Quota questions

[Edgaras Lukoševičius]

I was fighting domain quota for a long time, too. And I was never really

and domain quota recalc is just one of them :)

After a long trial and error I ended up implementing XFS project quotas.

Single user quota is fine and simple, the group quota /for example domain based/ makes me unhappy.
