Upgrading Airwave from 7.6.5 to 7.7.6 and applying kernel updates give me kernel panic on boot

I was upgrading my server to 7.7.6 but needing to get the latest OS CentOS 6.2 first.

My AMP was at 7.6.5 on CentOS 5.5, took the backup, ISO installed, restored....

 

7.6.5 on CentOS 6.2 on a Dell Poweredge R510 (pretty old).

I upgrade to 7.7.6 by download the upgrade package and doing it locally.

 

It upgrades fine, I reboot the machine it comes back online just fine.

 

If I apply the kernel updates it recommends I run into this error on boot.

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

https://bugzilla.redhat.com/show_bug.cgi?id=632412

 

Kernel updates it recommended

cd /root/svn/mercury/src/x86_64/rpms/CentOS-6; rpm -Uvh kernel-2.6.32-358.18.1.el6.x86_64.rpm kernel-headers-2.6.32-358.18.1.el6.x86_64.rpm kernel-firmware-2.6.32-358.18.1.el6.noarch.rpm

As soon as I apply those updates and reboot, I get the error message above and can no longer boot the server properly.

 

I have had to re-install Airwave back to 7.6.5 and leave it as is.

The boot partition prior to installing the kernel updates was 29% use. Lots of free space.

 

Seems like a linux issue more than an Airwave issue.

Gonna have to open a TAC case.

Instead of using the upgrade, can you try the 7.7.7 ISO image instead and once installed fresh, restore your backup of Airwave?  That should do it.

My backup is of a 7.6.5 though, I can restore to a 7.7.7? Didn't even know it was out.

I assume the database schema is similar.

Yes...that should work.  Just download the ISO...(MAKE SURE YOU COPY YOUR LICENSE TEXT)...deploy it as a new VM. Then, import the nightly backup from 7.6.x
