Hi list, I have trouble understanding this, which doesn't really correspond to the wiki FAQ (so my question is hopefully not a FAQ ;-) :
# btrfs fi df / Data: total=74.01GB, used=72.77GB System, DUP: total=8.00MB, used=16.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=1.75GB, used=657.48MB Metadata: total=8.00MB, used=0.00 Some questions are : What are the "DUP" lines compared to the "non-DUP" ones ? If I can understand "Metadata" and "Data", what is "System" supposed to be ? Is there anyway to know how much space is consumed by any given subvolume or snapshots (for snapshots, "du" cannot tell how much they really consume, of course...) This is so clear in ZFS for example ;-) ...and such a mystery in BTRFS... I also have a question relating to quotas : I understand that per-subvolume quotas are not (yet ?) implemented, but is it possible to use the user quotas system with btrfs, i.e. mounting it with the "quota" option such as ol'ext2/3 did ? TIA, kind regards. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
