what version am i running and how do i upgrade

[forums]

just curious seems like I am running an older version (just fyi also have ksplice) but when i run yum update, it says nothing needs updating here is my output

[name@server] ~ >> uname -r
2.6.18-338.9.1.el5.lve0.8.32
[name@server] ~ >> uptrack-uname -r
2.6.18-374.3.1.el5.lve0.8.44

yum upd ate

How do i make sure i am updated to the latest version?

Thanks

You are running lve0.8.36 feature wise, and lve 0.8.44 security wise.
To update to latest kernel version, check your /etc/yum.conf
Remove kernel* from exclude line
Run:
yum update kernel

reboot.
It is also possible that you already have latest kernel installed, and just need to reboot. To do that -- run rpm -qa|grep kernel
See if lve0.8.44 kernel is installed (you can also check /boot/grub/grub.conf)

Igor,

ok yes looks like a reboot solved this. So first, is ksplice actually worth running then if it doesn really update things properly?

second, when i view my OS in WHM it says i am running CLOUDLINUX 5.7

how do i update to the new 6.X version?

Thanks
John

I think ksplice worth it, though it depends...
If you need latest features, like ability to change number of cores on the fly, or cagefs3 -- you would have to reboot.
Yet, I still have lots of customers running lve0.7.49 kernel from more then a year go, perfectly safe from security perspective due to ksplice, and they didn rebooted once since then. I think I have seen someone on even older kernels.
So, if you don really need latest features, and uptime is critical -- ksplice is a must.
If you think that rebooting once or twice a month is ok -- you should be fine without ksplice.

Regarding upgrade to CL 6 -- it is not possible https://helpdesk.cloudlinux.com/inde...-cloudlinux-6x
BUT: We will soon add ability to run CL6 kernel on CL5, which should be close to same thing for many hosts.

[john]

oh i see the versions are based on the centos rhel version numbers so basically it involves upgrading the whole server software. boy that sounds like trouble in the making!

is there any real reason to try and upgrade to rhel 6?

also do you keep updating the 5.X stream as well?

thanks
John

[iseletsk]

No, you can upgrade the same way to CL6 -- I am was just showing the approach. It is exactly the same.
And yes, we will continue updating 5.x

Igor,

ok another issue on upgrading, Ive run yum update kernel

rebooted twice and still see this that I am using 8.5.4?? any ideas? see below

uname -r
2.6.18-374.12.1.el5.lve0.8.54
[@] ~ >> uptrack-uname -r
2.6.18-408.el5.lve0.8.58
[@] ~ >> rpm -qa|grep kernel
kernel-devel-2.6.18-374.12.1.el5.lve0.8.54
kernel-headers-2.6.18-408.el5.lve0.8.58
kernel-2.6.18-374.12.1.el5.lve0.8.54
kernel-devel-2.6.18-374.18.1.el5.lve0.8.57
kernel-2.6.18-374.3.1.el5.lve0.8.44
kernel-devel-2.6.18-408.el5.lve0.8.58
kernel-2.6.18-408.el5.lve0.8.58

the grub file shows 8.54 and 8.44 lines in it, nothing about 8.58?

Thanks
John

try doing yum update kernel

[john]

I did that as i mentioned, it went through and said it upgraded it but after reboot, these are the results i get.

other thoughts?

[iseletsk]

Try re-installing the package. If it doesn work -- I guess the thing to do is to edit grub.conf by hand. Sometimes is the only way to do it.

[john]

Igor,

would you mind telling me how to reinstall a package OR how to edit grub correctly??

Thanks
John

[iseletsk]

Re-installing package:
rpm -e kernel-2.6.18-408.el5.lve0.8.58 --nodeps
yum update kernel

Editing kernel -- it would better if you contact our support and we would do it for you. It just to easy to make mistake.
Yet, overall, make a copy of the topmost kernel entry in /boot/grub/grub.conf
Change filename for kernel & initrd to the versions that have lve0.8.58 in it (find actual file names, as it will be different)

[john]

igor thanks,

removing then reinstalling did the trick

Thanks
John
