So if it happens again, first capture the above two bits of

It has a massive pile of enoscp related rework and I bet Josef would
like to know if the problem reproduces with that kernel. As in, just
change kernels, don't try to fix it with balance first.
Looks like 4.8 helped (running 4.8rc8 now).
With 4.7, after balance, the "used" value continued to grow, to around
300 GB, although used space shown by "df" was more or less constant at
130-140 GB:
# btrfs fi show /var/lib/lxd
Label: 'btrfs' uuid: f5f30428-ec5b-4497-82de-6e20065e6f61
Total devices 2 FS bytes used 135.40GiB <--------- was growing
devid 1 size 423.13GiB used 277.03GiB path /dev/sda3
devid 2 size 423.13GiB used 277.03GiB path /dev/sdb3
After upgrading to 4.8rc8, "used" value dropped, so hopefully it's fixed
now.
