^^^^^^^^^^^^^^^^^^^^^^^^
This is what I was alluding to. You could have started a -dusage balance
*before* the scrub so that one or several data chunks get freed.
Balancing metadata when you're out of space accomplishes nothing and only
will very likely fail, just as you saw. You have ~90GB usable space, but
that space is spread over chunks with low utilisation.
