Solaris 10 includes samba 3.0.x with zfs support. Sun backported zfs
modules from newer sun releases. If you were to download samba from
www.samba.org you would have to go with 3.4 or 3.5 for the zfs module.
In the short term, assuming you don't have Vista or Windows 7 clients
and aren't doing domain trusts the Sun bundled version of Samba should
meet your needs.
I did have some issues when switching from UFS to ZFS. ZFS ACL model is
a lot more in line with Windows than UFS ACL's were. With UFS, it
looked like potential mismatches between Windows and UFS acl's were
ignored. With ZFS, you are more likely to run into permissions being
enforced inappropriately- especially with MS Office documents. There
are various posts in this forum on Solaris 10 (some from me) that
address this.
You may want to set samba share parameters to include
vfs objects = zfsacl
nfs4: mode = special
nfs4:acedup = merge
nfs4:chown = yes
zfsacl: acesort = dontcare
You may also need to set ZFS permissions to allow the user to
read/write the following
a = read_attributes
R = read_xattr (exended attibutes)
c = read_acl
Although you can also set permissions via windows. You also want to
make sure that setting a file under solaris with e.g. "660" (ie. user
and group can read and write but no one else can ) doesn't end up being
interpreted by windows clients as "deny access to everyone even despite
rights granted to user or group."
I don't actually do quota checking in Windows. Free space info seems
OK. But I have several servers with autofs and symlinks under the samba
shared directories so I don't always expect samba directory info to be
correct. So this may be a cop out but you may need to setup a test
machine to verify for yourself.
There are a lot of features in ZFS that are big improvements over
UFS. Especially if you have RAID5 volumes- those are really easy to
destroy in UFS if you loose your raid configuration info on the server.

Hi,
I've recently moved our student fileserver from a Solaris 10 server
that was using UFS filesytems to a new Sun Cluster. As part of the
move I decided to employ ZFS for the filesystem so that I could take
advantage of some of ZFS's features. However, it now seems that
windows does not report the amount of space that the user is actually
using, or the amount of quota left, instead it reports the total
amount of space in use and free on the total filesystem. I'm currently
running and exceptionally old version of Samba (<3 !) and have been
planning to upgrade to the latest version of 3 prior to the start of
term. However, I'm concerned that this may be an inherant issue with
Samba and ZFS. Will any of the latest versions of Samba correctly
report a users usage and free space based on their quota or am I going
to have to look at moving all the data back to UFS to get quota
reporting working again?
Martin.
