Option to remove old kernels

mmmhhh… what about using google, find the answer (took me 5 secs) and do it yourself? :slight_smile:

The problem will only occur when you have a dedicated /boot. What is default with NS? is /Boot on a separate partition? If so, regular removal of the obsolete kernels is a good idea. You don’t want to be confronted with a full /boot.

IF there is already a rotation of 5 by default, this should not be a problem.

@zamboni please stop the rtfm mentions. They are counter productive and only set a bad atmosphere in the community.

all of us started from the RTFM and if now we know something is exactly for this reason…
so, for some trivial things (like this one), I think that my post is educative…

anyway, if you really think that feeding people with fishes instead of make them learn to fish is the right way, you’re welcome.

I must have a problem…
I made theses searchs:
SME Server kernel rotation
SME server kernel backup rotation
SME server old kernel backup rotation
SME server old kernel backup rotation upgrade
SME server kernel backup upgrade

I wasted lot of more than 5 sec… And don’t have the answer yet…

When you posted, I think " damned, he’s right…"
but I must admit… I must googling wrong, can you give me 5s more?..:wink:

“centos keep old kernels” works fine for me…

ah, just to be clear, I never searched for this info before (don’t needed, always relied on the OS default)

No, I think you should point people to the fishes and provide them the net to catch them instead of yelling from a distance to go get some fish themselves.

I did it

I told jim “google”, not “do it yourself”

We obviously have a different way of helping others. I prefer the polite way.

well… english is not my language, but I help everyday people in english… I helped Jim and I’m quite sure I was not unpolite…

moreover, Jim seems grown enough to defend himself.

anyway, as usual, you’re free to think what you want and welcome when you express your thoughts

I had totally missed this answer, where there’s the right information.

Now I have a doubt… the information is in the dnf.conf or somewhere (cause of SME/NS)?
I’m at work and can’t verify by myself, now

The option is inside /etc/yum.conf and it’s called installonly_limit.

Did I need to reboot?
Because now I have a bunch of 6 kernel :fearful:

Finally to clean to system… I had to install yun-utils

# yum install yum-utils

and clean up

# package-cleanup --oldkernels --count=2

@Jim you can also make a custom template for yum.conf file :slight_smile: in order not to delete old kernels by your own.

I’m curious to know why this parameter don’t work…

This e-smith layer… Let’s talk about it :camel:

It works!

it Indeed keeps 5 kernels

But I put it at 2…
And NS keep 6 Kernels



cat /etc/yum.conf

[root@host1 etc]# ll /boot | grep -c vmli
