CentOS

I am trying to build an ovirt cluster based off of some older gaming PCs that I am running into trouble on. I have no problems setting these hosts up as virtualization hosts in a stand alone fashion, however I am found a compatibility issue with the CPUs which are AMD Sempron II x4 models (I don't r...

Sadly, in my environment Puppet isn't necessarily an option. We are using a CM product just not puppet, that passes through local commands / scripts from the CM server to the clients.

I am learning sed in a very hit or miss manner, sorry... I am not looking for a spoon fed just do this to fix your problem, I am looking to understand how to use sed to solve my problem so that the next time I come accross this I can solve my own issue.

Was getting corrupted video, looked almost like bad video RAM, but this is across multiple systems and cards. Same make and model in a cluster. Also getti...

Well, yep. That kind of explains it doesn't it?

Okay so here's the scoop. I have 2 identically configured systems. I was planning on a cluster but hadn't got there yet. The host I had hooked up started acting funny, let's lay out the hardware first... Mind you, these 2 hosts are 100% hardware identical. So if I had a hardware failure on one, the ...

Been there, done that, bought the T shirt. The big issue is, these are UEFI hosts, and documentation on reinstalling grub on UEFI is a bit sketchy... Been looking, but no joy.

So last thursday, we were doing normal maintenance activities, patching etc... when 2 nodes of a cluster were patched and sent down for reboot. Neither host came back online. I can access them via iLO and I keep getting sent over to a no OS found prompt and it tries to boot from PXE. I booted to the...
