How to change Logical Volume name
You should be able to rename the volume with diskutil if it is mounted:

diskutil rename "OS''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''';;;;;;;;;;;;;;;;;;;;     ]\[X" "OSX"




Booted to Recovery Mode, launch Terminal from the menubar > Utilities.

Enter df to check if the CoreStorage volume is mounted:

Filesystem                     512-blocks       Used Available Capacity   iused    ifree %iused  Mounted on
...
/dev/disk2                      132538512   30003784 102534728    23%   3750471 12816841   23%   /Volumes/OS''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''';;;;;;;;;;;;;;;;;;;;     ]\[X
...


If the volume is mounted

diskutil rename /Volumes/OS\' 


hit the tab key here to autocomplete the volume name and add "OSX":

diskutil rename /Volumes/OS\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\'\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\ \ \ \ \ \]\\\[X/ "OSX"
