Good idea, although I'd argue this is potentially a huge problem if a large file system needed to be rebalanced (could take days or weeks) before removing a device. It'd likely fail in a real scenario by then. But here is the attempt: [root@f18v ~]# btrfs fi balance /mnt ERROR: error during balancing '/mnt' - No space left on device There may be more info in syslog - try dmesg | tail [ 5860.532696] btrfs: relocating block group 11070865408 flags 18 [ 5860.557268] btrfs: found 1 extents [ 5860.573295] btrfs: relocating block group 10996416512 flags 20 [ 5860.590275] btrfs: relocating block group 10694426624 flags 20 [ 5860.616739] btrfs: relocating block group 10576199680 flags 20 [ 5860.901766] btrfs: found 2690 extents [ 5860.923053] btrfs: relocating block group 9706930176 flags 9 [ 5863.197821] btrfs: found 4 extents [ 5864.066177] btrfs: found 4 extents [ 5864.086322] btrfs: 8 enospc errors during balance Chris Murphy
