Dear Hal, this limitation means, that you can only run up to 16 rgmanagers in one cluster infrastructure. rgmanager thereby is only needed if you build HA services like a active/passive MySQL cluster services. If you like to build a 100 node webserver farm with external loadbalancing/failover - such as LVS and/or keepalived - no rgmanager is needed to be run on that cluster. In this case you can set up a 100 node cluster with shared gfs devices as you like. I too recommend you to have a look at http://open-sharedroot.org/documentation. The concept demonstarted on that page is do build a n node cluster from one filesystem single image which keeps administration simple. Greetings, Christian Best Regards, Christian Schäfer Abt.
