Ocfs2 users - Dec 2011 - ocfs2 with RHCS and GNBD on RHEL?

Does anyone have OCFS2 running with the "Red Hat Cluster Suite" on
RHEL?

I'm trying to create a more or less completely fault tolerant solution with
two storage servers syncing storage with dual-primary DRBD and offering it up
via multipath to nodes for OCFS2.

I was able to successfully multipath a dual-primary DRBD based GFS2 volume in
this manner using RHCS and GNBD. But switched to OCFS2 because GFS2 was very
slow for file system commands.

I'm currently exporting the OCFS2 volume to the nodes via iSCSI but, from
what I've read, you can't multipath dual-primary DRBD over iSCSI without
the risk of data corruption.

I would appreciate any advice or a possible how-to for making OCFS2 work with
RHCS.

Thanks,
Michael
