Happy New Year!

We seem to have been running rather smoothly since last I wrote. And the servers were nice enough to wait until we were all back in the lab before going crazy. Well, it's not that bad - just lots of tiny problems. The astropulse science database server got stuck in some deadlock and needed a hard power cycle. Then I tried fixing this nagging db_dump problem (it hasn't regularly generating daily stats dumps) by moving the process from bruno to lando, and lando couldn't handle it - and I ended up needing to hard power cycle lando as well. Having lando reboot caused bruno to freak out a little bit as it was in the middle of a package update when lando disappeared out from underneath it. So I had some rpm database cleanup to deal with to get bruno to start upload results again. Oy!

Meanwhile we were bringing services up and down in a controlled manner to make some more science database tweaks on oscar. We're still deep into trying to figure out how to improve its throughput in general. We're finding the disks are still a bottleneck (even after the RAID restripe), but if we can get informix to cache more efficiently then disk i/o is less important. Or we'll add more disk spindles. In the meantime we have many knobs to turn.

I got the tracking # for new donated server "synergy" - should be here on Friday afternoon, so we'll start playing with it next week!

Regarding the weekly outages: we're sticking to the general idea which I mentioned recently - generally have our standard Tuesday half-day outage, and perhaps other planned one or two day outages as needed (with some effort to provide ample advance warning), but otherwise leave all public facing data services up and running as much as possible. However in the first sign of trouble, these services may be taken down for extended periods. The bottom line is you probably won't notice any difference between current operations and those from six months ago (before the weekly extended outages). The goal is to aim for 24/7 uptime while maintaining staff sanity.

Worth remembering some of that for the subsequent moaners we will encounter as time goes on.

I think everyone aims for 24/7 up time. Never down time. No matter how hard the team or anyone strides for it, at this point in technological time, it's just going to happen sooner or later, so lots o' luck with keeping everyone sane all the time as well.

Besides. . . All that constant sanity is sooo boring anyway. People should try inserting some unharmful insanity once in a while into their always serious lives. It helps unclog the old brain's drain. ;-)

Oh heck yeah! Exactly the type of area which wouldn't be safe and would most likely cause permanent insanity.
