Update of application screws with the disk ....

Hi,

Running SLES11sp2 and running Datasync as a XEN virtual machine.

I upgraded the Novell Datasync application on the VM and this went thru fine
and the system update and is working correctly.
but …
on a reboot of the virtual machine generates the following error:

waiting for device /dev/xvda to appear: ok
invalid root filesystem
exiting to /bin/sh
$

I then type “exit” and then everything works 100%

The “mount” command returns “/dev/xvda1 /boot” and “/dev/xvda3 /” which all
looks correct.

Any ideas …

Regards
John

Hi John,

I’ve sometimes seen that the VM’s kernel somehow didn’t catch the root file system name correctly. You might want to try to set "root=/dev/xvda3"as an EXTRA parameter in your DomU’s configuration file and see if that helps.

Regards,
Jens

Hi John,

You may have encountered Bug 755924. Under certain conditions during an
upgrade or when applying patches, initrd may be built incorrectly.

The solution is quite simple: run mkinitrd to correctly rebuild initrd.

Let me know if this resolves your issue.

Gives you the warm fuzzies doesn’t it?
I’ve hit that bug as well. Good to know it’s
not fixed in SP2, I can hold off on that a bit longer.

Hey Kevin,

Running “mkinitrd” fiddled in the OS and fixed the issue.

Many thanks

John

Hey Jens,

As per Kevin Boyle I ran “mkinitrd” which fiddled in the OS and fixed the
issue.

Hey GofBorg,

As per Kevin Boyle, just run “mkinitrd” this fiddles in the OS and fixes the
issue.

From time to time I see posts in various forums from others who have
encountered this issue.

I had a bug opened for this almost a year ago. While patches have
reduced the chances of this happening they have not yet completely
resolved the issue. I have asked that it be documented in a TID.

For anyone else who encounters this issue, please refer to this TID:
TID 7011861 Invalid root file system after upgrading or applying
patches.
