You were absolutely correct to be rude.

A pragmatic fix would trigger read-only failure mode at 90% usage of the mount as a whole, with all subvolumes.

Thanks!

And you know what, that's a great idea.

The more practical advice is to resize hard partitions down by 5-10%.

I have a loopback mount on an fallocate file with a btrfs filesystem inside of it at work. I'm using send/receive to make sure there is hope of recovery.

I wrote this several years ago.
