Re: [Xen-users] Xen 3.0.0 + RAID + LVM + CentOS = problem

Hi,

Yes, this is built from a source RPM (config was modified to
put all CONFIG_MD_* stuff as compiled in, not module). Both
pre-built (official Xensource packages and unofficial CentOS)
packages produce the same symptoms.

I'll try the demo CD.

This looks like a DIY build. Did you change the config at all?
Have you tried booting the demo CD and having a poke around?

Ian

Kernel panic - not syncing: Attempted to kill init!
  (XEN) Domain 0 shutdown: rebooting machine.

Hardware configuration:

- Intel Pentium 4 3.4 GHz
- Intel D945P motherboard
- 4GB DDR2 memory
- 2 250GB Seagate SATA drives
- Radeon X300SE

Software setup:

- CentOS 4.2 w/ all updates
- Software RAID1
- LVM2 on /dev/md* devices
- Boots directly from "Linux raid autodetect" partition
- Separate small partition for /boot

Partition table from /dev/sda:

Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot      Start         End      Blocks   Id  System
/dev/sda1 * 1 33 265041 fd Linux raid autodetect 
/dev/sda2              34         555     4192965   82  Linux swap
/dev/sda3 556 30401 239737995 fd Linux raid autodetect 

I guess the error code is ENODEV. I guess it looks a bit like
it's not seeing the disks properly even thought the boot messages
claims so.

Is there a easy way to boot to the initrd shell and look things
from there? I tried root=/dev/ram0 init=/bin/nash but with no luck.
