HI,

My server running Solusvm its the host with 4 vps servers created on it as a boot partition of 250MB but after the last update with new kernel i now only have 60MB left
and just wanted to know if there was a command i could use that would clean the boot partition up and remove some old kernels not in use, to free up some space.

This is what i get when i run command rpm -q kernel

kernel-2.6.32-358.el6.x86_64
kernel-2.6.32-431.el6.x86_64

This is the list of files in the boot partition

Two things you can do without any issues:

- uninstall old regular kernels, you aren't using them anyway
- remove old kdump files from the kernels that you don't use or don't exist on your system anymore.

You could alse remove old vzkernels, but I prefer to keep at least one vzkernel that is verified to work well for my systems (besides the active one, and that is not always the latest one).

After you remove either a kernel or a vzkernel, make sure grub has the correct kernel set as default (same as you do after a regular upgrade happens).

Anyway, even if you end up with 3 regular and 3 vzkernels, your /boot partition should be just about big enough.

Hi thanks for the reply, but this is all new to me and not sure how to remove them, also when i do yum update i have never checked grub to see which kernel is being used.
