Hi Michal, Kristal Pollack did a paper on distributed quotas that represents one possible approach for enforcement in the case where clients are untrusted: http://ceph.newdream.net/publications/quota-voucher-paper.pdf There is also the recursive accounting in the the MDS that in theory could facilitate subtree quotas. It already implements the accounting half of the problem, but the implementation of enforcement would be tricky.
