Question Linux Clustering (and Installation on Servers)


I have a cluster of seven servers that are running the Fedora Core 6 OS and some propriety software which uses MPI.

I have two questions:

1) Is Fedora Core a "good" choice for clustering servers? If not, what other distribution should I try?

2) I need to create more clusters. I have several racks, each with N number of servers. How do I efficiently install an OS and my software onto each server? (I did each box of the first cluster, by hand -- very tedious!)

Well.. If you're going to go with Fedora I would go with the current stable release which is Fedora 13. One big issue I see with using Fedora in production is that its updated approx. every 6 months. So you have to keep on your toes with updates. Also it depends on what type of hardware you are running all this on. If you want a a free stable enterprise level linux OS I would look at CentOS, its a free clone of Red Hat.

If they are all roughly the same install you can use kickstart to automate as much of your install as you want.

I've tried using kickstart, but haven't found the documentation very helpful. Any suggestions?

Also, if anyone else is using linux for clustering, I am curious to hear what linux OS you are using.

To be honest. Most of the kickstart documentation I've read was hard to follow until I got the hang of it. The hardest part to me was getting the partition layout how I wanted it. One way to get the hang of a kickstart install is to do one install manually. Once you are done with the install you can look at /root/anaconda-ks.cfg, the install will build you a kickstart file. You can then modify that to use as your kickstart file for future installs. If you have any specific questions post here and someone will help you. It can be a very frustrating thing to learn. But once you get the hang of it, its pretty powerful. Someone else may suggest other hands free install methods that may be better.

If you havent read through the Red Hat docs, its a good place to start. Take the kickstart file that was auto generated and read the docs about what each section does. Then you can figure out how to modify it to suite your needs.
