One of these ways is to improve the implementation of quota groups (qgroups), thus the "real size" of snapshots can be queried from the filesystem. The problem: copy on write works on a block basis, thus one block can be shared by multiple copies. So the question is: what is the "real" amount of bytes a specific file or file version consumes? This question is even harder to answer, if compression is used (compression is done block wise, if I am not mistaken). That's the primary reason, why I do not use and would not use btrfs' compression yet. With openSUSE 13.2 we might be in a better shape in the future... I suggest to close this as an enhancement request..... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
