Rescue system unable to be booted via pxe
Last modified: 2007-11-30 17:07:35 EST
The rescue system is unable to be booted via PXE at the moment.
The anaconda installer is looking for a minstg2.img, while the cd only contains
a stage2.img file.
Symlinking the stage2.img file to minstg2.img is a workaround and makes anaconda
The PXE configuration for pxelinux:
append initrd=rescue_rhel5_i386/initrd.img rescue
ks=http://foo/rescue/ks_rhel5_i386.cfg console=tty0 console=ttyS1,57600n8r serial
The kickstart file:
network --device eth0 --bootproto dhcp
url --url http://foo/rescue/rhel5/i386
timezone --utc Europe/Berlin
How much RAM does the machine have?
After getting into the graphical installer, please switch over to tty2, grab
/tmp/anaconda.log, and attach it to this bug report.

I attached the bootlog from the rescue boot, while the image was symlinked.
It's fetching minstg2.img because you are using a serial console. Serial
implies text install, which is one of the criteria for using minstg2.img instead
of stage2.img. This combined with the url install method is why it's trying to
fetch from a remote system. If you are trying to have it use the CD for the
source of the stage2 image, either use the cdrom install method or just don't
use a kickstart file for this purpose.
Does this help explain the behavior you are seeing? I'm not sure if it
qualifies as a bug or not.

Mhm. Yeah. That makes sense.

Nah, I'm perfectly alright with it pulling the data from the remote server.
That's exactly what I'm trying to do, booting a remote machine in the
data-center into the rescue mode.

Well, trying the network URL given in the kickstart file is definitly no bug.
That is what I'm expecting.
The problem is that anaconda (when booting via serial) tries accessing
minstg2.img which is not available on the rescue-CD at the moment.
One can only get the rescue-CD to work after symlinking the stage2.img file to
the (non-existing) minstg2.img file.
