Hi,<br><br>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.<br>
<br>I don't know why is this happening, but It is supposed to be a DLM fencing problem.<br><br> the log shows like this:<br><br><br>Oct 6 13:53:07 s3 kernel: block drbd0: Got NegAck packet. Peer is in troubles?<br>Oct 6 13:53:07 s3 kernel: block drbd0: pdsk( UpToDate -> Diskless ) <br>
