A real live cluster

At work, I've been playing with a tiny cluster: 3 Sun V20z servers, each with a 2.2GHz dual-core Opteron and 2GB of memory. It's nothing special at all, but it's been a good way of getting familiar wiht Rocks.

One thing that's bitten me a few times is the documentation. The 411 service is described only in the 4.x documents, but still appears to be a going concern in the 5.x series...indeed, that's how I got LDAP and autofs working. And to test the cluster, the HPC roll documentation says to use cluster-fork...yet running cluster-fork gives me the message "cluster-fork has been replaced with 'rocks run host'", which is documented in the base roll
