[Clusterusers] Rebuilding the cluster

[Wm. Josiah Erikson]

     OK, this sounds like a great time to start. We'll probably start 
next week, and I'd expect the cluster to not be fully functional again 
until the week after all the power outages, so it'll end up being out of 
commission, for the most part, for about two weeks. We're currently 
doing power-rebalancing prep work, but feel free to spool jobs over the 
weekend.

The actual downtime of the cluster would probably be a day or two, plus lots of growing pains as I re-install and reconfigure everything, as there isn't really much of an upgrade process - it's almost like starting from scratch every time. So, I'd say figure a week until we're back up and fully functional.
