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

Hello,

I installed CentOS 4.2 (RHEL4 based) on a server (P4 3.4, 4GB mem,
2 x 250GB SATA-drives). I''ve tried both official Xensource RPMs and
the CentOS RPMs posted by Aaron Weller, but I can''t get neither to
work. I''m running LVM on top of software RAID1 (autostarted) and
it works fine on regular CentOS kernel, but the Xen dom0 kernel
doesn''t boot. I get:

Loading dm-mod.ko module
device-mapper: 4.4.0-ioctl (2005-01-12) initialized
Loading md.ko module
md: md driver 0.98.1 MAX_MD_DEVS=256, MD_SB_DISKS=27
Loading raid1.ko module

Loading dm-mirror.ko module
Loading dm-zero.ko module
Loading dm-snapshot.ko module

Switching to new root
switchroot: mount failed: 22
umount /initrd/dev failed: 2
Kernel panic - not syncing: Attempted to kill init!

And here it ends. The disks are detected fine under Xen as well,
so the problem seems to be RAID autorun. I found a post on some
mailinglist that advised to compile the RAID modules into the
kernel. I tried that but with the same results. I haven''t tried
Xen 2.0 yet on this box, but I have another box with similar setup
(LVM on RAID1) with Xen 2.0 which works fine.

Any clues?

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

Hello,

Yes, the disks are detected fine on the same devices (/dev/sda and
/dev/sdb) on both kernels (regular and Xen dom0 flavor).

please provide full dmesg (regular and dom0) and your hardware specs
(motherboard/chipset and raid cards will do)

Hardware configuration:

- 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:

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.

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?

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.

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

I too am having a similar issue. It actually occurred with and with out LVM,
the common denominator was Software RAID 1. I used both the RPM install and
the scripted RPM install. I also rebuild the initrd just to make sure it
wasn''t missing something, but as you can see in the dmesg it looks like
it''s
picking up the modules/drivers for everything. Running CentOS 4.2 and
everything boots find with the standard kernel. Hardware is a Pentium 4 D
3.0MHz, Intel 945G chipset, dual SATA Hatachi Drives, and 4GB ram,  if any
of that matters.

Any help would be greatly appreciated, I''d consider going over to
Fedora if
I thought it would matter but I''m thinking it probably wont.

Here''s the output of my DMESG:

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

Have you tried booting off the demo CD and then having a poke around? 

I seem to recall that at least at one point, native linux required the
MD and raid stuff to be built into the kernel (rather than a module) for
RAID autodetect to work. Does anyone know if this is still the case?

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

Please correct me if I''m wrong, but I recall, raid should work as a
module
if you have it in an initrd.  Raid must be loaded in the kernel before the
raid devices can be mounted.

With raid1 (and only raid1) it may be possible to mount one of the drives as
if it is not raid for readonly, and load the module that way, then unmount
it and mount the raid filesystems.

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

Well, from CentOS it looks like it''s a module / initrd so
that''s out.
Downloading both demo and test cds now to see what they say.

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

Okay, booting up to the Demo CD. Boots fine, however during init I get
the same error:

raidautorun: RAID_AUTORUN failed: 19

I even tried setting the raid config in the kernel parameters in grub at
boot:

md=0,/dev/sda2,/dev/sdb2

cat /proc/mdstat shows nothing, any clues?

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

It''s a good possibility, maybe for disaster recovery or something of
that nature it would be good, but for production that wouldn''t be
suitable, especially since it works properly with the original
distributions kernel. Something is amiss here with the kernel I think.

Do all the modules appear to be loaded OK (cat /proc/modules)?

Can you mount the raidset manually?

I''d be rather surprised if raid itself wasn''t working, but
then its hard
to understand why the autodetect stuff wouldn''t work.

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

Yes, the md driver is there, and I can modprobe raid1. however I can''t
see /dev/md0 with anything. I installed the mdadm tools and they are of
no help as well.

fdisk sees the raid partitions though.

guys,

are you able to mount single partition from the raid array on the demo cd ?
like mounting just sda1 *or* sdb1 ?

and if yes, are you able to read what''s on the partition correctly ?

Cheers,

I tried the demo CD. It doesn''t autodetect/autorun anything, but I was
able to get both RAID1 and LVM running by installing the necessary
packages with apt-get. So they do work.

Maybe this has specifically something to do with the raid autorun
functionality, since it breaks when upgrading to the Xen dom0 kernel?

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

Hello,

Got Xen 3 to work. I was booting the wrong kernel which didn''t have
the raid modules compiled in, so when I switched to the compiled-in
version, Xen booted up just fine. So there''s something wrong with
either the modules themselves or the initrd.
