[Xen-devel] switchroot mount failed

All,
I am running xen3.0.2  and xen unstable on RHEL 4, and get this error when
trying to boot Xen kernel(domain0)
......

mount: error 6 mounting ext3
mount: error 2 mounting none
Switching to new root
switchroot: mount failed: 22
umount /initrd/dev failed: 2
Kernel panic - not syncing: Attempting to kill init!
Then system reboot.In grub.conf,I have changed the root=LABEL=/ to the
actual device
(root=/dev/sda3),and make the same change in /etc/fstab,but I got same
error.*****

These two errors are serious. Either there''s something wrong with the
ext3 module you''re using (compiled for a different kernel?), or, for
some obscure reason, LABEL=/ isn''t supported.

Try specifying root=/dev/sda3 instead.

Re: [Xen-devel] switchroot mount failed

I have mentioned in my message that I have tried /dev/sda3 options
Also, I have compiled ext3 module for same kernel, matter of fact Xen source
code get a pristine kernel from kernel.org to complete the build. So, where
i am wrong? Any ideas
are welcome.

Regards,
Vineet

[Xen-users] Re: [Xen-devel] switchroot mount failed

You mean to provide builtin option in mkinitrd....
Now, I am trying

mkinitrd --builtin .... initrd-xxxx  2.6.xxxx

I just did make world and make install ....is there is to specify  to
compile scsi and ext3 in kernel ?

Hi,

Can xen developers kindly post relevant solution to this problem. I have
seen many times on xen list-  not a simple answer. It has come to the point

Re: [Xen-devel] Re: switchroot mount failed

Does teh kernel boot output indicate that the SCSI module has loaded  
and actually detected any discs (sda in particular)? This doesn''t look
like a Xen-specific problem.

Re: [Xen-users] Re: [Xen-devel] Re: switchroot mount failed

Hi keir,

Normal kernel is booting and detecting SCSI disk fine. When i boot in Xen
mode, it gives this problem. If you put search "switchroot mount
failed" in
Xen user/dev list, u will see this has been a common issuse with no solution
posted. Yes, I also believe it is problem with xen kernel not detecting the
SCSI drivers or something.
which log file u want me to check.

Regards,
Vineet

Re: [Xen-users] Re: [Xen-devel] Re: switchroot mount failed

Adding to this, i am not redirecting my boot logs to another machine. but as
i observed through boot process, it is detecting all modules, even mkinitrd
doesn''t complain about missing modules.

I don''t see any duplicates from anyone else if I use those search 
terms. Perhaps you can provide links to some threads with people having 
the same issue as you?

When the boot fails, do you see any lines of output from the kernel 
stating that it has found a block device ''sda''? If the machine
reboots
too quickly for you to read then try adding ''noreboot'' to
Xen''s command
line.

Re: [Xen-users] Re: [Xen-devel] Re: switchroot mount failed

Here are links to see for switch root problem ( specifically first link is
exactly similar).

I have re-installed OS and xen in my system ( as i messed up  with grub when
palying around it and in hope that i will rectify that error). I am not
getting same error now but i am getting following error:

PCI: If a device doesn''t work, try "pci=routeirq". If it
helps, post a
report
PCI : Bridge: 0000:01:00:0
  IO window :c000-cfff
  MEM window : fce00000-fcefffff
  PREFETCH window: e0000000-e01fffff

  MEM window : fce00000-fcefffff
  PREFETCH window: e0000000-e01fffff

I have tried pci=routeirq and apci=off, it still give me error

Yes, I know about noreboot option and I knew module were loaded and
detected.
Thanks for helping me out. I have been trying to make xen work on dual core
Xeon 2.8GhZ for last two days....and i have to try all options...so i am now
not able to replicate same error. I am using Xen 3.0.2-2. Kindly guide me
with this current error.

Vineet

The line above is not an error. It''s just useful information if a PCI 
device happens not to work. You should ignore it.

Re: [Xen-users] Re: [Xen-devel] Re: switchroot mount failed

Adding to this, I have now build kernel with scsi Fusion MPT drivers builtin
( i am not sure if that has removed that error-- in fact I am not sure till
this whole thing is working).

System hangs at this point. Any clue ?

Can you reproduce this with the latest xen-unstable tree?

I''ve been using Xen on a CentOS 4 system for about a month, and
I''ve had
my share of problems: this was one of them.

In my case, I was setting up a second domU, and every time I would boot
it, it would freeze at the "Switching to new root" step.  It was quite
puzzling because the new domU was based on an existing one that was
working perfectly.

During my trouble shooting, I discovered that my base image didn''t have
a /dev directory.  So, I created a /dev directory  (empty of course,
since CentOS 4 uses udev), unmounted the logical volume that contained
the domU, started it, and behold, it finished booting.  It''s now
running
smoothly.

Sooo, you might want to check that /dev exists before you start the
domU.  Even though /dev is populated at boot time, it seems a /dev
directory must first exist.

Regards,

Ranbir

Re: [Xen-users] switchroot mount failed

I checked /dev/ is also there. Also, I have tested with xen-unstable, I do
get switchroot problem. For now, I have moved to another machine to work on.
