[DRBD-user] Drbd ocfs2

[Pierguido]

Hi.
I'm pretty new in the world of cluster (so in the drbd and ocfs2).
I'm trying to setup a little cluster (2 hosts) with drbd 8
primary/primary and on the top ocfs2 fs.

I got this situation:

host 1:


cluster-1:/mnt# /etc/init.d/drbd status
drbd driver loaded OK; device status:
version: 8.0.4 (api:86/proto:86)

but when i write something in host 1 host 2 is not syncronized.
Till now i didn't install heartbeat and i saw the ocfs is using
something about heartbeat...can i use a ocfs2 fs without heartbeat?
In the syslog i see no errors.
Probably i still didn't understand well how this setup works.

Can anybody help me?
Thanks
