Quotas is something you shouldn't expect to be reliable any time soon.
That isn't what Chris Mason says:
They are still problematic for some people. For instance there is an unfortunate interaction between quotas and snapshots, there was someone having issues on btrfs list recently where the btrfs-cleaner kernel thread would consume a whole core whilst quotas were enabled: http://www.spinics.net/lists/linux-btrfs/msg45652.html # I can confirm that getting rid of the quotas fixed the issue for me. # Just disabling quotas wasn't enough, I had to enable, delete all # qgroups, reboot because disable was hung on one of the filesystems, # then disable quotas. Now when btrfs-cleaner runs it doesn't # completely consume a core, I can see corresponding disk i/o, and the # process goes away after a reasonable amount of time. To give some context this person had 92 subvolumes, including snapshots. All the best, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC
