goede middag welkom bij weer een set verse stats
drie mijlpalen te vergeven te weten aan
muppet99 , Apollo13 en base.sg gefeliciteerd alle drie
daar alle diepladers bij schiphol ingezet zijn moet je de mijlpaal zelf komen halen in het zuidoosten van nederland
de gene die een stalfeest mag organiseren is vandaag bpenris omdat hij FOTD is geworden

hierbij nog wat nieuws van seti voor de liefhebber

Lots of machine rebooting today as Eric is getting his new hydrogen server online, and I'm finishing work on moving mail servers around. This shouldn't have affected the outside world. During all this Eric gave Jeff and I a quick tutorial on merged file systems. Wacky stuff.
Radar wise, I got some lengthy notes from Phil down at Arecibo. Turns out by far most of the radar we see is from the airport, which was news to me, and that's the only thing the hardware blanker checks for. Discussions will continue.
Dan, while at Arecibo earlier this week, replaced our non-working raw data drive enclosure with one we've been using up here. It's unclear whether this helped or not. We're learning that SATA drives (and enclosures/backplanes) aren't necessarily meant for excessive hot-swapping, and will fail after N "mating cycles." This may be what we're coming up against.

Tuesday means weekly outage day. Nothing really interesting or scary today. The only sysadmin thing I did during the quiet time was moving mail service off one machine (which we plan to retire soon) onto another. Still have a couple steps to go on that front.
I should mention that we upgraded our network connection from our auxiliary lab to the server closet from 100Mbit to 1Gbit. In practice this meant simply replacing an old cheap switch which a new cheap one. This was mostly for the benefit of Eric and his new compute server, but on the side helps vader (which handles half the downloads and all the assimilators) and our other compute servers maul and marvin (all of which still sit in the other lab, awaiting room in the closet).
Finally stopped being sidetracked enough to work on radar blanking again today. I'm finding some data is very clean and would like to not enforce blanking if it seems unnecessary. E-mails were sent to the experts for advice.

Happy Monday, everybody. It was a pretty smooth weekend, so not much to report there. Today I mostly took care of chores and the less glamorous/interesting side of systems administration. Eric bought a new server for his hydrogren projects. We needed to put it somewhere, so we decided to put it in our current auxiliary rack, which is currently sitting in our other lab waiting to replace one of the smaller (and less useful) racks in the closet. One of the download servers (vader) is actually in this auxiliary rack already. Anyway, we discovered that yet again the rails for this server are ever-so-slightly too big given the current rail configuration. Annoyed but determined Eric and I put forth the effort of taking vader out of this rack (which is why it was offline for an hour there) and adjust the stupid rails. Now everything fits. Good.
To answer PhonAcq's question ("Now what is on the agenda to improve things to the next level of performance??"), there is always some looking ahead to what we'll need soon. First up is more memory in our mysql server (jocelyn). When all is well it can easily handle a mixed bag of 2000 queries/sec, but during peaks or other crises it may start to page and cause massive disk i/o. Given the current memory configuration it'll be quite easy to add 4GB ram to the system, which will help. Of course we're simultaneously scanning different avenues of download/upload bandwidth increase. We still have yet to do the whole project of converting thumper's RAIDs from 5 to 10, which will boost science database (and likewise splitter/assimilator) performance. There's more, but that's a good start.
