Rich,

Can you try the following please and then report back.

Setting failmode to continue might let you continue a removal.
zpool set failmode=continue what_is_it_rigatoni?

This should be inherited by effected drives.
zfs set checksum=off what_is_it_rigatoni?

Remove the said effected files at this point.

Turn your failmode back to its default state which is "wait" and then turn 
your checksum back to on state or whatever you had it at previously.

zpool clear what_is_it_rigatoni?

zpool scrub what_is_it_rigatoni?

We will wait for you here...
