+1 for me on that too, having read matt's papers on dfly it does look
interesting, although i've been pretty happy with my freebsd nodes
once we got past 5.x.

too bad it's GPLv3. i'd be suspicious of using FUSE, although i
reckon it helps support multiple platforms. according to the roadmap
it looks like they are close to implementing code to guard against
split-brains and the like, that's a big one so hopefully they can work
funny - i know of a handful of products that are based on freebsd that
support clustered storage (NetAppGX, isilon), but at least zfs support
is coming along for freebsd, so hopefully it's only a matter of time
before someone develops a way to cluster ZFS heads together <grin>
as an aside, i was looking at gfs (google filesystem) workalikes.
this looked pretty interesting:
from a performance standpoint i'd be interested in seeing how it does,
but its interesting non-the-less...
