Message 1060097 - Posted: 27 Dec 2010, 3:00:03 UTC - in response to Message 1059940.  

Well, Server Status Page is dead since 2 hours. It shows 18:40:08 UTC, and that's 2 hours ago.

Upload servers seems dead in the water though, requesting and reporting jobs seems to work though. I do not know if actually being assigned jobs and downloading them works, because my computers do not need any more work right now.


I got home from my Sunday volunteer job about 20 minutes ago. As soon as I got my laptop plugged in and enabled network, my BOINC manager requested and successfully downloaded 1 MB workunit. However, I have completed WUs on both boxes that are on 2+ hour backoff to upload. So the Scheduler and Download servers are working, but the Upload server is not.

But I have 1 WU in progress and 1 waiting to start on each box, so I am good until at least Wednesday. Matt and/or Jeff will fix it in the morning.

Even with two new servers, and one on the way, around here, Patience is not just a virtue, it is a necessity.

Maybe this has been covered elsewhere, but when the third new server comes online, will the mid-week outage be a thing of the past?

Not that I'm an expert or anything, but it seems to me that if the splitters generate WUs and the d/l server delivers them and the u/l server(s) receive the completed ones, the integration of completed and validated results into the database could be deferred for a while, although this might take a lot of storage to hold the WU's waiting for assimilation. It's possible that validation could even take place off-line to the main database. Unvalidated WUs likely aren't "fully" in the database anyway (I think).

But perhaps my basis is wrong, and assimilation is not the reason the database is not used for science except mid-week.

Or perhaps what I'm suggesting is already happening and there is no longer a scheduled mid-week outside communication shut-down. I don't see the mid-week notice on the front page just now, although not until Tuesday would it be needed.

Whatever, hi folks. Keep on crunchin'.

Matt addresses that issue here. There will still be a short weekly outage for Database maintenance, but the 3-day outages should become less frequent and/or shorter once the new servers are all settled in.

I can't believe that anybody could complain about too much here lately.
We just had one of the best server runs in a long while.
Almost made it through the long holiday weekend, and work was flowing well enough that most folks should have been able to fill their caches.

In about 6 hours somebody should be back in the lab and get their kicking boots on to resolve the problem.
It will be interesting to find out what brought things down.

My guess is the campus router power socket was needed for a photocopier during a Christmas party that got out of hand :)

I agree with Mark here.
Caches are full of work so nothing to worry about.

Don't see the problem here. I've had pages and pages of stalled transfers before and the always get cleared up. If you keep your cache large enough to bridge through these minor inconveniences, then you will eventually get the credit and have plenty of work.

If you can't stand that, then move to another project. If you keep a couple of projects on your list with zero % resource share, then should the unthinkable happen and you run out of SETI units, your BOINC will switch to one of those other projects.

For me, the happy balance is CUDA for SETI and CPU for AQUA, with Einstein on reserve. Plenty of work, plenty of points.

Just take a chill pill. It's all good.

Servers went down....no uploads or downloads right now.

Should see some activity in the next couple of hours hopefully.

No outbound work yet....
Server status shows mostly red. Either they have to reboot servers to put things back in order, or they are just waiting until the backed up download traffic settles down a bit.

Look at the Server Status Page now (almost entirely red), and then come back saying the same :-)

I am starting to see some credits granted to my total....

Matt just posted in tech news about the problems.
Might be a bit hurky-jerky until tomorrow's outage.
