Replacement of CPU causing mount errors

Since a failed CPU was replaced in my server I've been getting the following error message (notification by e-mail each day).

Output from your job 869
repquota: Cannot stat() mounted device /dev/root: No such file or directory
repquota: Cannot stat() mounted device /dev/root: No such file or directory

Any idea what this means and why replacing a component would cause this message and why the replacement of a CPU would cause it ??

what's the output from the following command
Code:
cat /etc/mtab
Thank you for replying.

Here is the results from the mtab:

Thanks for the reply.

I will give that a try later when I am in a position to reboot.

Also, I had tried linking to "/dev/xvda" using the command:

ln -s /dev/xvda /dev/root

How would I reverse this change I made ?

Any idea why the replacement of a CPU would cause that ?

Thanks in advance

It won't let me save the changes after doing a pico -w on that file and removing that line - not sure why.

Any ideas ?

Hello,

I suggest reporting this issue to your data center or a qualified system administrator so they can take a closer look. Manipulating your partitions is not recommended if you have no experience with those configuration files. There's a similar thread at:

/dev/root missing

Thank you.

Thanks for the replies.

Can anyone work out how replacing a hardware component could have caused this though ?

This question is better asked to a qualified system administrator or your hosting provider/data center, as it's not a common occurrence I've seen happen before in relation to the cPanel software.

Thank you.
