See here on how to convert a core storage drive to normal HFS+ volumes without data loss in just a few seconds (I’ve tested this a couple of times without ever seeing an issue!): http://awesometoast.com/yosemite-core-storage-and-partition-woes/

Unfortunately on that post, it seems he’s using only 1 drive, so it is “core storage” but not in a fusion drive.
See a Fusion drive here as a comparison, It’s not “revertible”.

XFS
Does not have the ability to shrink period. It can only grow. The only possible solution is to do a file backup using something like xfsdump, then recreate the filesystem. Or make the smallest partition possible when you first install, then grow after imaging.

Thanks for the info, I guess it’s the best way to go for XFS (for now).
