How does that work? As near as I can figure, you need to have all the sstable files from all nodes in a rack on disk. Most will be discarded on "nodetool cleanup", but I would expect it to have to rewrite all the files due to the new token range.

If you're not using vnodes, then you need all of the sstables from the previous $RF nodes in the ring. So with RF==3, it will briefly have about treble the amount that it will finally carry.
It's a lot of temporarily wasted disk space for sure, but now you're in full control of how you get the data there
