How to change Logical Volume name
My kid did some magic with my Mac and somehow successfully rename the disk name to some weird name.

When I tried to rename it back, Finder refused it.
I tried with diskutil
tool but there is no command to change the LV name of a Logical Volume Family.
Dump from the diskutil command:

Does anyone know how to fix this? My macOS is 10.12.3 macOS Sierra
Two approaches:
Try using the Volume UUID instead of the name:
diskutil rename LVUUID newName
So, in your case, issue the command:
diskutil rename DF2B66E8-0534-430A-B9F6-5697E4E294B2 OSX
Change it in Get Info
Right click (Command Click) the volume and select Get Info (or press CommandII while selected). Then enter the new name in the "Name & Extension" field.
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"
