well, bot what if I would have keep my existing pool on these disks? ;-)

On the other hand, it's a mirror, and not too heavylu used, so I can remove 
second disk, clean it up, add it back, resilver, then do the same on the first 
one;

however, it seems to be a bit more generic problem: stale pool referring 
no-longre-accessible devices seem to be unclearable...
