thank you for info. My idea was to try to replace my GPFS setup, that uses one
disk array (several LUNs) and three front-ends. GPFS is exported via Samba.

So I think about Lustre OSS and MDS to run on those three front-ends, but to
be able to export Lustre via Samba, I would need Lustre mounted on at least
one of the front-ends for Samba backend.
