CLVM clarification - general.
I've been reading up on Linux clustering and successfully set up a load-balancing cluster in a lab environment. I'm going to tear down that setup now and I want to learn about storage clusters.
After reviewing some of the clustering documentation on the Red Hat site, I have some confusion about storage clusters and thought I might be able to get some general questions answered here.
In the Red Hat diagrams, they model a storage cluster in a manner that looks similar to several servers accessing a SAN. In my lab, I want to take a different approach.
For my purposes, I have 3 Linux servers, each system has two 40GB hard drives. My goal is to load the Linux OS on the first drive of each of the servers, and to allocate the second drive in each server to be used as storage in the Linux storage cluster.
So here are a few questions I have...
1. First... is this approach possible?
2. If so, when I create the filesystem on the secondary drive of each server, do I use GFS?
3. Are you LVM2 and CLVM mutually exclusive? If so, do I have to use CLVM to do what I'm trying to do?
Thanks in advance.
