JBOD configurations (multiple data directories) do not come into play with the garbagecollect command because partitions do not span across directories.
Another way of saying it is that the token ranges are mapped to specific disks so fragments of a partition (which hashes into a token value) will only ever be stored on the same disk. Cheers!
