Hey Mulyadi,

I think you're ahead of the current status of OpenSSI / Lustre support,:

http://wiki.openssi.org/go/Lustre

It's not clear to me if full Luster support it part of the roadmap for 1.9:

AFAIK, CFS is your only real option currently if you want the storage
to be managed inside the cluster.  And then you can add drbd
functionality for failover within the cluster.  And neither CFS nor
DRBD provide the requested funcitonality.

In theory you can create a separate Lustre cluster to export storage
to your openSSI cluster, but that's not the requested functionality
either.

fyi: I haven't built a openSSI cluster, but I follow it to some
extent.  I find the technology very interesting and way back when I
worked Tru64 clusters which were similar.

Good Luck
Greg
