In case you don't know the replacement server will arrive on Friday. Most likely it will arrive that morning down in Menlo Park but somebody will have to shlep it up here, which leaves little time for much progress unless we all stay late. Of course, Friday is the day that Eric and I usually aren't in the lab at all. I got a couple hectic gigs this weekend (one Friday night in Oakland, the other Saturday night in LA) so I definitely ain't comin' in on Friday.

Anyway, this all means Monday at the earliest we'll get the replacement server up and running. We're hoping we can pop the disks from the dead server into the new server and get rolling rather quickly. If it doesn't work for whatever reason, we do have backup tapes of the database and can recover from those. We were planning on getting a separate compute server containing a replica of the science database. We're actively pursuing this as well. We would have had one already except for lack of time/money resources.

Meanwhile, I came up with a novel plan this morning - with some creative hand waving we could trick a non-SETI informix database into being a temporary s
cience database which could enable us to at least create new work until a replacement server arrived. One major drawback is this particular server crashes all the time with unknown results. Such a hack would also add some significant cleanup to do before employing a replacement server. Nevertheless, we're sleeping on this plan tonight and may very well enact something tomorrow. Don't hold your breath.

Just checked FedEx tracking (via a vendor-only system). Not much resolution when the thing is in transit. The replacement Sun server is on a truck somewhere between Memphis and San Jose.

So it's been a relatively peaceful day. I've been mostly getting all these dozens of services, cronjobs, scripts, web pages, etc. off of koloth so we could retire this thing already. Each one seemed to involve a nested problem exposing broken paths, bad httpd configurations, misaimed sym links, etc. Fun. And the kryten system is basically out the door except I'm keeping it around in case we need extra splitting power when the floodgates open.

I think we all understand Matt. It's just one of those things. Keep up the good work.

Matt, make sure you play "Bus Wreck" ... and dedicate it to the old server.

If the new server was not keeping the name "Thumper", you could name it "Elvis" (Sun, Memphis).

Did you see my suggestion in previous Tech News thread about re-sending all WUs early that have not hit quorum yet ? I'm sure there must be quite a few "ghosts" out there that will time out in the next few weeks.

Hope all goes well in the next few days,

Keith

The updates are great. Just keeping the community informed means everything. I wish it was the same way on some of the other BOINC projects.

I still can't believe the fuss a few people kick up about this- talk of uninstalling/detaching on their whole farm....
Bad luck on the delay :( Hey I might even finish a whole run for climateprediction.net :p

Thats okay, it gave me a chance to do some protein folding. Until now, I've only done SETI. Good luck, and thanks!

Gigs?

I haven't heard that word since, well, the 60's.

Eric, are you as old/older than me or doing the retro :)

Had doobies back then too and they weren't the Doobie Brothers either :)

That term is still used quite frequently by upcoming musicians. I hear it all the time.

Come on Ozz, I know it's still used. ello?!

Simply though, it goes back to the "hey man (replace "mon" too), I got a gig going on at the happening place". (add the appropriate accent (reggae) Bob Marley and the Wailers)

Been there, done that. WoooHooo

Oh, "Hey Dude" wasn't a phrase yet back "then", but it would have been used if someone had thought about it, lol.

I thank you all at the SETI foundation for all your efforts. Matt, you are awesome!! I've donated $25 bucks here and there, I wish I hit the lotto so I could make a difference. I know you guys will get it going asap, thanks again for all of your dedication and efforts. Ron Couch, Mira Loma, CA

You have made a difference. If 10% of the crunchers donated $10, it would fund SETI for a year. It takes very little to make a difference.

Why not FIX the dialup interface portion of the boinc manager while you have all this time ?? It hasn't worked properly since the last updated version was released.
