Hi,
I have a problem installing LILO under a 2.6 kernel with LVM2 and DM.
Installing LILO under the 2.4 kernel with LVM1 works.
This is what I get when I run LILO under the 2.6 kernel:
# lilo
Fatal: Sorry, don't know how to handle device 0xfe02
Here are some details.
Distro: Gentoo.
Kernel: 2.6.0-test9-gentoo
System: HP Proliant DL360.
uname -a: Linux vdpas.vanvergehaald.nl 2.6.0-test9-gentoo #1
SMP Tue Nov 18 01:13:40 CET 2003
i686 Intel(R) Xeon(TM) CPU 2.80GHz GenuineIntel
GNU/Linux
I am using LVM2 in combination with device-mapper.
The machine has 2 internal disks connected to a Compaq Smart Array
controller, configured as a mirrored volume (RAID 1).
I started out installing Gentoo Linux on the machine, with the standard
2.4 kernel. While doing so, I configured the whole mirrored volume
for LVM1, and created several filesystems. It currently looks like this:
# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/vg01/lv03 1032088 160116 819544 17% /
/dev/vg01/lv04 3096336 1875480 1063572 64% /usr
/dev/vg01/lv05 3096336 58568 2880484 2% /var
/dev/vg01/lv06 3096336 32828 2906224 2% /home
/dev/vg01/lv07 3096336 32828 2906224 2% /appl
none 1036076 0 1036076 0% /dev/shm
/dev/vg01/lv01 126931 11341 109037 10% /boot
Then I compiled the 2.6-test9 kernel.
I created an initrd image file, installed LILO (while running the
2.4-kernel with LVM1), and whas able to make the machine boot
into the 2.6-kernel from the harddisk.
So far so good: it boots right from the LVM volumes. Great!
Now the problem:
LILO refuses to install under the 2.6-test9 kernel. :-(
When I run LILO, it says:
Fatal: Sorry, don't know how to handle device 0xfe00
The 0xfe00 device happens to be /dev/mapper/vg01-lv01, which is
pointed to by /dev/vg01/lv01. This is what the /dev/mapper directory
looks like:
# ls -l /dev/mapper/
total 0
crw-r----- 1 root root 10, 63 Jan 1 1970 control
brw-r----- 1 root root 254, 0 Jan 1 1970 vg01-lv01
brw-r----- 1 root root 254, 1 Jan 1 1970 vg01-lv02

brw-r----- 1 root root 254, 3 Jan 1 1970 vg01-lv04
brw-r----- 1 root root 254, 4 Jan 1 1970 vg01-lv05
brw-r----- 1 root root 254, 5 Jan 1 1970 vg01-lv06
brw-r----- 1 root root 254, 6 Jan 1 1970 vg01-lv07
According to the LILO documentation, the error means that LILO isn't
able to figure out the geometry of the drive. They suggest that I
should specify the explicit geometry of the drive in /etc/lilo.conf.
But I think this is not the case. I made an strace of a LILO run,
which shows an open() call failing with ENXIO. According to errno.h
this should be interpreted as "No such device or address".
But this is not true, as you can see:
# dmsetup info vg01-lv03
Name: vg01-lv03
State: ACTIVE
Tables present: LIVE
Open count: 1
Event number: 0
Major, minor: 254, 2
Number of targets: 1
UUID: L8LBZEZWcB331TgtdEvJEnZsoH0NyORT00000000000000000000000000000002
# dmsetup status vg01-lv03
0 2097152 linear
See also the relevant portion of the strace at the end of this email message.
Summary: I am able to install LILO under the 2.4 kernel with LVM1,
but I can't install LILO under the 2.6 kernel with LVM2 and DM.
No other problems. The 2.6 kernel boots and runs great.
Thanks for any advice.

Toon.
