hmm, I was having a heck of a time with clustering the community version (2.9B in a testing environment). Followed the instruction to the T, just doesn't work. The repository synchronization is very very inconsistent. Sometimes, if you have a good karma, it would work for a while, and then stop. Sometimes, you have one node (node A) synchronize withe node B, but not the other way around. You restart both nodes, then node B would synchronize, but not node A. You restart them again, and they won't sync anymore. What the heck.
That's in a small network by itself, for testing purpose only. The network has no problem at all, and there's nothing running on it.
This drives nut for a whole week before I totally gave up.
