FYI, there is plenty of free space (~150 GB).
It could be some corner case:
- filesystem is mounted with compress-force,
- one kvm process (the only writer to btrfs) writes to the btrfs
filesystem, via the virtual guest using a 220 GB qcow2 image file (lots
of writes) and a 7 GB qcow2 image file (very few writes).
