Re: [CentOS] Removing old kernels

I have the following kernels on my /boot:

2.6.18-128.1.6 2.6.18-92.1.18 2.6.18-92.1.22

I'm low on /boot space and need to remove the oldest version. It appears that I cannot use yum to remove since all of the versions are the same (only the release is different). I believe that I can use rpm to remove the old version, but I also need to remove them from the grub.conf. Any other considerations and/or methods?

You can also have the installonlyn limit bumped up if you want to automatically only keep n number of kernels.

# vim /etc/yum.conf installonly_limit = n

Set n to the number you want to keep.
