In my Centos 7 the /boot is getting full

danielsender1 · 07-15-2020, 06:45 PM

I ran package-cleanup --oldkernels --count=2, but the img and vmlinuz files don't disappear, is there anything else that will free space?

Thanks

You could use the rm command, or better yum remove.

danielsender1 · 07-15-2020, 07:26 PM

The rm command is a bit risky, is there any automated procedure.

Yes, yum remove.

Of course, it still requires you to remove the correct kernel version(s). Generate a list of installed kernel versions with a command like yum list installed kernel* or rpm -qa | grep kernel-, then yum remove the older ones.

Yum remove, any particular indicator after the "remove"?

If the kernels are not known to the package manager you have no other choice.
On Fedora I list the current ones know to dnf (does CentOS still use yum ?) and manually "dnf remove ..." the old ones I have laying around from manual installs.

Hmmm - you folks type too fast ...

I updated my post.

Centos/RHEL 7 does.
Centos/RHEL 8 uses dnf, but symbolically links it to yum, so that old people like me have an easier learning curve.

Sorry, can you be more specific in the command to use?

michaelk · 07-15-2020, 07:56 PM

How big is your /boot partition?

Post the output of the command
rpm -q kernel

Example to remove a specific kernel
yum remove kernel-3.10.0-327.36.3.el7.x86_64

danielsender1 · 07-15-2020, 07:57 PM

[root@vivaldi boot]# rpm -q kernel
kernel-3.10.0-1127.10.1.el7.x86_64
kernel-3.10.0-1127.13.1.el7.x86_64

Size is 500 MB

Your boot partition is 209 GB?

Typically a separate boot partition is created of about 1 GB. At the moment with 5 kernels my boot partition is only 391 MB i.e. 39% used. Post the output of the command

df -h

michaelk · 07-15-2020, 08:17 PM

Ok correction 500 MB... I assume that you did not use the automatic partitioning when you installed version 7...

And which vmlinuz files are still in your /boot?

I would not attempt to manage a Centos system before learning the foundation of software management with yum.

I said:

yum list installed kernel* or rpm -qa | grep kernel-, then yum remove the older ones.

Since I don't know the kernel versions that are installed on your server, I can't be more specific.
