I've spent the last month or so building linux clusters. 2 of them in a VM environment on fedora 15. I went through the Clusters from Scratch Tutorial; which sort of worked. At this time I am looking for a sanity check.
My requirements are to have a 4 node load balanced cluster with shard access to a SAN volume. The SAN will be using GFS2. I believe I need corosync, Openais, PaceMaker, and GFS2 utilities. Where the confusion is coming from is the use of CMAN in the clusters from scratch. It seems from what I am reading that Pacemaker should be able to do everything I need and I am wondering if the use of cman is old information. Any thoughts comments or suggestiosn are greatly appreciated, Thanks in advance.
