We're still struggling to get raw data on line fast enough to keep up with workunit demand.

I should point out that the system that locked up over the weekend is an otherwise great file server that was graciously donated to us by Overload Storage along with continued speedy tech support and free replacement drives whenever we ask. The catch is that we're officially beta-testers on this funny version of the OS. So the system unexpectedly locks up, I dunno, once a year? That's more than acceptable as it's just a raw data storage server, and the upshot of a this system locking is, at worst, a temporary dearth of workunits. Even worse things can happen.

ALSO - more importantly - if this system didn't fail we would have run out of raw data anyway and be in the same boat we are currently in. Maybe even sooner.

Anyway... Another hangup was a cheap gigabit switch that fried a month ago and we replaced with a cheap 100 Mbit switch. This was being used to connect our non-closet servers with the closet. During the mega-outage, fast connectivity wasn't necessary. However, when we started to split/assimilate again it became apparent we needed to get that stuff back on a gigabit link. So one is on order, and in the meantime Jeff dug up a tiny 5-port switch so a few of the machines (that are splitting and running the software blanking suite) are talking full speed again to the closet. This may improve the workunit shortage situation over the next couple days.

Isn't it nice to have enough in reserve to be able to order what you need right away instead of having to wait to raise the money? Too bad we can't keep you guys flush all the time. Hope you had enough to order a really good switch.

Thank you Matt. I knew the running out of data had nothing to do with the drive failure. Different issues. As always the updates are very much appreciated.

Thanks Matt. If I may ask, just what make and model of switch did you order?

>So one is on order<

I was in BestBuy earlier tonight. If I had only known...

16 port gigabit for $199.00...

So, what did you decide to buy?

Whatever happened to get some work flowing again, I appreciate it. My machine is now working on a Seti and 2 Astropulses, and I see lots of them Ready to send on the Server status page. So now I feel comfortable letting it have some Einstein again too.

Was anyone besides me unable to connect to the web site this morning? I want to say it was around 0800 CST. I could get, but not setiathome. with or without the ssl.

Matt, first, thank you for all the hard work to get things running again. We all appreciate it.

Second.. can we get validated tasks to stay listed for 24 hours again, or at least 12? I know that's not really a show-stopper or anything, but it sure does make it easier to spot validation errors and such.

Awesome job guys, work is flowing again and it appears we have a backlog of WU's waiting to be downloaded and crunched! Keep it up and thanks for the updates.
