We're on line with these limits:
40/CPU
320/GPU
planned Monday limits:
320/CPU
2560/GPU
With the MySQL replica down, read-only queries that would normally go to the replica will hit the primary instead. We'll see what the impact of this is.

Wrapping up the weekly "extended outage." Jeff's actually out today, but will be back to turn the servers on tomorrow (i.e. Friday, when I'm usually out).
I finally got around to testing a drive on mork (the mysql server) that the RAID card deemed "failed" at some point, but maybe that was a transient problem as it seems fine now. Nevertheless I went through the rigamarole of pulling that drive, putting a new on in, testing it, making it a new hot spare, etc.
That's all good, but the week in general has been tainted by mork issues in general. It had one of its regular mystery crashes on Tuesday (followed by a long recovery). Then last night, and again this morning, the RAID mirror of two solid state drives (where we keep the innodb logs) started going flakey on us. The partition would just disappear, sending mysql into fits. We were able to quickly recover, but we're abandoning the solid state drives for now. Honestly, they weren't adding all that much to the i/o picture because we were cautious about how we were implementing them. Now I'm glad we were cautious. The upshot of all the above meant that we had to recovery the replica as many as four times so far from the weekly backup. What a pain. The latest replica recovery is happening as I type this. All I hope is that all systems are normal and stable by tomorrow.
Everything else is fine. In fact, more than fine as a set of very generous participants donated $6000 towards a new server that will become the new science database server. THANK YOU!! We're still spec'ing out said server, but will go ahead sooner than later now that we don't have to set up a funding drive!
Meanwhile I'm still chipping away at various data analysis projects, Jeff's been fighting with data syncronization issues that have been creeping in more and more lately. We also had a "design meeting" regarding where to go with the public involvement of candidate selection. I'm finding some plug-n-play visualization utilities on line, but pretty much I'm finding (like always) it might just be easier and better if I do it all myself with tools I already know. However, some improvements go beyond that scope, so I'm digging into AJAX which is good stuff to know, I guess.
