CentOS / Redhat boot partition full – remove old kernels

Sometimes /boot partition gets 100% full on a CentOS/Redhat/Fedora system. To resolve this you can use a yum-utils package to clean up older kernels and configure yum not to keep too many versions.

First, make sure yum-utils is installed on your system:

yum install yum-utils

Next, check the list of kernels that you have installed:

rpm -q kernel
kernel-2.6.32-604.30.3.lve1.3.63.el6.x86_64
kernel-2.6.32-673.26.1.lve1.4.20.el6.x86_64
kernel-2.6.32-673.26.1.lve1.4.22.el6.x86_64
kernel-2.6.32-673.26.1.lve1.4.24.el6.x86_64
kernel-2.6.32-673.26.1.lve1.4.27.el6.x86_64

Now to keep only two of the latest kernels, run:

package-cleanup --oldkernels --count=2

To make the change permanent when installing / updating kernels via yum, edit the /etc/yum.conf file and update the following parameter:

installonly_limit=2
