Red Hat Bugzilla – Bug 142622
Fedora core 3 can not boot from system disk after installation
Last modified: 2007-11-30 17:10:56 EST
Description of problem:
The problem is related to kernel module load sequence by anaconda.
I have 4 SATA hard drives on my PC, two connected to motherboard
directly and 2 others are conncted through Promise SATA raid card.
while only the primary SATA hard drive directly connected to
motherboard is bootable.
When FC3 anaconda begins installation, it first load sata_promise,
and then load ata_piix(wrong sequence!!). So /dev/sda and /dev/sdb
are wrongly assigned to two hard drives connected through peripheral
Promise SATA card, FC3 operation system is then installed to /dev/sda
which is not bootable. /dev/sdc and /dev/sdd are then assgined to two
hard drives directly connected to motherboard(ata_piix module).
After machhine installed successfully, it just can not boot.
If anaconda can change the sata drive load sequence, like:
the driver module for SATA interfaces motherboard loads first.
the driver module for peripheral local SATA interface load second,
Then the problems will go away at once.
If there is a place|section, like in ks.cfg or anaconda.conf, that
we can specify the above "kernel module loading sequence" for initial
installation? does anaconda respect /etc/modules.conf
or /etc/modprobe.conf(FC3) during installation?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. find a machine, like HP workstation xw4100 or xw4200, with 4 sata
hard drives, two connected to motherboard, and two others through
promise SATA card.
2. begin normal installation in text mode and it will be
successfully installed, check the /tmp/anaconda.log to have a look of
the module load sequence.
3. reboot and now the machine just can not boot.
can not find FC3 operation system installed.
machine should boot.
The driver load order is determined by PCI ordering which ends up
being machine and even BIOS dependent. You can change the ordering of
the drives for boot loader purposes by going into the advanced boot
loader screen and changing the drive order.
