Description Jarkko 2007-02-19 01:42:55 UTC 
Description of problem: dmraid stopped from working after changing kernel to
kernel-xen. Worked with Fedora 7 Test1 kernel.

Version-Release number of selected component (if applicable):
kernel-xen-2.6.19-1.2898.2.3.fc7

How reproducible: Always (done twise).

Steps to Reproduce:
1. get Fedora 7 Test1 CD
2. install using dmraid
3. yum install kernel-xen + reboot using the xen kernel
  
Actual results: /dev/mapper/ does not contain the raid devices anymore.

Expected results: /dev/mapper/ should continue to contain the raid devices.

Additional info: I _only_ changed kernel to kernel-xen, so I am 100% sure that
"yum install kernel-xen" broke this.
Comment 1 Jarkko 2007-02-19 01:48:44 UTC 
- Working kernel: kernel-2.6.19-1.2914.fc7

- Same issue happens also with: kernel-2.6.20-1.2932.fc7 (see bug #229158)
Comment 2 Jarkko 2007-02-25 10:45:46 UTC 
I extracted /boot/initrd-2.6.19-1.2898.2.3.fc7xen.img and added to "init":

-------------------------------------------------------------------------------
rmparts sdb
rmparts sda
dm create ddf1_4c534920202020201000005500000000330a535300000a28 0 974608384
mirror core 2 131072 nosync 2 8:0 0 8:16 0
dm partadd ddf1_4c534920202020201000005500000000330a535300000a28
-------------------------------------------------------------------------------

...between lines "mkblkdevs" and "resume LABEL=swap".

Then I replaced /boot/initrd-2.6.19-1.2898.2.3.fc7xen.img with my modified
version and rebooted with 2.6.19-1.2898.2.3.fc7.

It is working. :)

So... I'm not sure _where_ the bug is, but now we know _what_ happens. The
problem is: dm related lines are missing from initrd after running mkinitrd with
kernel-xen-2.6.19-1.2898.2.3.fc7 and kernel-2.6.20-1.2932.fc7 up to
kernel-2.6.20-1.2942.fc7.
