you run the commands below on the device you're trying to mount on
both nodes? If possible, format the partition before running them.

# debugfs.ocfs2 -R "stats" /dev/sdXX |grep UUID:
# debugfs.ocfs2 -R "stats" /dev/sdXX |grep Slots:
# debugfs.ocfs2 -R "slotmap" /dev/sdXX

Also, make sure you have the same /etc/ocfs2/cluster.conf and
/etc/sysconfig/o2cb on both nodes (copy from t1 to t2 to make sure they
are exactly the same).

Can you try the following:

# /etc/init.d/o2cb online
# mount /dev/sdXX <mountpoint>

If it fail, please, copy about 10 lines before first ocfs2 message from
/var/log/messages from both nodes and send it to me.
