One core server and core duo processor MD issue
« on: July 16, 2007, 08:52:27 pm »
Hi,

I'm going to try LinuxMCE with one core processor server and MD with core duo processor. I couldn't manage to setup core duo MD. It couldn't find SMP kernel.

So, did somebody success install MD with Core Duo processor under LnuxMCE server with one Core processor?

Thanks in advance.

Michael--

Did you install Kubuntu with the default kernel?  I was under the impression that the default kernel detects whether the PC has SMP capabilities.  This way, you don't need to specify a particular kernel depending on the number of processors/cores.

Not I'm just going to do that. I have Plutohome installation with similar case. When I install server I chose the kernel type manually (there is a choice between usual and SMP kernel). But when I installed MD with core duo the system didn't give me a chance to specify kernel for MD. It detected processor automatically and tried to boot SMP kernel but since the server had usual kernel the installation was crashed. So, I'm worry about similar problem with LinuxMCE. That's why I asked people about success installation of core duo MD with one core server.

If I understand correctly you installed only LinucMCE server without additional media directors, right? The problem is not to install LinuxMCE on core duo processor. The problem is to add core duo MD to the one core server. In my case (with Plutohome) the MD couldn't find appropriate kernel (SMP). So, since I got that problem with Plutohome I worry about the same situation with LinuxMCE.

I don't think you'll see this problem if you do a fresh, clean install of Kubuntu Feisty 7.04, then install LMCE on top of that.  The newer kernel Feisty uses doesn't require you to select between smp and standard.  So the same kernel will work correctly with your dual cores when the image gets built for your dual-core diskless MD.

i also made the computer with AMD X2 working as a MD.

If I recall correctly the Kubuntu install doesn't even offer you that choice, it just installs the default kernel which has SMP enabled.  So I reckon this won't be an issue.  Apart from that, the MDs don't have to use the same kernel as the Core per se, I have updated the kernel (just recompiled with a small patch really) on my core and the diskless MDs are still using the original kernel.

I suppose I could test with a single-CPU core installation and an SMP MD, but then I'd have to reconfigure most of my network and I'm not *that* bored.
