Broon's Bane (Dec 11 2007)

Okay so the weekly outage is running long and still going strong as I write and post this missive. So be it. What's the deal? I'll tell you. Short story: we're trying to get a lot done today. We fully expected things to take a while, and our expectations are being realized.

As we continue pushing forward on the analysis code, we needed to build another index on the master science database (thumper). This takes many hours, during which the table in question is locked and therefore the parts of the back end that require science database access have to be shut down, which is why we time such events with the regular outages.

However, we're also finally tackling the nagging workunit space problem. Our workunit storage server (gowron) shares workunit storage space with various BOINC database archives, so the easiest/best solution is to move those archives elsewhere. Where's elsewhere? We currently have a lot of space in a volume established for science database archives on thumper.

So today we had the two BOINC backups and the index build all hitting the thumper disks pretty hard, thus slowing everything down. Seems kind of silly, but this is a special case as we're not normally doing index builds. Nevertheless we'll move the BOINC database archives elsewhere at some point down the line as time/disk space permits.

Meanwhile.. we broke the archive space on gowron and converted it all into a bunch of RAID1 pairs which are taking a long time to sync up. Actually, there's even more ex-archive space available but we'll do that at another time. My guess is the syncing should be done around 3:30pm Pacific Time. Are you getting all this? Warning: this entire chapter will be on the test.

By the way, while waiting for all the parts above to come together I burned a Fedora Core 8 DVD and installed it on our latest Intel donation (mentioned in an earlier post). We're going to call it "bane" - actually reusing a name/IP address of another potential server donation that didn't pan out so well. I don't believe in jinxes, and I'm all for recycling. Anyway, it's already up and configured and working a lot better than the old bane. Might have a new web server racked up by the end of the week!

And we got the mass mail pipeline finalized. Maybe I'll start those up today too. This is actually the highest priority but it's not very good form to start a mass mail while the project is down.

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...

another good day...now we see how long we can hold back the chinese hordes

 

[petrusbroder]

Thanks for the stats, Rattledagger!

Good production - probably just temporarily - but good anyhow.

 

[Assimilator1]

Yep an excellent day for us

Man China's on a charge!:Q
