I'm looking for a reasonably HA NFS solution (ie. a "NAS" nowadays) which
will support ACLs on NFS v3 (as well as the usual redundancy, VLANing,
GigE, etc.).  This is for Solaris and Redhat NFS clients, which both
support the "almost POSIX" NFS ACLs (different than those of NFSv4).

A company called CDS gave me the runaround for a while, making it look like
the NS700 would do this (or telling me I should buy one from them to try it
for myself {8^).  It doesn't.  In fact, neither EMC nor Netapp even pro
vide
NFSv4 ACLs as of a couple of months ago.

I've been looking at Consensus/Raidzone's Gangstor.  Anything else?

Thanks...

Well if you find one do post it.  As far as I know the only way to get
ACL's over NFS is with like OS.  Solaris to Solaris has been able to
do it for a long time but not many use Solaris as enterprise NAS.

As for NFSv4 don't bet the farm just yet.  It looks like some
questions are arising regarding the return requirement for certain
calls that may effect ACL's.  I don't know the details but it's been
something of a debate for a few weeks now.  I thought ACL's were part
of the spec but it may be an implementation issue.

I've had no difficulties mixing Solaris and Redhat Enterprise 3 clients and
servers (at least so far), but that's the only mix I've tried.  Noteworthy
is that Fedora Core 2 seems to lack ACLs in at least the NFS client; I've
not tried serving from Fedora yet.

If someone built a NAS around Solaris, I'd certainly check into it.  I like
Solaris.  As yet, though, I've not found anything that'll do what I want
beyond the Raidzone cluster (which is built around Linux).

And I would like options.  I may have found something, but we'll see.  I've
been strung along before (as I wrote earlier).

ACLs are, at least when I last checked, "recommended" in NFSv4.  That means
that both Netapp and EMC can call their products NFSv4 w/o supporting ACLs.
A shame...although if the specification is as yet incompletely defined, I
can understand it.

There's no standard NFSv3 ACL support, there's at least a Solaris
protoco for which Linux patches exist and an IRIX protocol (which
actually is xattrs for NFS over which you can implement ACLs).

You'll probably want the Solaris one so you should looks for various
Linux-based applicancee.  In fact any box running RH AS3 or SLES8/9
should do it.

Might also be a good thing as NFSv4 ACLs are a rather stupid spec and
map badly to the common Posix-ACL (*)

(*) well, the various implementations modelled after the last Posix
1003.1e drafts..
