Would you mind sharing your experience, maybe in the private E-mail. I
am especially interested in the platform you have used (as in AIX or
Linux) and underlying storage configuration (as in directly attached vs.
separate file system servers).

I am running few small AIX clusters in the lab using GPFS 3.1 over iSCSI
and so far was fairly pleased with that.

However, OP's point was that ZFS has inherent cluster abilities, of
which I have found no information whatsoever.
