61) Message boards : News : Slow server for the next 8 hours or so... (Message 1978200)

I think your math is off a bit.

700,000 * 710 kB = 496 GB

It's actually quite a bit more than that because the residence time of workunits is at least a day and we're pushing through about 1.25M per day these days. But's still less than 1TB.

In practice we use one 10x2TB RAID-10 for the data coming from Arecibo, and temporary storage of database backups, some other data sets that have low access demands. We use the other 10x2TB for outgoing workunits and little else because we want the full I/O capacity of the drives to handle the workunit transfers. If we moved to another system I'd probably want a triple mirrored set of 15 drives, or a move to SSD. Given that the space keeps getting rewritten, SSDs might not have a long enough lifetime.

Thanks Eric for the news. Out of interest are big is the storage capacity in George M?


Not huge. Two RAID-10 arrays each with 10x2TB drives. So about 20TB usable.

GeorgeM, the machine that holds the data that you download, decided that it was time to verify that the RAID array is in good shape. That will slow down disk access until the verify procedure is complete. The main effect is slowing down the rate at which work can be created. It's likely that we'll run out of work in the next hour or so. Things should recover automatically when it's done.

While a lot of the dates are 2006, some are 2011 others are 2016. Most of these have log entries claiming they were done, but none of the results are in the database.

Well, I can't fault Parkes for doing what is asked of them by the folks who provide their funding. We've always been an "along for the ride" project. My understanding is the delay will be months, not years.

Unfortunately, Parkes took down the multibeam feed we were using for the galactic plane survey and put up the wideband feed. That put a bit of a hitch in our plans.

You may have noticed occasional bits of data from years past showing up in your queue. While running a completeness check I noticed some files that had never been completely analyzed. Some may have fallen through the cracks. Some may just be bad data that never made it through the splitters. I'm going to trickle them into the queue when the Arecibo queue is empty, just in case.

We've had screen saver problems on both Windows and MacOS. With the advent of flat panels, Microsoft and Apple apparently don't consider maintaining screensaver compatibility to be a priority. We might have to change the whole screen saver architecture in a future release.

We had a minor science database crash today that brought work generation to a halt. Everything appears to be OK with no data losses. We should [be] entirely back up at this point, but I'll keep checking things out.

And as of today, https://www.gridcoinstats.eu/project doesn't show SETI@home as a whitelisted project. I assume it's a mistake because we have been continually generating credit and stats. If it continues I'll look into it.

The server Centurion handles the Green Bank Telescope data, do we know yet what the Parkes data server will be called?


The server is named "amigos." It seemed appropriate since the bulk of the funding came from three people.

We've started our 2018 funding drive. Many of you have probably received our email penned by one of our undergraduate researchers. If you can't wait, you can read yours here.

Because we're not yet fully GDPR compliant, we're not sending emails to anyone with an EU/EAA email addresses, anyone who listed an EU/EAA country, or anyone who listed "International" as their country. And, of course, anyone who has opted out of our emails won't get them.

Thanks for your support!

We've finally got the BOINC account deletion feature installed and enabled. Account deletion cannot be undone. You'll also need your password and a valid email address for identity verification.

You can access it from your account settings on the web site.

I'll look into it. The UCB Data Center switched to a new firewall configuration. That could have something to do with it.
