i copied this from anandtech forums (credit to hellburner) From the S@H page, get that setiq working!!!

"July 26th, 2000

UPCOMING OUTAGES:

Tomorrow, the router upgrade should happen. The outage is being advertised as starting at 13:30 UT and lasting 1/2 hour.

We will very likely have an extended outage on Monday, 7/31/00. We will post the time soon. This outage will last many hours, as it involves rebuilding the science database. When we rebuilt our database 2 weeks ago, expedience and available hardware forced us to rebuild in a less than optimal manner. Our entire db is now being driven off a single SCSI channel. Not very good! Monday's rebuild will allow us to spread the db over multiple PCI and SCSI channels. We will also arrange the disk arrays so that we can expand in a load balanced manner.

We apologize for the extended outage and for the inevitable but temporary sluggishness once we come back online. In the long run though, this should give the project a more responsive database with a larger capacity."


Just found this out on usenet:

"We've figured out the problem, which turns out to be all about how we allocated our mirrored devices among PCI and SCSI buses. The bad news is that in order to fix it, we need to backup and restore once again. That means an outage of up to 24 hours, most likely starting Monday morning (California time).

another outage coming. August 28, 2000

There will be a planned 2 hour outage on 8/30/00, starting at 13:00 UT. While the main reason for this outage is unrelated to SETI@home (Space Sciences Lab is upgrading the UPS configuration on all network gear), we will be using the time for hardware and software upgrades of our own.

Here's another outage:

October 18, 2000

The science database experienced what may be multiple disk failures. We are attempting a "quick" (~2-4 hour) rebuild. Stay tuned.

**Update, 12:02 AM, Oct 19, 2000**

Cause of downtime:

A few hours later... it went much better than expected. The drives were not actually dead but for some reason were marked as dead by the RAID controller. Two of the drives were a mirrored pair and thus that whole logical device was offline, bringing down the database. We were able to initiate a rebuild of the two "dead" drives, bringing them back online. There does not seem, at this point, to be any data corruption.
