Much to my surprise, it appears you can't force a scrub to start
immediately, or even to be the next one in the queue. :/ I think you can
hack around it with the correct combination of scrub settings; maybe one of
the more experienced cluster admins can tell you. (Something about turning
down the scrubs allowed to zero and the scrub intervals to very large
numbers? Then telling it to scrub the one you want and increasing the
number of allowed scrubs to 1?)

Anyway, can you submit a ticket for that feature? It would be pretty useful.
