Subject: [Sisuite-users] Cloned clients won't boot from harddisk (Redhat RHEL 4.0)
We use si_getimage to extract an image from the golden
client,
and then we install another client using PXE-booting.
All
this works beautifully until the cloned client tries to
boot from its
harddisk, where this message appears:
"Error loading
operating system"
We booted a Live CD and installed a boot loader
on the
disk using Grub, and now this slightly modified
cloned client boots
correctly.
The error therefore seems to be that the
SystemImager
Master script doesn't write the appropriate boot
loader
record (or whatever it's called) to disk. However, I
can't
figure out where the Master script is performing this action,
so
maybe there's a subtle problem here related to newer
versions of various
other tools ? I wonder if the "parted"
command used in the Master
script is supposed to make the
disk bootable ? The Golden Client's
autoinstallscript.conf
seems to look OK:
<disk
dev="/dev/hda" label_type="msdos"
unit_of_measurement="MB">
<!--
This disk's output was brought
to you by the partition tool "sfdisk",
and by the numbers 4 and 5 and the letter Q.
-->
<part num="1"
size="6000" p_type="primary" p_name="-"
flags="boot"
/>
<part num="2" size="2048"
p_type="primary" p_name="-" flags="-"
/>
<part num="3" size="2047"
p_type="primary" p_name="-" flags="-"
/>
<part num="4" size="*"
p_type="extended" p_name="-" flags="-"
/>
<part num="5" size="*"
p_type="logical" p_name="-" flags="-" />
</disk>
We have a similar setup with an older SystemImager
3.3
and RHEL 3.0 server / Fedora Core 2 clients which
works
beautifully. The Master script on this older version
seems to
be virtually identical to the Master script
generated by Systemimager 3.4.1,
and the FC2 clients
are indeed able to boot from the cloned
disks.
QUESTION: Can anyone help making our disks bootable
while using
SystemImager ?
FYI, we're using the Systemimager 3.4.1 RPM packages
from
http://sourceforge.net/projects/systemimager/
on a
Redhat RHEL 4.0 server and clients (actually, the client
is currently
running the Centos RHEL 4.0 clone). The
kernel version on both is
2.6.9-5.0.5.ELsmp.
