Mac Pro, Yosemite 10.10.2 Can't rename LV (Logical Volume) Name:



I cannot change LV Name neither in Finder or via Terminal. The name looks strange, thanks to my 2.5 years daughter. I have no idea how she changed the name, but it happened. If I try to rename simply in Finder, the message is that I should use either smaller number of symbols or avoid using commas et cetera. This message appears even if I try to use a single symbol like 'd' as a new name.
Try to rename it issuing this command on the terminal as a privileged user:

diskutil CoreStorage rename (uuid of the logical volume) NewName
