Using the packages bundled with CentOS 5 (started at 5.0 and at 5.3 now). Although the packages are version 2, I couldn't get the fancier version 2 xml style configuration to work, it just kept crashing one of the daemons. So I stick to the older "haresources" style and it works, but I'm always suspicious about how well it'll behave in real tight corners. I have a suspicion that I can learn a lot more and gain more in regards to redundancy and fail-over but try as I might, after a few weeks of fiddling with the more fancy configuration format even just to serve a simple VIP I had to go back to haresources. This was over a year ago so maybe it improved since? What about RedHat Cluster Suite? It's part of CentOS as well, as far as I'm aware, it's based on Linux-HA, and a worker of mine has good experience with it so I'm thinking of maybe checking it when we have some time to breath again. Does it do anything better? --Amos _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
