Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(0,0)
Hi all,
I just inherited a CentOS server running 6.2. As far as I can tell the system has never been updated, so I ran a yum update. Now the system will not boot, it is giving this error: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(0,0) After a few googles I see one solution is to boot from and older kernel and then do a: yum reinstall kernel The question I have is can I actually upgrade from kernel: 2.6.32-220.el6.x86_64 to: 2.6.32-573.3.1.el6.x86_64 Without any problems? I really don't want to re-install and go through all the reconfiguration and installation of all of the applications. |
Why are you using such a old release?
Actual is Centos 6.7 or 7.1. |

I don't want to go to 7 just yet, waiting until I get more comfortable with systemd. |
You should reinstall Centos 6.7.

Found the problem. For some reason when updating the kernel it did not install:
initrd-2.6.32-573.3.1.el6.x86_64kdump.img Even after doing a: yum reinstall kernel it did not work, so I kind of cheated I copied the file from another server and everything works now. |
