Should I upgrade my kernel?

[Lucas]

I currently have a CentOS Enterprise 4.6 server running with kernel 2.6.9-67.0.4.ELsmp. I was wondering if I should upgrade to kernel 2.6.24.3, plus I am looking forward on doing my first kernel upgrade to learn the process.

There is a LOT to learn about compiling kernels.

Read ALL of the changelogs between your current version and the new version. There are some major changes somewhere around .12 - .24 especially with sata and firewall stuff.

You could EASILY make your system non-bootable or unstable.

If you don't have physical access to the machine, make sure you have someway of manually going back to a previous kernel in grub.

Anywhere I could learn about this?

Google is your friend!

Here is an article on Google dealing specifically with updating a kernal on CentOS-4

http://kernel.org has all the actual kernels and changelogs.

Do you think I would need a patch on the kernel for my current system? I have a system from SoftLayer with CentOS 4.

I also don't have the following line on my modprobe.conf

# alias scsi_hostadapter1 mptscsi

Only this:

alias scsi_hostadapter usb-storage
alias eth0 e1000
alias eth1 e1000
alias scsi_hostadapter1 ata_piix
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
