[Spacewalk-list] Rollback to the old kernal

[Alexandru Raceanu]

What I mean is that centos/RHEL by default are keeping the last 3 installed kernels (spacewalk has nothing to do with it) 

You will still need to remove the latest kernel packages from the machines, enrolling the machines to another channel with an older kernel is not sufficient.

Alex, 



You mean I should keep the old kernel on the clients it self. 

In regards to spacewalk, yesterday we tried to create another repository with old kernel and try to sync it with our servers., we tried to roll back, but it failed.

You should still have the old kernel installed on the machine(s) and you will be able to roll back the kernel by removing the kernel*-<version> packages using yum. 


I think by default centos keeps the last 3 kernel versions. 





In regards to spacewalk you can exclude all kernels and include only one version to be synced from external repo.

Does spacewalk will be able to roll back to the old kernel? 



For example I ugraded the CentOS from 6.8(kernel 3.0.0 for example) to 6.9 (kernel 3.1.0) Can I roll back to 6.8(kernel 3.0.0)? 





Thanks
