Cluster Chapter in OpenSolaris Bible
By Nicholas Solter on Mar 06, 2009
In addition to my day job as an engineer on the Sun Cluster team, I spent most of my nights and weekends last year writing a tutorial and reference book on OpenSolaris. OpenSolaris Bible, as it's titled, was released by Wiley last month and is available from amazon.com and all other major booksellers. At almost 1000 pages, my co-authors Dave, Jerry, and I were able to be fairly comprehensive, covering topics from the bash shell to the xVM Hypervisor, and most everything in between. You can examine the table of contents and index on the book website.
Of particular interest to readers of this blog will be Chapter 16, “Clustering OpenSolaris for High Availability.” (After working on Sun Cluster for more than 8 years, I couldn't write a book like this without a Chapter on HA clusters!) Coming at the end of Part IV, “OpenSolaris Reliability, Availability, and Serviceability”, this chapter is a 70 page tutorial in using Sun Cluster / Open HA Cluster. After the requisite introduction to HA Clustering, the chapter jumps in with instructions for configuring a cluster. Next, it goes through two detailed examples. The first shows how to make Apache highly available in failover mode using a ZFS failover file system. The second demonstrates how to configure Apache in scalable mode using the global file system. Following the two examples, the chapter covers the details of resources, resource types, and resource groups, shows how to use zones as logical nodes, and goes into more detail on network load balancing. After a section on writing your own agents using the SMF Proxy or the GDS, the chapter concludes with an introduction to Geographic Edition.
This chapter should be useful both as a tutorial for novices as well as a reference for more advanced users. I enjoyed writing it (and even learned a thing or two in the process), and hope you find it helpful. Please don't hesitate to give me your feedback!
