I suspect when using more than zero the first chunk it wanted to balance

The patch is in branch dev/balance-limit in my git repos.
We can then implement the n-least-full as a synthetic

The limit filter applies last, the value of 0 means no limiting.

Strange, I'm able to consistently reproduce this on a

Does that mean the updated test passes successfully for you?

scrub was mostly about making sure the data match the

Just curious, the future online filesystem check, will that be part
of scrub, or another command. It seems like it would be common to
want a faster integrity check that doesn't have to read all of the
data as well.
