I apologize for naming this thread the same as 1987 Bruce Willis oeuvre, but such things cannot be helped.

Last night there was a "perfect storm" where 3 of the 4 splitters barfed, and we ran low on work to send out. As a reminder, the splitters are the processes that make the actual workunits we send to the clients. The one remaining splitter that stayed afloat kept the traffic from completely dropping to zero, but still there was some cleanup necessary this morning to get things back on track, including a reboot of kryten again.

Speaking of kryten, Eric got the new server assembled, and Bob came up with the name "bruno" in honor of Giordano Bruno - a monk who in 1584 proposed the existence of "innumerable suns" and "innumerable earths" with living inhabitants. He was promptly burned at the stake, though it is argued whether there were other reasons for his roasting. Anyway, the server is up and its disks will be stress tested all weekend. I just configured the last remaining odds and ends of the OS so that we can log onto the thing.

Early next week Jeff and I will break out the machetes and start cleaning out the server closet. We have some cable rerouting and power mapping to deal with before we can put the new servers (bruno and sidious) in there. Sidious is an addition to the server complex, where bruno threatens to take over the roles of up to four other machines - koloth, penguin, kryten, and galileo - though we'll be happy if it only ends up replacing kryten.

There were still some lingering issues on the boinc.berkeley.edu web server (isaac). Certain web pages were hanging for inordinate periods of time. The trail of guilt started with mysql, which led us to php, then to apache, and finally to sendmail. At this point I was stumped why mail was being a problem, and brought Eric and Jeff in to look over my shoulder. We were all flummoxed, but eventually we found that the loopback interface had no IP address assigned to it. Hunh?! Turns out this particular install of the OS failed to include the boot startup script for the loopback interface, and therefore no service could connect to localhost, hence the mail issues, etc. That ate up a couple man hours.

Congratulations to all of you for a job well done! I KNOW how much work those kind of problems can be. I, for one, am glad you got all that done in just one day!

Actually there is more! There are many Seti Users that have contributed to Bruno and other Seti upgrades... Some items are waiting for "timing" to get things in place... There is more still to happen over the next couple of weekly outages...

Thank You, to those that have found or purchased Hardware!!!!

More is still needed Donate Hardware II I am still working to find the best deal on the FiberChannel drives for the NetApp Filer that has the red lights...

Thank You Matt for Sharing about Bruno...

Hooray! Bruno will do quite nicely, It seems a 4 to 1 or 1 to 1 replacement doesn't matter much to Me either, 1 is good enough, But If Bruno will replace 4 then that's some real gravy as maybe It would also reduce the power consumed there maybe and therefore money spent on power possibly(at least I'd hope so). In any case Good Job Guys!

In this latest incarnation Bruno will certainly help us to find "innumerable earths" going around "innumerable suns" hopefully with people more intelligent than ourselves (OK, I didn't set the bar that high, but one must start somewhere).

As usual, good work Matt & Staff, and thanks to everyone who donated their time, money or parts to make this happen. Keep on crunching!

Regards,
Wander

Matt, if you need any manual labor-type help with the server closet move, I'm both: available, and close enuf to SSL, to be of use... see my account 8300337 for my e-mail.

It's almost like New Years eve, where we are waiting for the era of Kryten to pass and the era of Bruno to begin.

Good bye Kryten

Hello Bruno

A huge thank you to all who have donated money and/or hardware to make this change possible. We all owe you a lot.

Hi Matt

Thanks for the update.
I am glad to hear that kryten is finaly going to be laid to rest. ;-D

Are you teaching the kitten to play the guitar?

Thanks again to you and the rest of the gang there for all your hard work.
