For what it is worth, we have a couple of these machines running ZFS to
serve out several fileyststems to a 300 node cluster/condor pool, and I
have been very impressed with this filesystem. The main issue when sharing
out to Linux clients was the limited support for ACL's on Linux and the
still experimental status of NFS V4 on Linux, but that was solved by
mounting with version 3 and noacl.
