The one thing I would add is that when you try to rename the VG, it may complain of active volumes in it and bail out. I did this exercise: rename my *system* disk's VG from VG00 to KEPLER. This is done entirely within the LiveCD environment. The VG name is arbitrary, name it anything you prefer. In my system disk I have a separate /boot and a VG with /, swap, /var, /usr, /usr/local, /tmp and /home. **Boot with a LiveCD You cannot change the VG name on a running system disk. Trying to rename the VG when LVs are still active, results in an error saying that there are active LVs in the VG. Do "lvs" --notice that one of the LV Attributes (Attr) is "a" for active. **Turn off the swap partition The LiveCD mounts the swap image and doesn't let go of it. # swapoff -a # lvchange -an /dev/VG00/swapLV (type in your own device name) **Deactivate all LVs The LV name is whatever name is under the LV column. # lvchange -an /dev/VG00/<LV This is where you use the reference[1] to edit the initrd image file.
