[cifs-discuss] Disk quotas with CIFS & ZFS

[Ross]

Not sure if this is the best place to ask about this.  I know ZFS doesn't have user quotas, but is there any chance something like this could be added to CIFS?

I'm trying to work out if ZFS is suitable for storing our users home folders on a windows network, without adding extra management overhead if possible.  With Samba on ZFS I believe it's possible to fire off a script to auto-create users home file systems.  I've not tested it myself, but the theory sounds fine.

I don't believe there is anything equivalent with ZFS and the Solaris CIFS server though.  Windows can create folders automatically for user profiles, but that's about all.  What I'd like is to be able to use ZFS and CIFS as the main storage for our windows network in as seamless a way as possible.

I think there are really two possible routes to take, neither of which are available yet:

a)  Automatically create filesystems for each user.  This would involve trapping the call windows makes to create a directory for the user profile and creating a filesystem instead.

b)  Allow per user quotas in ZFS / CIFS.

I've no idea how hard this would be, does anybody else think this would be a good thing to have?
