Hello,
this is my scenario:
1)I've created a Pacemaker cluster with the following ocfs package on opensuse 
11.3 64bit
ocfs2console-1.8.0-2.1.x86_64
ocfs2-tools-o2cb-1.8.0-2.1.x86_64
ocfs2-tools-1.8.0-2.1.x86_64

2)I've configured the cluster as usual :
<resources>
      <clone id="dlm-clone">
        <meta_attributes id="dlm-clone-meta_attributes">
          <nvpair id="dlm-clone-meta_attributes-interleave" name="interleave" 
value="true"/>
        </meta_attributes>

          </operations>
        </primitive>
      </clone>

          </meta_attributes>
          <operations id="XenImages-operations">
            <op id="XenImages-op-monitor-120" interval="120" name="monitor"/>
          </operations>
          <instance_attributes id="XenImages-instance_attributes">
            <nvpair id="XenImages-instance_attributes-device" name="device"

            <nvpair id="XenImages-instance_attributes-directory" name="

            <nvpair id="XenImages-instance_attributes-fstype" name="fstype"

          </instance_attributes>
        </primitive>
        <meta_attributes id="XenImagesClone-meta_attributes">

          <nvpair id="XenImagesClone-meta_attributes-interleave" name="

          <nvpair id="XenImagesClone-meta_attributes-ordered" name="ordered" 
value="true"/>
        </meta_attributes>
      </clone>
</resources>

And all the resource are up and running

3)Then, using my SAN, I've configured multipath as following:

xenconfig (3600a0b8000754c84000002a04e031e5a) dm-0 IBM,1726-4xx  FAStT
size=19G features='1 queue_if_no_path' hwhandler='1 rdac' wp=rw
|-+- policy='round-robin 0' prio=3 status=active
| |- 3:0:1:0 sdd 8:48  active ready running
| `- 4:0:1:0 sdh 8:112 active ready running
`-+- policy='round-robin 0' prio=0 status=enabled
  |- 3:0:0:0 sdb 8:16  active ghost running
  `- 4:0:0:0 sdf 8:80  active ghost running
xenimages (3600a0b8000754ce3000003024e031dbf) dm-1 IBM,1726-4xx  FAStT
size=400G features='1 queue_if_no_path' hwhandler='1 rdac' wp=rw
|-+- policy='round-robin 0' prio=3 status=active
| |- 3:0:0:1 sdc 8:32  active ready running
| `- 4:0:0:1 sdg 8:96  active ready running
`-+- policy='round-robin 0' prio=0 status=enabled
  |- 3:0:1:1 sde 8:64  active ghost running
  `- 4:0:1:1 sdi 8:128 active ghost running

4)Then I've create the first partition on /dev/mapper/xenconfig.

5)format the partition as ocfs2
mkfs.ocfs2 -F /dev/mapper/xenconfig_part1
mkfs.ocfs2 1.8.0

6)this is the /etc/sysconfig/o2cb file
#
# This is a configuration file for automatic startup of the O2CB
# driver.  It is generated by running /etc/init.d/o2cb configure.

Could someone explain why?
I've made the same thing with ocfs2-1.4 and all works fine
