Hi all.
This is a second post since the first one seams not have got to the list.
I'm trying to run a OCFS2 filesystem over the DRBD layer.
Before trying with the OCFS2 i tested the system creating a LVM logical 
volume with the DRBD device and formated it with XFS. I could mount this 
files system on both machines with the role primary/secondary with no 
trouble.
After that i removed all the lvm configuration and changed my DRBD 
configuration so as to allow primary/primary. I formated the hole partition 
as a OCFS2 filesystem, started the cluster service but when i try to mount 
the filesystem i gottis error:

root at apolo1:~# mount -t ocfs2 /dev/drbd0 /clusterdisk
mount.ocfs2: Invalid argument while mounting /dev/drbd0 on /clusterdisk. 
Check 'dmesg' for more information on this error.

this is my DRBD status:
root at apolo1:~# /etc/rc.d/drbd status
drbd driver loaded OK; device status:

I'm on a Slackware system with this kernel version:
root at apolo1:~# uname -a
Linux apolo1 2.6.21.5-smp #1 SMP Tue Jun 19 14:52:25 CDT 2007 i686 Dual-Core 
AMD Opteron(tm) Processor 2210 AuthenticAMD GNU/Linux

Doing some research on the list i have found those two threads related to 
this issue:
http://lists.linbit.com/pipermail/drbd-user/2007-January/006346.html
http://lists.linbit.com/pipermail/drbd-dev/2007-January/000613.html

Please can you tell me it this still apply to my kernel version? Can you 
point me the way to solve this issue?

Tanks in advance for your attention,

Carlos
