There's a thread started on the Samba-Technical mailing list that has some
discussion regarding cluster filesystems. I'm learning fast, but I'm not
the right one to answer this:
http://lists.samba.org/archive/samba-technical/2004-December/038326.html
An excerpt:
The other network-like filesystems - Lustre, SANFS, GPFS, and RedHat's
GFS do differ a little.. They differ in that they would attempt
stricter posix semantics and therefore view themselves as "cluster"
rather than "network" filesystems (an odd distinction ... why shouldn't
a network filesystem simply consider "cluster" in effect a mount option
which would optimize for higher performance to nearby hosts in the
cluster and stricter POSIX file semantics rather than relaxed "nfs file
semantics"). If they had a good standards story with the IETF and were
inkernel in 2.6, perhaps no one would care, but it seems odd - when you
can make AFS or CIFS or NFSv4 do the same with rather more trivial
changes.
Somehow I think that the above doesn't quite capture what GFS is all
about. I'm not trying to start a flamewar, but I'd certainly like to see
someone provide a clearer explanation than I could do.
