ah, i tried
Code:
diskutil list
... your command gives out this...

First disconnect any other drives then run this command in Terminal.

Then you should see the normal drive brand name on top with the volume name below in Disk Util. After that just open Finder and select the drive name and hit enter then rename it to what you want.

Code:
diskutil cs revert /

Code:
diskutil cs revert /

That resulted in this

Code:
Started CoreStorage operation on disk1 OS X Yosemite
Switching partition from Core Storage type to original type
Reclaiming space formerly used by Core Storage metadata
Even though the disk is now fully reverted, you should reboot soon to re-mount your reverted disk from the actual original partition
Removing Physical Volume
Destroying Logical Volume Group
Remounting former Physical Volume as normal disk
Core Storage LV UUID: 3B335146-F493-431E-96B1-F3DA99BD4481
Core Storage disk: disk0s2
Finished CoreStorage operation on disk1 OS X Yosemite

and now my disk utility looks like this:

aaah, a reboot fixed it. didnt know it was necessry since your detailed step by step didnt mention it :)

now disk utility sais this:
https://www.dropbox.com/s/0r7dfbfyvcq3wlo/Screenshot 2014-10-28 11.06.38.png?dl=0 and terminal
Code:
diskutil cs list
gives out this
Code:
No CoreStorage logical volume groups found

i guess the logical group was created by filevault?

Yeah... sorry I did not mention the reboot. A logical volume is created by either FileVault or now with Yosemite a default install on newer machines creates a core storage volume. Both result in that odd looking business in Disk Util.

Glad you are all fixed up. :)
