Title: 7.2 --> 7.3 centos kernel is this ok?
Post by: okepc on January 21, 2008, 11:44:42 AM

yesterday i yummed my sme from 7.2 to 7.3.
Finished and rebooted with signal-event opst-upgrade and reboot
I noticed at the boot screen on the top of my list it had installed a centos kernel.
kernel-smp.i686 2.6.9-67.0.1.EL
kernel.i686 2.6.9-67.0.1.EL
No changes made to yum all is stock config.

Is this ok or should i have a sme-server rebranded kernel in grub?

Regards

Dirk

For a multi processor machine it

Code: [Select]

uname -ashould output this:

If your output looks very different I would advice you reporting this as a bug in the bugtracker as IMHO this should not happen.

Edit: changed single to multiple to match output

I always thought the first kernel installed from cd was titled SME Server and any yum'd kernels were titled CentOS.

I'm not sure now....

I always thought the first kernel installed from cd was titled SME Server and any yum'd kernels were titled CentOS.

I assumed the same and it is this way on my test machine which is installed from a SME Server 7.3 CD and is up-to-date. Since the applied updates do not include a kernel update I guess a clean SME Server 7.3 should look like this:

Code: [Select]

# NOTICE:  You have a /boot partition.  This means that

Small mistake. SMP = more than 1 processor. (http://en.wikipedia.org/wiki/Symmetric_multiprocessing)

There it is.... Title CentOS

All other kernels are sme branded.

So the question is , is this the right kernel?

So the question is , is this the right kernel?

The developers don't compile or alter kernels. The are identical to upstream (CentOS).

The key thing is that your kernel modules match your kernel.

uname -r
rpm -qa | grep kmod

Should the kernel be labled as SME Server? The bug tracker seems to indicate they should. Perhaps this should be taken to the bug tracker to get a definitive answer.

Edit:

Good example

Code: [Select]

[root@tiger ~]# uname -r
2.6.9-67.0.1.ELsmp
[root@tiger ~]# rpm -qa | grep kmod
kmod-slip-1.0-2.2.6.9_67.0.1.EL
kmod-slip-smp-1.0-2.2.6.9_67.0.1.EL
kmod-ppp-1.0.2-2.2.6.9_67.0.1.EL
kmod-appletalk-smp-1.0-2.2.6.9_67.0.1.EL
kmod-appletalk-1.0-2.2.6.9_67.0.1.EL
kmod-ppp-smp-1.0.2-2.2.6.9_67.0.1.EL
[root@tiger ~]#

Bad Example

Code: [Select]

[root@c3 ~]# uname -r
2.6.9-67.0.1.EL
[root@c3 ~]# rpm -qa | grep kmod
kmod-bnx2-1.4.43c-2.2.6.9_42.0.3.EL
