Oh yes, it helps a great deal. Thank you very much. This is what I
get from /proc/lvm/VGs/vg00/LVs/lv01. "lv01" is the name I gave to
the root lv, but having a little more experience now I may change it
to simply "root" or "rootfs" as this makes things a lot more clear
when looking at the device entries.
My entry for lv01 (not currently mounted) says this:
# cat lv01
name: /dev/vg00/lv01
size: 12288000
access: 3
status: 1
number: 0
open: 0
allocation: 0
device: 58:00
So using your example then this would work out to a major:minor
number (in hex) of 3a:00, this then would go into my grub.conf
thusly (as I understand your instructions):
title Red Hat Linux (2.4.18-4) lvm root file system
root (hd0,0)
kernel /vmlinuz-2.4.18-4 ro root=3a00 ramdisk_size=8192
initrd /initrd-lvm-2.4.18-4.gz
instead of:
title Red Hat Linux (2.4.18-4) lvm root file system
root (hd0,0)
kernel /vmlinuz-2.4.18-4 ro ramdisk_size=8192
root=/dev/vg00/lv01
initrd /initrd-lvm-2.4.18-4.gz
Have I got this right now?
