Re: btrfs quota issues

Thanks for your inputs. Another question I had was, is there any way to check what's the directory/file sizes prior to compression and how much copression btrfs did, etc? Basicaly some stats around compression and/or dedupe from btrfs. On Thu, Aug 11, 2016 at 12:13 PM, Duncan
