[Pacemaker] Pacemaker will not mount ocfs2

[Johan]

I've been following this http://publications.jbfavre.org/virtualisation/cluster-
xen-corosync-pacemaker-drbd-ocfs2.en tutorial on how to setup a pacemaker xen 
cluster. I'm all new to this so pls bear over with me.
The big problem is that when UI get to the pont where the filasystem should 
"automagically" mount, it doesn't. 

Here's my config:

node cluster01
node cluster02
primitive Cluster-FS-DLM ocf:pacemaker:controld \
        op monitor interval="15" \
        meta target-role="Stopped"
primitive Cluster-FS-DRBD ocf:linbit:drbd \
        params drbd_resource="cluster-ocfs" \
        operations $id="Cluster-FS-DRBD-ops" \
        op monitor interval="20" role="Master" timeout="20" \
        op monitor interval="30" role="Slave" timeout="20"
primitive Cluster-FS-Mount ocf:heartbeat:Filesystem \
        params device="/dev/drbd/by-res/cluster-ocfs" directory="/cluster" 
fstype="ocfs2"
ms Cluster-FS-DRBD-Master Cluster-FS-DRBD \
        meta resource-stickines="100" master-max="2" notify="true" 
interleave="true" target-role="Stopped"
clone Cluster-FS-Mount-Clone Cluster-FS-Mount \
        meta interleave="true" ordered="true" target-role="Stopped"
order Cluster-FS-After-DRBD inf: Cluster-FS-DRBD-Master:promote Cluster-FS-
Mount-Clone:start
order Cluster-FS-DLM-Order inf: Cluster-FS-DRBD-Master:promote Cluster-FS-Mount-
Clone:start
property $id="cib-bootstrap-options" \
        dc-version="1.0.9-74392a28b7f31d7ddc86689598bd23114f58978b" \
        cluster-infrastructure="openais" \
        expected-quorum-votes="2" \
        no-quorum-policy="ignore" \
        default-resource-stickiness="1000" \
        stonith-enabled="false" \
        last-lrm-refresh="1329823386"

I keep getting the:
 info: RA output: (Cluster-FS-Mount:1:start:stderr) FATAL: Module 
scsi_hostadapter not found.
in the /var/log/syslog

I've been googling around for a solution but all of them seem to fail for me.

any help is much appreciated

Thanks Johan
