Not sure if I undertand that you meant, here.

The filesystem is not fine, it caused btrfs balance to hang, whether
balance actually broke it further or caused the breakage, I can't say.
Then mount hangs, even with recovery, unless I use ro.
This filesystem is trash to me and will require over a week to rebuild
manually if I can't repair it.
Running check without repair for likely several days just to know that
my filesystem is not clear (I already know this) isn't useful :)
Or am I missing something?
