A better qualification is to say "when people have bad disk full Btrfs experiences" the typical case is because data chunks have free space but metadata chunks don't. If metadata chunks are completely full, and there's no unallocated space to create more metadata chunks, the file system will ENOSPC and some really unpredictable things can happen including inability to delete files.

I just wanted to let you know that this post saved my bacon yesterday when the root fs ran out of metadata chunks while downloading the update packages and systemd decided it should roll over the logs at the same time. With over 30GiB free according to df I would not have known what to make of all these ENOSPC errors spewing from dmesg. A rebalance didn't work until I deleted a few old snapshots and then it took quite some time, but it did recover some 20GiB to "unallocated", so it should be a while before this happens again (I hope).
