Description Alexander Shiyan 2006-04-24 18:34:30 UTC

Description of problem:

Currently I use initial FC5 kernel-smp package(2054), it work fine with my
motherboard ASUS P5WD2 with onboard Intel RAID. Because initial kernel does't
work with NVIDIA drivers, I want to upgrade to kernel-smp package from updates
(it is 2080 & 2096-builds). But it hung system on kernel init. Probably
device-mapper is broken in these kernels. Last messages on console is:
device-mapper: dm-stripe: Target length not divisible by chunk size
device-mapper: error adding target to table
device-mapper: reload ioctl failed: Invalid argument
Unable to determine geometry of file/device /dev/mapper/isw_bgchejihdh_HomeRAID0.
...
And halt with kernel panic on mount /dev/root and so on...

I think device-mapper is broken between 2054 and 2080 builds, because
on 2054 it is work fine:
[root@shc /]# /sbin/dmsetup table

Version-Release number of selected component (if applicable):
Linux shc.home 2.6.15-1.2054_FC5smp #1 SMP Tue Mar 14 16:05:46 EST 2006 i686
i686 i386 GNU/Linux
Kernels 2080 and 2096 are broken.

Additional info:
Disks in RAID is two identical new SATA-2 SAMSUNG HD080HJ.
I may provide additional info if need.

Comment 1 Alexander Shiyan 2006-04-27 08:17:46 UTC

I found one patch in kernel git-tree with patch for dm-stripe. This patch contain
this check. I think, it is incorrect patch and it must be removed (or modified)
from kernel...
http://www.kernel.org/git/?p=linux/kernel/git/stable/linux-2.6.16.y.git;a=commit;h=8ba32fde2c5be52865b2fd7e5e3752a46971fabe
Any comments?

Comment 2 Johannes Engel 2006-05-02 08:13:14 UTC

The dmraid-part of that is already fixed (thanks to Heinz Mauelshagen, see bug
#186842). The dmsetup-part is still open.

Comment 3 Alasdair Kergon 2007-01-10 16:23:20 UTC

kernel patch was correct - userspace dmraid needed fixing - an fc5 update perhaps?
