Played with corestorage, missing 121g now

Help!

Late 2013 iMac 1TB fusion drive 10.10.2

So I worked out my bootcamp drive didn't have enough space assigned to it, and I've been trying to resize it without formatting it (I've given up on that)
One of the methods I came across involved resizing the corestorage of the mac HD to free up space, then expanding the volume in windows partition. However, once I'd resized it it wasn't accessible in windows.
Erasing the bootcamp partition in disk utility, it crashed and now the partition is there when using diskutil cs list, but disk utility won't pick it up in the GUI.
The hard drive in the GUI is showing the full 1TB fusion drive, but the Mac HD partition is capped at 728g and I can't seem to resize it anymore.

disk0s2 is the old bootcamp partition and diskutil won't let me reformat it, or delete it to try and merge it back in with the OSX partition

Anyone have any thoughts on how to fix this without burning everything and starting over again?
I want to get my drive back to normal, and then repartition using bootcamp giving myself a larger windows drive

You cannot resize a core storage volume like that is Disk Utility. There is a way to do it from Terminal, but it is a real hassle. You can read about it here.

What I would do it just clone it off and nuke then start over. You can do that by a command-option-r boot to Internet recovery. Once the globe is done spinning and you are in recovery, go to the Utilities menu and launch Terminal then enter the command below. That will kill the Fusion drive.

diskutil cs delete "Macintosh HD"

Then quit Terminal and start Disk Utility. You will get a popup message asking if you want DU to fix the Fusion drive. Tell it yes then wait until it is done. Now reboot to your clone and copy everything back.

Yeah, those terminal commands to manipulate the corestorage were what got me into trouble, guess I'll just clone off and kill. Cheers
