[SETI@Home] hitparade van 9 december

Aangezien ik niet zoveel weet te melden, en jullie toch bezig wil houden komt er maar weer een raad-het-plaatje. Deze keer is 'ie niet zo moeilijk, met google in combinatie met de naam van de foto moet je een heel eind kunnen komen... En als je dan het raadsel hebt opgelost, weet je ook waar je die mijlpaal kunt ophalen

Tuesday outage day (mysql database backup/maintenance). Today Bob took care of the final step of the "single vs. multi-dimensional indexes" exercise. That is, he dropped all the multi-dimensional indexes on the result table in the main project on the master database and we crossed our fingers. Looks like mysql is neatly, or smartly, parsing queries and merging single indexes as needed just fine. This whole point was to remove the number of indexes we need, and thus keep a slightly smaller footprint in memory, which in turn helps performance.

The raw data pipeline has been a major headache, if only because our hot-swap enclosures have been giving us grief. Jeff and I determined one of them is flat out broken, so that reduces our current maximum throughput by half until we get it replaced. This isn't a disaster, as we pretty much never reach half of our maximum throughput anyway, but still a slight inconvenience as we have to more rigorously schedule drive swaps.

Gearing up for the donation drive, I discovered our mass mail server lost its DNS entry for some reason. The lab DNS master replaced it, but not after I turned sendmail on an hour earlier and started my tests, thus causing all kinds of circular bounces that clogged the entire lab's mail queue with literally thousands of e-mails (maybe tens of thousands). It's still draining as I type this. Don't blame me - I didn't remove that DNS entry.

We're another step closer to removing that NetApp box. In fact, it's out of the automounter maps, everything on it is sym-linked elsewhere or chmod'ed to 0, and I scoured all the other servers to remove sym-links to it. Part of this project meant resurrecting server "clarke" (donated many months ago) to be a CPU server (or otherwise internal use) as it will soon have room in the closet. It had a stale configuration at this point which needed refreshing.

No news on the Overland boxes - though one question was: why not combine them into one big box? Well, we have two separate needs: workunit storage, and raw data storage. The former we already have, and it works great - we just need more room - so we'll plug in one of the new expansions and get that room. The latter we don't really have and would like to keep on separate volumes (as you read the raw data and write out workunits, so you don't want the I/O to compete as it would on shared drives). Also.. part of the deal is we're going to continue helping them beta test their latest OS, which they have on the second head unit they gave us. So in a sense we're obliged to have two separate entities - the raw data on the beta test head/expansion and the workunits on the known-reliable head and additional expanion. Other question: form factor - the heads are about 2U and the expansions are about 3U. We have 2 of the former and 3 of the latter now. We'll have room for them eventually. I will update closet photos when we do the next major move (next week, I hope?).

Huûsdune bij Den Helder!

Dat kon wel een eind rijden worden voor de mijlpaalophalers.

Ondanks dat, feli Mr Beamer, K3th3r en ronald meulen.

congrats to all mijlpaalers en sucses met het ophalen

Heb je daar zo lang over moeten puzzelen?

Oh, even een kleine mededeling: al het werk wat ik teveel had gebufferd voor de SSSF is inmiddels op. Momenteel ben ik even aan 't bijklussen bij WCG, dus van mijn kant even wat minder punten.
