LVM creation in post installation
I would like to install LVM in my disk, because I found there is flexible in resizing.
My question is I have completed installation of OS and application, Now, I wish to change from devfs to LVM without erase my stuff in disk, is it possible to do that?
I heard that EVMS's snapshot can do it? Is lt true? Is EVMS a kind of LVM or just an application to create volume?
If snapshot is workable, then should I use additional disk to store the snapshot object?
Actually, how does it work?
There are so many question mark above my head, I hope someone help to solve the problem? TQ
