Hi, I have a 11G btrfs file system where "btrfs-vol -b" get stuck in a loop. The "found 7 extents" messages and heavy disk io continues until I reboot: [26223.544037] btrfs: relocating block group 42079027200 flags 36 [26228.082740] btrfs: found 2457 extents [26228.104515] btrfs: relocating block group 41407938560 flags 1 [26228.423981] btrfs: found 124 extents [26229.514583] btrfs: found 124 extents [26229.544160] btrfs: found 7 extents [26229.812494] btrfs: found 7 extents [26230.453720] btrfs: found 7 extents [26230.733233] btrfs: found 7 extents [26231.383321] btrfs: found 7 extents [26231.652815] btrfs: found 7 extents ...
