I can see similar behaviour with 3.14.2 - after 4 days, it's only 25% done: root 8382 2.1 0.0 17840 628 pts/1 D+ May04 124:12 \_ btrfs balance start /mnt/lxc1 -v # btrfs balance status /mnt/lxc1 Balance on '/mnt/lxc1' is running 611 out of about 2492 chunks balanced (612 considered), 75% left The reason I'm running balance here is that 3.15-rc* had the filesystem hanging for me when doing rsync (and sometimes hanging during snapshotting), so I've downgraded to 3.14.2 (no hanging so far). -- Tomasz Chmielewski http://wpkg.org
