[Ocfs2-users] fencing problem?

[Juan Antonio Cortés]

Hi,

I tried to configure ocfs2 upon drbd, primary-primary role. drbd stage was
ok, but when I start the cluster and format the ocfs partition, the peers
detach it disk and when I mount the FS on both nodes drbd goes diskless. I
used both ocfs2console and command line tools.

I don't know why is this happening, but It is supposed to be a DLM fencing
problem.

 the log shows like this:

troubles?
