Subject: RE: [Sisuite-users] Can System Imager deal with LVM yet?
Brian, thanks for finally clearing that up.
I went ahead
and came up with my own solution to this problem; however
this is a single
hangup that I cant seem to get past; if anyone has ANY
suggestions I would be
forever in their debt as I have spent so much
time trying to make this thing
work:
I am using SystemImager
to auto-install about 500 different
machines, some of them are CentOS; as you
can Imagine I want to automate
the installation of the bootloader; so I wrote
a 2 scripts to accomplish
this task. Why two? Because some of the machines
are IDE, and some of
them are SATA, and I need to be able to use the same
disk image on both
of the drive types. Here is the first bash
script:
if grep -q sda /proc/diskstats
then
TYPE="sda1"
MOUNT1="/dev/sda1 /a/boot"
MOUNT2="/dev/sda3 /a"
else
TYPE="hda1"
MOUNT1="/dev/hda1 /a/boot"
MOUNT2="/dev/hda3
/a"
fi
mount $MOUNT2
mount
$MOUNT1
MOUNT3="proc /a/proc -t proc -o
defaults"
mount $MOUNT3
MKSYS="-p
/a/sys"
MOUNT4="sysfs /a/sys -t sysfs -o
defaults"
mkdir $MKSYS
mount
$MOUNT4
MOUNT5="/dev /a/dev -o bind"
mount
$MOUNT5
echo "mount $MOUNT2"
echo "mount
$MOUNT1"
cp /sbin/grubinstall
/a/sbin/grubinstall
chmod 755
/a/sbin/grubinstall
chmod +x /a/sbin/grubinstall
chroot /a /sbin/grubinstall
exit 0
What this does is determines
whether the drive is SATA or IDE by looking
at diskstats, if it is SATA, it
mounts /dev/sda1 & /dev/sda3, if it is
IDE, it mounts /dev/hda1 &
/dev/hda3, it also creates and mounts all of
the auxillary filesystems (proc,
sys, dev) The next script which I run
in the CentOS environment via chroot
is:
TYPE=
SUBS=
if
grep -q sda /proc/diskstats
then
TYPE="sda1"
SUBS="s/hda/sda/g"
else
TYPE="hda1"
SUBS="s/sda/hda/g"
fi
grub-install --no-floppy --recheck
/dev/$TYPE
sed -i "$SUBS"
/boot/grub/menu.lst
echo
"sed -i $SUBS /boot/grub/menu.lst"
sed -i "$SUBS"
/etc/fstab
echo "sed -i $SUBS /etc/fstab"
sed -i
"$SUBS" /boot/grub/grub.conf
echo "sed -i $SUBS
/boot/grub/grub.conf"
sed -i "$SUBS"
/etc/grub.conf
echo "sed -i $SUBS
/etc/grub.conf"
ls "ls -l /etc/grub.conf /boot/grub/grub.conf
/boot/grub/menu.lst"
exit 0
By the way /a is the ROOT of the hard
drive (freshly imaged) and /a/boot
is the boot partition of the hard drive
(freshly imaged).
This script again enumerates the type of hard disk
attached to the
system, installs grub on /dev/hda1 or /dev/sda1,
modifies
/boot/grub/menu.lst /boot/grub/grub.conf /etc/fstab
/etc/grub.conf
sda>hda hda>sda and so
forth.
Everything actually
works fine; grub is installed; the files are
all modified
appropriately.
The issue comes
when the newly imaged system comes up. The first
time the system boots up;
grub is still configured to boot with
root=/dev/sda3; even though NONE of the
configuration files mention
anything about /dev/sda3. However if I hit 'E'
and modify the 'kernel
...' line in the grub editor from the bootloader, and
allow it to boot
up; the system boots up
normally.
The STRANGE part; is
that after the first time it boots off of
/dev/hda3; grub suddenly starts
using that EVERY time the system boots;
but I cant figure out why I have to
first manually change it; and then
reboot before it will
work.
Its almost like the
CentOS boot process 'fixes' whatever is
wrong with grub; the first time it
boots after I run my crazy script on
it; but I cant figure out what process
during the boot is doing it; or
what else I need to do to ensure trouble free
auto-installation of
CentOS.
Any advice anyone can give me would be
wonderful.
Thanks,
-Drew

I'm afraid what you
are attempting is currently not a supported
configuration. Disk type
independence is my next priority after getting
the current udev and uyok
code, that is currently in the development
trunk, released as
stable.
