Description Winfrid Tschiedel 2007-01-31 06:42:31 EST
Description of problem:

On a Fujitsu Siemens Celsius R640 I installed a fedora core 6 (x86_64) 
on a SATA RAID ( Mirror ). The system has an ESB2. The RAID1 was configured
with Intel Matrix Storage Manager option ROM v5.6.1002ESB2. 
The system was upgrade to the actual patch-level ( Jan. 30, 2007 ).
To simulate an error on the RAID configuration, I removed one disc.
A reboot causes now a kernel panic.

Version-Release number of selected component (if applicable):


How reproducible:
Always, reproduced also on rhel 5 beta2


Steps to Reproduce:
1. Have System with ESB2 or ICH8R and configured RAID1 (isw)
2. Install fedora core 6 or rhel 5, update the system
3. remove 1 disc from the mirror - reboot the system
  
Actual results:

The decompresses the actual kernel ( 2.6.19-1.2896.fc6 ) and boots the kernel.
Red Hat nash version 5.1.19.0.2 starts :

After this I get the following errors :
device-mapper: table: 253:0: mirror: Device lookup failure
device-mapper: reload ioctl failed: No such device or address
Unable to access resume device (LABEL=SWAP-isw_bcegte)
mount could not find device '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc
setuproot: error mounting /sys
switchroot: mount failed
Kernel panic - not syncing

Expected results:

System boots also with one disc 
and if a second disc is added the mirror is syncronized


Additional info:
Same problem occurs on FSC tx200-s3 (ESB2),
but in this case LSI firmware is used and ddf1 raid

This is hardware RAID issue, not a dm-raid one, as far as i understand you. 
Trying to assign to kernel, but this may as well be a bios problem.

What i don't understand is
device-mapper: table: 253:0: mirror: Device lookup failure
you are running lvm mirror on top of the HW raid1?

If this is in fact a LVM mirror issue and unrelated to the RAID hardware, 
please flip the bug to lvm2 component (it may turn out to be an initrd issue 
as well, though).
Comment 2 Petr Rockai 2007-03-14 05:06:16 EDT
Sorry, now i see that you are using fake raid, not actual hardware raid. This 
may indeed be dmraid issue then, or initrd one.
