Yesterday (Monday) there were an emergency generator test which affected the whole lab. Even though this test was mostly for the benefit of another project here at SSL, this still meant we had to power everything down, wait for the test to complete, then power everything back up. For the most part it went okay, but we had a few casualties on the way back up. A small subset of outlets on the back of one of our UPSes failed (a broken internal breaker?) - not a big deal. Dan's cheap desktop system also mysterious died, and won't power on anymore. That's a worse problem, but not a showstopper. However our scheduling server, bane, failed to boot. This seemed like an OS install problem, even though we had successfully rebooted it before after upgrading it the other day.
Luckily we have synergy in our racks, and it took me less than 10 minutes to configure it as a replacement scheduling server. But before I take any pride in that feat I admit that some internal server errors were getting lost in the noise upon bringing the projects back on line. Turns out a max request size setting for mod_fcgid was high by default in the older OS on bane, but not as high by default in the newer OS on synergy, so we needed to set that explicitly by hand. Fair enough, but all evening a set of crunchers were finding it impossible to connect and get work. I fixed that this morning before the standard weekly outage.
Also it should be noted a bookkeeping cronjob running on bane (now missing with bane out of commission) caused the splitters to run out of work overnight as well. This also was fixed this morning. We should be more or less back to normal after we catch up for a bit. Sorry about all the workflow hiccups.
Meanwhile, what's up with bane?! I spent half the day today installing and resintalling the OS, thinking I'm getting on top of the problem each time, but nope. Seems like the Fedora 16 installer has some issues in general, compared to previous versions. Yeah, I know, we should be using
New server-wise, I just checked the tracking info. Looks like they will arrive on Thursday.

and cause that, Bane will lost his job and will be laid-off :(

I hope you have been informed by now that things are NOT flowing nicely.
Lot of crickets available, not as much work going out as should be.
Perhaps Synergy is being taxed by so many tasks allocated to it?
Or some more settings needing tweaking.
Whatever the case, work is not flowing as it should be.
Thank you if you can find the answers.
And hopefully the new hardware inbound will ease your duties, once properly commissioned.
And meow from the kitties for your hard work, my friend. Not unappreciated.
Excuse me if I am hard to understand at times.......I've had a difficult few lives.
