i am trying to mount / on a logical volume with reiserfs. my initrd appears to be loading all of the appropriate modules (lvm-mod, dm-mod, reiserfs) but i get the following error when the initrd exits and tries to mount /.

device-mapper: unknown block ioctl 0x5310
sh-2021: reiserfs_read_super: can not find reiserfs on device mapper (254,1)

is this related to reiserfs or lvm? or my initrd?
using:
lvm-2.00.07
reiserfs-3.6.9-37
suse-9.0
kernel-2.4.21-144-athlon

You likely are hitting a problem with the device numbering for DM devices. The kernel dynamically allocates major and minor numbers for the DM, so booting to a different kernel can renumber your DM devices. Have a look at the lvm2create_initrd script that's been posted on this list several times to see how I (and others) have handled this situation. It's also available here:

#2 lore raw

Hello,
I experienced also difficulties with / and lvm2.
configuration:
MANDRAKE 10.0,
kernel 2.6.3,
lilo 22.5.8,
reiserfs 3.6.11 ?
lvm 2.00.08

The message I have got is something like lilo does not handle device type 0x1f00

Can not ensure that it is the exact message and type.

I understood that the version of lilo I use can not handle lvm2 and reiserfs partition for / during boot ! And especially can not get boot image in /boot.

Shame :(

In reply to Garcia Pascal

My solution for this (so far) is to make a non-LVM2 /boot partition and store a kernel and initrd in that. You can then build everything else as a LVM partition. Perhaps when the available bootloaders become LVM2 aware we'll be able to do away with a seperate /boot, but for now it seems to be the best way to deal with it.

#6 lore raw

Hello
I do not know what the problem is.
May be the problem has nothing to see with lvm!
I reinstalled the system two times with the same problem. In fact there is a warning when configuration lilo at installation time.

As I did not have that much time to analyse and solve the problem (if I would have been able to), I just made a / reisefs partition, and the problem went away.

I have a remark on that, / partition in a logical volume without reiserfs (or a fs that can be resized without unmounting) is non sense for me, because one can not unmount / partition, and one of the interest of the lvm is to adapt the size of a partition when needed.

I have a spare disk and when I have some time and my General let me do it, I reinstall the system and write all the problems. May be this week-end.

Here is the test I have been doing. Sory but I have to translate the french message then they will bot be exact.
Installing Mandrake,
When partitionning I ask for personal, then for expert.
- hda1 : LVM for linuw.
- Add to vg rootvg
In root vg
- 1rst partition / 3000 mb reiserfs
- 2nd partition swap 1500 mb
- 3rd partition 15000 mb

rest of the vg unaffected.

All installation went well until stage : installation of boot manager. Then a window came saying
=================================
L'installation du programme d'amor�age a �chou�
pour la raison suivante
: Fatal: Sorry, don't know how to handle device 0xfe00
=================================

That means : The installation of the boot loader failed because of the following reason : Fatal ...

And of corse the system is not able to boot!
