I restarted my Cent0s server on a virtual box vm. When I restarted the vm, the cent0s would do the intial boot up but will not go through all the way. It is abel to find the volume group "VolGroup00", but it is not able to find the device with a specific uuid. It also said that it could not find the filesystem. /dev/root/.

Anyone have any suggestions??? Thank you

exactly where is /dev/root pointing. It should be a symlimk.

Have you recompiled the kernel?

I have the same issue (3 years on from the original post). I'm hoping that replying will activate a reply from someone that has a solutions.

Thank you

Every time in my experience, this is an admin error. Are you sure the uuid is totallycopying it correctly?

Sorry I don't understand. What do you mean an admin error. I get the same error, the uuid is obviously different but the error is the same. I thought maybe a disk not spinning up or timing out?

Sorry.I meant a copying error in copying the uuid.
