I'm using BTRFS on a Fedora 20 server. My kernel version is 3.17, and my BTRFS version is v3.17. My pool is composed of 2 identical 3TB drives; Some details on my system:
#btrfs fi show > Label: none uuid: 4f4b4c32-dc58-4288-a0d1-98db185dd429 > Total devices 2 FS bytes used 101.25GiB > devid 1 size 2.73TiB used 103.03GiB path /dev/sdc > devid 2 size 2.73TiB used 103.01GiB path /dev/sdd > Btrfs v3.17 Which is consistent; I have the two 3TB drives, each actually reporting 2.73TB. The 103 GB is interesting though, see below: #btrfs fi df . > Data, RAID1: total=102.00GiB, used=101.13GiB > Data, single: total=8.00MiB, used=0.00B > System, RAID1: total=8.00MiB, used=16.00KiB > System, single: total=4.00MiB, used=0.00B > Metadata, RAID1: total=1.00GiB, used=118.70MiB > Metadata, single: total=8.00MiB, used=0.00B > GlobalReserve, single: total=48.00MiB, used=0.00B Why am I only getting 102GB of data space? Google presented me a bunch of similar problems, but all of the ones I looked at were 1) running out of either meta or data space, 2) using devices of different sizes, or 3) needed to re-balance the pool (Normally resulting from either 1 or 2). My problem doesn't seem to match any of those scenarios, and my google-foo can't seem to get me any different suggestions. Are there any BTRFS gurus on this list that might be able to help? _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
