High availability Linux clusters: recommended reading?
I'm in the pre-planning stages for a high availability Linux cluster that will likely have just two nodes to begin with. (It will run on RHEL, if that matters.)
This is entirely new terrain to me, and while I'm able to google for information and read book reviews on amazon, I thought I'd solicit ideas from folks who are intimately familiar with high availability (not to be confused with high performance) clusters.
I read through the first couple chapters of 'Linux Enterprise Cluster: Build a Highly Available Cluster with Commodity Hardware and Free Software' by Karl Kopper over the weekend. It seemed like a ok starting point for a clustering novice.
Any informed opinions on that particular book? Any other recommendations?
[ Note: I'm new to clustering, not to Linux. ]
