OSX Yosemite Logical Volume Group - FIX!

Hey guys,

For anyone wondering or concerned about why, when entering Disk Utility, the SSD name has been changed and you now see Macintosh HD and Macintosh HD below. The one above is listed as a Logical Volume Group with an "online" status while the one below that is your physical HDD (so normal as with previous OS's.

I must note that I do not have any recovery partition when holding option when booting (after installing straight onto Mavericks, nor when making my own bootable copy).

However, I did find a way to fix the Hard Drive name issue and revert it back to original format (I did find this fix online, and it has worked for me).

I included pictures below as well.

First one shows original Yosemite SSD name change (from Apple SSD to Macintosh HD with 18.9MB available)

Second shows your normal HHD name unchanged.

Go to Terminal and enter the following:

diskutil cs list

then you will see a bunch of volumes jump up

enter: diskutil cs revert "UUID"

under "UUID", enter the the Logical Volume code number without brackets.

Do not copy and paste it from terminal into your new terminal line. Write it out.

Hit enter and it will ask to reboot your Mac.

Once, rebooted, your old SSD/HDD name with reappear as in Mavericks.

My entire terminal line is shown in the picture attached.

Either way (SSD name changed or reverted) did not changed how the system performed. Everything is running as it should.

Final result shown in last picture!

Hopefully this is just a bug that Apple will fix.

Please ignore the DiskMaker drive (I was making a bootable copy on my external!!)
