Hi, Two days ago I decided to throw caution to the wind and convert my raid1 array to raid6, for the space and redundancy benefits. I did # btrfs fi balance start -dconvert=raid6 /media/btrfs Eventually today the balance finished, but the conversion to raid6 was incomplete: # btrfs fi df /media/btrfs Data, RAID1: total=693.00GB, used=690.47GB Data, RAID6: total=6.36TB, used=4.35TB System, RAID1: total=32.00MB, used=1008.00KB System: total=4.00MB, used=0.00 Metadata, RAID1: total=8.00GB, used=6.04GB A recent btrfs balance status (before finishing) said: # btrfs balance status /media/btrfs Balance on '/media/btrfs' is running 4289 out of about 5208 chunks balanced (4988 considered), 18% left and at the end I have: [164935.053643] btrfs: 693 enospc errors during balance Here is the array: # btrfs fi show /dev/sdb Label: none uuid: 743135d0-d1f5-4695-9f32-e682537749cf Total devices 7 FS bytes used 5.04TB devid 2 size 2.73TB used 2.73TB path /dev/sdh devid 1 size 2.73TB used 2.73TB path /dev/sdg devid 5 size 1.36TB used 1.31TB path /dev/sde devid 6 size 1.36TB used 1.31TB path /dev/sdf devid 4 size 1.82TB used 1.82TB path /dev/sdd devid 3 size 1.82TB used 1.82TB path /dev/sdc devid 7 size 1.82TB used 1.82TB path /dev/sdb I'm running latest stable, plus the patch "free csums when we're done scrubbing an extent" (otherwise I get OOM when scrubbing). # uname -a Linux dvanders-webserver 3.10.1+ #1 SMP Mon Jul 15 17:07:19 CEST 2013 x86_64 x86_64 x86_64 GNU/Linux I still have plenty of free space: # df -h /media/btrfs Filesystem Size Used Avail Use% Mounted on /dev/sdd 14T 5.8T 2.2T 74% /media/btrfs Any idea how I can get out of this?
