Ik hoop niet dat 't een grap is, maar we hebben vandaag een nieuw koetje in de stal!
Welkom HellBringer

Another Tuesday, another planned outage. We did the usual database compression and backup but it still took a long time as we're bloated with 2 million extra results waiting to be assimilated.

No big deal there, but of course we're still mired in the thumper projects. It's becoming a two-weeker (since the original crash the Friday before last). Remember we're fighting on two fronts: rebuilding the root drive RAID and rebuilding the pulse table. Starting with the former, all we (thought we) had left to do was install grub on one of the two bootable drives (even though the weird drive numbering causes grub to read the actual kernel image off a third, non-bootable drive). Before launching into that I rebooted the system just to make sure everything was working.

This system has very large ext3 file systems, and so I used tune2fs a while back to prevent a long (6-8 hour) forced file system check every 180 days (the default). Unbeknownst to us, it would *also* force a check every N mounts. So I was very displeased to find the system going through a round of forced checks when all I wanted to do was quickly reboot the thing. I was just going to let it go, but after a half hour I got sufficiently annoyed to just halt the check (gracefully) and re-tune2fs'ed to prevent this from happening again.

And upon coming up I was further displeased to find the only root drive (of the three) that appeared in the RAID was the one in the non-bootable slot. We're stumped as to why. Well, even though this RAID was seriously degraded, we powered down, did the planned drive swapping and brought the system up. Even though drives were swapped the only root drive this time in the RAID was the (new) one in the non-bootable slot. Fine. I'm pretty much of the opinion we need to reinstall the OS on this point to clean everything up, but until that happens we have some (oddly long) drive resyncs to un-degrade the RAID. Of course, this will all fail again upon next boot as far as I can tell.

Meanwhile, the pulse table reload that started yesterday failed last night. Since we have redundant database servers now, the informix engine is sensitive to anything that may bring the primary/secondary systems out of whack. This includes really long queries, like the one we started yesterday to copy 500 million pulses from one table to another. Back to square one. Jeff wrote a script that breaks this one query up into many smaller ones, thus hopefully circumventing any "long query" issues. We estimate this will be done Thursday sometime.

I did start up one assimilator - the trickery I mentioned yesterday (to let assimilation run alongside pulse table insertions) does work, however as the pulse table gets populated it eats up a lot of database locks, and the assimilator can barely get an insert in edgewise. In any case, I found a rich source of stuff to move off the workunit storage server, so at least that bottleneck will be temporarily alleviated.

Oh, yeah - end of the month, so that's the end of the current thread title theme. I think the only person who came close to describing the theme was QuietDad yesterday (apologies if others got it earlier). Anyway, the official theme was: Apple II hackers/game programmers who, as a budding young programmer myself in the 70's/80's, I thought were super heroes such that I fondly honor their names (real or otherwise). It takes a real game programmer to do *everything* - not just the game logic but also the design, the graphics, the animation, the sound, the music... and do it all in machine language (and 6 colors, including black and white, in 280x192 "hi-res" graphics).

Ik ben inmiddels qua WU's druk aan het afbouwen voor komende maand. Echter kom ik daarna wel dubbel terug aangezien ik een goede deal heb gesloten voor een Quadro FX van nvidia. Deze gaat dus volgende maand ook meestampen aan het SETI project Even weer wat inhalen vanwege de stampede

Mooo you later.
