The addition of 16GB of memory to the database server caused an unexpected problem. It exposed a bug in the 3ware Linux disk controller driver which took many hours to identify and understand. The project was back up and running soon after 13:00 UTC today. We do not anticipate any further issues, and apologize to project participants for the unanticipated downtime. On the positive side, the memory upgrade will make the Einstein@Home web pages and project forums snappier and more responsive.

There was a disk failure in the Einstein@Home project server on February 17 at 20:47:08 UTC which was handled correctly by the RAID controller hardware but not by the OS driver, resulting in an unwritable file system. This was fixed by David Hammer within about five hours. During this time, file uploads and downloads were not possible. About two hours after the disk was replaced and the file systems was repaired, a bit of fussing was also needed to restart work unit generation and the scheduler. The project is now up and running again.
