I've got a Macbook Pro Retina (with the PCIe drive ‘blade’, instead of a traditional 2.5" laptop drive). I've recently upgraded the internal drive from 500GB to 1TB, and `dd`'d the old drive over the new one to retain my partition setup and Bootcamp partition.

Unfortunately, this didn't go well: for whatever reason, OS X wouldn't recognize, once I'd booted up on the new 1TB drive, that there was 500GB of new space available. It was showing up in Disk Utility as greyed-out space.

To aid in debugging this, I wiped out the Bootcamp partition entirely (I have backups. I intend to restore that later, once I've got the drive fixed up from within OS X.); and eventually, after getting fed up trying to get `diskutil cs resizeStack` to work, I `diskutil cs revert`'ed the boot volume entirely.

Now I have this situation:

    > diskutil list
    /dev/disk0
       #:                       TYPE NAME                    SIZE       IDENTIFIER

After trying to drag the single partition in Disk Utility from 500GB up to 1TB, and then clicking ‘apply’, the process appears to proceed, and complete; but as soon as the completion message appears in the bottom-right, the partition map reverts to what you see in the screenshot. It never succeeds in re-sizing to 1TB. (Here's the [verbose log](https://gist.github.com/ELLIOTTCABLE/feb53a127e1cc77d7b8a).)

(Attempting to do the same from the recovery partition's Disk Utility gives an ‘Error: could not unmount disk.)

At this point, all I want in the world, is to re-size the single partition on my drive from 500GB to fill the available 1TB of space. Once I succeed with this, I'll be able to convert it to a CoreStorage volume, encrypt it, partition for Bootcamp and such.

Please help!
