I have a CentOS box at home and I’m trying to install the latest Kernel but it is failing as my /boot
partition is too small and there’s not enough space.
Can I just use rm
and delete some of the old Kernels stored in there? Or do I have to resize the partition so that I could have more space? Or is there a better way to sort that out?
Thank you!

Hello,
I’ve noticed that with CentOS by default the /boot
partition is quite small, in some cases it could be only a few megabytes. If this is the case with when you try to update your kernel, you could get an error complaining about not enough free space on /boot
.
I would strongly recommend not using the rm
command! Here’s an easy and safe way on how to free up some space so that you could complete your kernel update as normal.
yum-utils
yum install yum-utils
--count
argument to at least 2:package-cleanup --oldkernels --count=2
This is pretty much it, you can then go ahead and update your kernel as normal:
yum -y update kernel kernel-headers
Please note that you would need to reboot your server in order for the change to take effect.
To check your system information you could then simply run:
uname -a
Hope that this helps! Regards, Bobby Source
