Subject: [linux-lvm] LVM2 full disk & Grub
Date: Thu Feb 12 18:27:01 2004 [thread overview]
Message-ID: <402C0BF4.3000102@caltech.edu> (raw)
When I was going to install a full-disk LVM2 PV on my hard disk (not for
the root partition) with grub installed, I had very bad experience. I
searched the internet for possible warnings. All I got were 1. LVM1 was
known to be "unfriendly" to boot loader when the full disk is created as
one PV. and 2. LVM2 solves this problem by allowing the label sector to
be any of the first 4 sectors in the disk.
However, grub needs more than 3 sectors (in my system, 16 sectors),
which still conflicts with LVM2 when the full disk is used. So if you
happen to want to use LVM2 and grub in the same disk, you have to create
some partitions... NOT the full disk.
I don't know why I couldn't find this kind of information on the
internet or grub manual or LVM howto. In case there are also other users
as "careless" as me, my this post might be useful.
By the way, is there an LVM2 howto available somewhere?
