#32 Problem with mounting root partition after upgrade


Hi all,

I have a problem with my two coLinux installations
after migrating to new versions. In the first case (MS
Windows XP Home Edition SP1, notebook) I upgraded from
coLinux version 0.6.3 to 0.6.4 a few days ago. In the
second case (MS Windows XP Professional SP2, server) I
upgraded another installation from coLinux version
0.6.4 to 0.6.4-2. In both cases a have a problem with
mounting root file system. Error message follows:

VFS: Mounted root (ext2 filesystem).

# This process will install (if necessary) the coLinux
modules for the
# coLinux kernel.

Determining /, Found.
Mounting /
mount: Mounting /dev/cobd0 on /mnt/linux failed: No
such device
Closing /
umount: forced umount of (null) failed!
Failed. (trying again)
umount: forced umount of (null) failed!

initrd: umount failed on rootfs
Try to run coLinux without initrd. Comment out initrd
from configuation.

Press <Enter> to continue.

I tried to comment out initrd section, but I got this
another error message:

EXT2-fs warning: checktime reached, running e2fsck is
VFS: Mounted root (ext2 filesystem).
VFS: Cannot open root device "cobd0" or unknown-
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root
fs on unknown-block(117,0)

I spend few days with searching for help or advice on
Google. Unfortunately I didn't find any useful info. I
hadn't any problem with coLinux installations many
months - it was pretty stable. The reason for upgrade
was periodical system maintenance. I wanted to upgrade
my installations and then keep it them for next few
months. These strange errors appear after upgrade. Now
I am not able to use none of my coLinux installations.

I tried to remove/reinstall or downgrade both
installations to previous versions, but without any
success. So, I didn't change anything in configuration
file for longtime. Does anyone have some idea or
advice for me? Please, help. Thanks.

    Initrd has a problem while options in bootparms has no
    a "=", for sample your "nosmp". Colinux kernel has no
    support for smp, you can remove these options.

    Please try simpler bootparms, for sample:

    Double check, that your root filesystem exist and is
    "c:\Program Files\coLinux\OS\Debian\debian_root_reiserfs"

    Closing this request. As the problem has been identified as the initrd and the use of bootparams which have no '='s. If the problem persists post more information to the mailing lists and we'll try to help.
