Certainly not while mounted read-write. While mounted read-only --
I'm not certain. Possibly.
In theory, it is possible, but I think that the safety measures in
`btrfs check` don't distinguish between the two cases, so in practice it
may not be possible.

Could you show the result of btrfs check --readonly on this FS? The
rest, below, doesn't show up anything unusual to me.
