we recently started to look at a ZFS based solution as a possible
replacement for our DCE/DFS based campus filesystem (yes, this is
still in production here). The ACL model of the combination
OpenSolaris+ZFS+in-kernel-CIFS+NFSv4 looks like a really
promising setup, something which could place it high
up on our list ...
So we had our test system installed (build 133) and were happily
manipulating ACLs from Windows and also from our standard Debian
client using the Linux nfsv4 utilities ... transparently! We
were impressed ... until an applicaton issued a chmod and destroyed
the ACL.
We then of course found Paul Henson's proposal for aclmode ignore
and deny values
[http://mail.opensolaris.org/pipermail/zfs-discuss/2010/February/037206.html]
and the ZFS ACL thread he started in
http://mail.opensolaris.org/pipermail/zfs-discuss/2010-February/037863.html
.
So from this site: we very much support the idea of adding ignore
and deny values for the aclmode property!
However, reading PSARC/2010/029, it looks like we will get
aclmode=discard for everybody and the property removed.
I hope this is not the end of the story ...
