Topic: are we at 2.6.9-55.ELsmp or 2.6.9-42.0.10.ELsmp ?

[christian]

Just watching a few threads on kernel level over the past few days and I'm now confused as to which kernel we are at for SME7.

After running all updates through the usual server manager panel I'm at 2.6.9-42.0.10.ELsmp.

However, I see others quoting 2.6.9-55.ELsmp. For example in thread: http://forums.contribs.org/index.php?topic=37178.0 .

Which is correct?

I think that he installed the kernel from the testing repo because the latest stable kernel is 2.6.9-42.0.10.ELsmp (at least on my server).

[DavidClarke]

Only I didn't.

The exact sequence I used was - Install from 7.1iso, reboot, yum update

So the centos kernel turned up without being specially requested.

smp kernels 2.6.9-42.0.3.EL and 2.6.9-55.EL are installed from the base repository, together with 2.6.9-42.10.EL (non-smp) from smeupdates

I have a total of 5 kernels to choose from in the grub menu, of which the CentOS 2.6.9-55.EL is the default chosen for my PC

The 7.1iso comes with .03 kernel, when you update to 7.1.3 you will have the .10 kernel.

bpivk is right in saying -55 kernel is from the smetest repo which is not enabled by default.

Or -55 is from the centos repos as 7.1 did not include the fix to exclude the kernel and various other rpms.  So, it is possible that a new install of 7.1, then a yum update would take you to the most recent kernel from centos.  Easily tested by installing 7.1 and doing a yum update to see if the issue is duplicated.  If so, the only work around would be to install 7.1, then yum update smeserver-yum so the proper excludes are added, then yum update to update to 7.1.3.  When 7.2 is released via ISO, then this issue should clear itself up as the proper excludes will be added.

Hi !

With a 7.1 CD, you have to exclude BASE from update (only the 1st time)
The right Kernel will be installed.
So you'll have to launch the updates process 2 times...

Hope it helped

Strange. I recently did a fresh installation with the 7.1 ISO CD-ROM, then I upgraded (without first excluding the "base" repository though).

After the upgrade, when booting my server I have the following options (excerpt from the grub.conf file):

Code: [Select]

title CentOS (2.6.9-55.EL)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-55.EL ro root=/dev/main/root
        initrd /initrd-2.6.9-55.EL.img
title CentOS (2.6.9-55.ELsmp)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-55.ELsmp ro root=/dev/main/root
        initrd /initrd-2.6.9-55.ELsmp.img
title CentOS (2.6.9-42.0.10.EL)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-42.0.10.EL ro root=/dev/main/root
        initrd /initrd-2.6.9-42.0.10.EL.img
title SME Server (2.6.9-42.0.3.ELsmp)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-42.0.3.ELsmp ro root=/dev/main/root
        initrd /initrd-2.6.9-42.0.3.ELsmp.img
title SME Server-up (2.6.9-42.0.3.EL)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-42.0.3.EL ro root=/dev/main/root
        initrd /initrd-2.6.9-42.0.3.EL.img

As you can see, I have the CentOS 0.10 kernel but I don't have the SME Server 0.10 kernel. If I query the release version in the configuration db I get "7.1.3" as a result. If my server is a 7.1.3 shouldn't I then have the SME Server 0.10 kernel? And, should I ever boot my server with the CentOS kernel? I'm a little bit confused here.

I have the base, smeaddons, smeos, smeupdates and updates repositories enabled. All available updates have been installed to this date.

Hi,

Yes, that's why you need to exclude base from the 1st update!

You have the wrong Kernel now, I don't know how you can fix it...
I'll try to boot with the original Kernel (2.6.9-42.0.3) and yum update... And hope that yum will install an older Kernel that the one installed on your server... I'm not sure it will work.
Search on the bugtracker or on this forum, you could find similar subjects (as it's a known issue with 7.1 iso)

You can also wait until this new Kernel is released for SME (in SME 7.1.4 or SME 7.2?)
Your server should be working with some bugs (all rpms that need a kernel module will not work, i.e. VPN)

If you didn't make a lot of configuration to your server, you should probably reinstall SME 7.1 and update it correctly. This could be faster!

[Frank VB]

I just ran a "yum update" on my server (release 7.1.3 currently running on the 2.6.9-42.0.3 kernel).

One new update was installed: smeserver-yum 1.2.0-32.el4.sme.

Executed the signal-event post-upgrade and reboot command.

Ran "yum update" again. Result: message saying "no packages marked for update/obsoletion". So, for the moment I'm stuck with the old kernel. Luckily for me it's only a test server.
 
If I have some spare time, I'll check out the bugtracker for a solution ...

Why do I always find this info when its too late?

Isnt this what announce or a mailing list is supposed to do, warn people of recent bugs etc and how to circumvent them?

Hi,

I found this very interesting article in the Wiki : http://wiki.contribs.org/SME_Server:Documentation:FAQ#Which_repositories_should_be_enabled

As you can see, you don't need to disable any repositories during updates if you previously installed all needed updates

Warning:
If upgrading from a system prior to 7.1 update 1, ie a 7.1 CD install or earlier,
you need to ensure you have the latest versions of the following rpms prior to applying the rest of the updates. This speeds up install process and avoids updates from centos that may be ahead of the distribution.

yum update smeserver-support smeserver-yum yum yum-plugin-fastest-mirror python-sqlite
signal-event post-upgrade; signal-event reboot

hi,

to solve your problem,

just have a look on this topic:

http://forums.contribs.org/index.php?topic=37713.0

But I think after a french install of a 7.1 iso, you have to do:

yum update yum

reconf. and then:

yum upgrade

(to be verified!)

It would be great to have a new ISO that solve this big problem after install and based on 7.1.3!
