Geoffrin is now serving as the main database server (with memory down to 2 gigs I wasn't able to detect any errors in memtester). Ursula is now a replicated slave; if Geoffrin explodes in theory we should be able to switch back over to Ursula.
I also put the initial database onto gunther, but haven't finished setting up mysql there. Will make that a replicant too I suspect. Only 1GB of memory, but it's got the big fast raid configuration that is probably a better tradeoff if we have to use it.
At some point in the next day or so I'd like to get one or another of the faster machines to take over en.wikipedia.org and get rid of en2.
Also, if things don't fall down we can start taking down the extreme anti-slowness measures again.
