Hi, What do people think about qutoas in general? Are they really useful? I know there is a GSoC proposal for a generic quota API, but would that be really useful for HAMMER with it's fine grained snapshots? I mean, would the historical data be accounted for that user as well or not?
And then, I don't think quotas would be widely used on anything other than a HAMMER filesystem, so that I would not mind to see a HAMMER-only quota solution. My usage scenario is a Fileserver with many users. One thing that comes to mind is to spend one PFS per user home directory. IIRC, HAMMER supports up to 2^16 PFS. In my case it is obvious that limiting the real diskspace used by each PFS would be a nice feature, not only in my case, but also imagine one PFS per vkernel or jail, which would give much stronger separation guaratees than what we have right now. I am probably putting this question towards Matt because he knows best about HAMMER... so how hard would it be to implement (soft) PFS disk space tracking and limitation? Regards, Michael
