Cleaning up old kernels (with kernel-ml)?

[Przemas]

I've just got a message on low disk space on /boot - how do I clean old kernels and all the mess from there taking into account I have kernel-ml as well?

Choose kernel version to remove.

# yum remove kernel....

[TrevorH]

package-cleanup --oldkernels --count 2

May need yum.conf amending with kernelpkgnames=kernel-ml but never tried with kernel-ml so it may work without or it may not work at all.

Yum has option 'installonly_limit'. The options default is 3, but CentOS seems to set the value to 5.

5 regular kernels and 5 kernel-ml definitely take some space.
As preventive maintenance, make it less.

Hello

Code: Select all

package-cleanup --oldkernels --count 2

works but will leave 4 kernels two 3.10 and two 4.12 (currently)
