Technical News:
07.02.2007
So today was a usual day until the mid afternoon. Eric got a new RAID card (as well as a set of 8 750GB drives) to add to his server ewen, which is strictly a hydrogen survey machine. I helped him pluck the heavy machine from our server racks and place the new drives in trays, etc. The drive trays required unusually small screws, so Eric disappeared for a while hunting around the lab for such things.

Meanwhile, some SETI servers were locking on ewen being off the network. It's a tangled web of network dependencies around here, as you know. And then upon turning the machine on we had to wait a few hours for the thing to build a 4 terabyte RAID array before we could boot the OS and free the stranglehold it had on random machines.

This didn't affect the public projects - it just made it hard to get any work done. But the following was worse. So I'm gearing up to upgrade isaac (the boinc.berkeley.edu server) and was inspecting its empty drive slots when I noticed that gowron (not the download server, but the download *file* server) was rebooting. I must have accidentally grazed against the touch-sensitive power switch right on gowron's front as I was messing with isaac which is right above it in the rack. Well, dammit.

Normally, this would be no big deal, but upon coming back up kryten and penguin (the upload and download servers) weren't given permission to mount it. In short, I uncovered either a bug in gowron's OS or some newly broken configuration, or both. Attempts to set things right required reboots at each step, and one such reboot triggered an entire RAID resync, which normally takes all night (when the project is inactive - several weeks if the project *is* active).

So great. I went home dejected and hating my job. Eventually I checked back in and found the resync of the download partition actually completed, and even though other lesser-used partitions were far from done I found a way to somehow trick gowron into letting kryten and penguin mount its partitions, and voila! The project is back up. As I write this missive gowron is still resyncing and people are connecting and getting work just fine.

Over the past few days we've been trying to get our download server (penguin) onto a new network. All kinds of confusing issues as this involves two new routers under our control (one here at the lab, one down at the PAIX), and several third parties along the way. The map of the route, currently on the dry erase board by my desk, is a bit, well, complicated. The question "why are we doing this" will be answered once we are successful. Currently, while one of our web servers is on this network, we can't do much else. The download server is hitting a bottleneck somewhere along the way that has yet to be discovered.

Meanwhile, kryten is still being a whiny baby. Last night I cranked up the number of apache listener processes to help quicken the pace of outage recovery, but I never had to resort to this before. Another mystery.

As I write this, things are a bit off, and we know this, but we are trying to collect some more diagnostic data about the new network before "falling back" for the rest of the weekend. More surgery come monday.

Appart for Anandtech's stats, it shows how much more/less than Anandtech.
Also shows based on Average Work Done how many days for Anandtech to overtake the team, or be overtaken by a team behind...

Thanks for the techical news (very interesting - I've had just a wee of trouble uploading finished WUs and downloading one new one, which is not a lot considering that 18 comps are crunching Seti@Home) ...
Thanks for the sTAts too, Rattledagger! :D :thumbsup:
