[gentoo-user] migrating to LVM

[Thufir <hawat.thufir@gmail.com>]

I have a working gentoo install which I don't want to muck with too much, 
except to change over to LVM.  I understand that I can use dd so that 
everything will be in a LVM, but I'm unclear on the outline.  The LVM is 
created, the root partition is copied over to the LVM, then grub, fstab 
and initrd and edited to reflect the changes?


arrakis ~ # 
arrakis ~ # fdisk /dev/hda

The number of cylinders for this disk is set to 9729.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
