[SETI@Home] hitparade van 26 november

[grass460]

hmmmm 21.15 uur en nog geen stats.
Ben net terug van het werk, dus dan maar even gauw posten.

Laat ik maar aftrappen met de mijlpalen, en wat voor een mijlpalen zeg. Dammm hansR onze grootgrutter pakt die van 20miljoen, jaja jullie lezen het goed. Dan mijn eigen team Division_Brabant dat de 2miljoen paal pakt ook niet bijzonder slecht. Sjowhan Smiley Maartenvan der Blij en Maikel uiteraard ook van harte proficiat met jullie mijlpaal. Jullie moeten hem zelf ophalen want op dit tijdstip vind ik geen pakketdienst meer.

Oh well, we tried. We thought we would just have to put some extra minutes monitoring the data pipeline over the weekend (after wasting a lot of time bringing up many broken files), which wouldn't have been too bad, but...

Then bambi crashed last night - it's our secondary science database server but also manage a lot of the data pipeline stuff. I happened to be free so I drove up to the lab around 10:30pm and rebooted it. After that, the pipeline zipped right along.

That is... until 11pm when the router up and died. Or something along the entire Hurricane Electric network path died. We have no idea. Jeff and I fought with it (both remotely) this morning, but we're throwing up our hands at this point and going on holiday.

Might as well have everything fail at once, and at the start of a long holiday weekend. Why not?

Okay then. The mysql commit behavior we were testing was an absolute failure - though for expected reasons (not enough disk i/o, even with the solid state drives). It was worth a shot, but we fell back to the old commit behavior for now.

However, this caused a lot of backend processes to clog up including the transitioners, which ultimately meant the splitters burned through all kinds of raw data files before they realized we had more than enough work on disk. This could have been bad, i.e. filled up our workunit storage server, but luckily it didn't even come close to doing that.

Anyway, we reverted this morning and all the dams broke for a while... until we ran out of work to send out. Turns out the last 10 files I brought up from Arecibo are all broken. <sad trombone>Fwa wa wa waaaaa</sad trombone>. This is particularly frustrating as I was busting my hump trying to get enough work on line before the long holiday weekend, and now we have zero. So it'll be to me and Jeff to check in over the next few days and kick the pipeline along. We'll be out of real work to send out until this evening at the earliest, and quite probably hit long periods of no work throughout the weekend. Fine.

In better news, we did the last bits to get the Astropulse signal table fully copied over to another database fragment - only losing a few rows here and there (as opposed to many thousands as originally thought). Work will resume on Monday to make this exchange old/new fragments and hopefully the science database will be much happier.

That's it for now.

At the end of the day yesterday our raw data file server lost a drive. The bottom line as far as you're concerned is that we had to stop the creation of workunits until we got on top of the RAID resync issues this morning. But by then we were into our normal weekly outage, so you've been unable to get any work for a while, and will continue to not be able to do so until I start splitting up again - probably later this evening.

Meanwhile, every other part of the project is coming back online. We're testing the new mysql commit behavior (mentioned in yesterday's post). It's not looking good right out of the gate, but that may be due to mysql needing to read everything back into memory again after a bounce to pick up the configuration change. I may have to bounce it again if it continues to be a problem. I hope not, but it's no big deal either way.

Looks like Bob got most, if not all, the corrupt astropulse table finally copied over to another table so we can drop/recreate the data and get rid of this corruption (which has been causing us random headaches over the past month or two). I just ran some preliminary tests on the data integrity. Looks good.
