Actually, yes, I start DRBD manually, because this is currently a test configuration which relies on OpenVPN for the communications between these 2 nodes. I have no order and collocation constraints because I'm discovering these software and trying to configure them step by step and make resources work before ordering them (nevertheless, I just tried to configure DLM/O2CB constraints, but they fail, apparently because they are relying on O2CB, which causes the problem I wrote you about.) And I have no OCFS2 mounts because I was on the assumption that OCFS2 wouldn't mount partitions without O2CB and DLM, which seems to be right :

root@Malastare:/home/david# mount -t ocfs2 /dev/drbd1 /media/ocfs/
mount.ocfs2: Cluster stack specified does not match the one currently
running while trying to join the group
Concerning the notify meta-attribute, I didn't configured it because it
wasn't even referred to in the DRBD official guide (
http://www.drbd.org/users-guide-8.3/s-ocfs2-pacemaker.html), and I don't
know what it does, so, by default, I stupidly followed the official
guide. What does this meta-attribute sets? If you know a better guide,
could you please tell me about, so I can check my config based on this
other guide?
And, last but not least, I run Debian Squeeze 3.2.13-grsec-xxxx-grs-ipv6-64.
Thank you in advance.
Kind regards.
PS: if you find me a bit rude, please accept my apologies; I'm working
on it for weeks following the official DRBD guide and it's frustrating
to ask help as a last resort and to be answered with something which
sounds like "What's this bloody mess !?!" to my tired nerve cells. Once
again, please accept my apologies.
