Just wanted to chime in with the same thoughts. It's not immediately apparent what your requirements are (i.e what problem are you trying to solve). So any answer you get might not really fit your needs and in the end just cause you a problems. And then you'll hate us and say we all suck (j/k I hope :-) -a -- [EMAIL PROTECTED] mailing list
[gentoo-user] migrating to LVM
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) Command (m for help): p Disk /dev/hda: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1191215358108+ 83 Linux /dev/hda219131925 104422+ 83 Linux /dev/hda31926972962685630 8e Linux LVM Command (m for help): q arrakis ~ # arrakis ~ # fdisk /dev/hdb The number of cylinders for this disk is set to 59582.
