Hi Rambo,

I would not advise either of the above plans. This is yet another 
problem with boot-from-volume.

A better use of your time would be to split the original giant volume 
into the operating system part and the application data part. Make the 
application data part into a normal non-bootable volume and use a 
regular operating system image as your root/boot partition.

You can't build a palace on quicksand.

Best,
