FIRST HARDWARE FAILURE On February 4 2011, Linux had reported that the third hard drive on the first server had failed. The faulty hard drive was pulled out of the server, replaced with an identical sized drive from the same manufacturer (in this case Hitachi), and the RAID array was rebuilt (a 12 hour operation). The server remained in operation during the entire crisis, and the channel's live video stream was never interrupted. Now because these servers use reasonably priced consumer hard drives instead of excessively priced enterprise grade hard drives, it's entirely possible there might be nothing wrong with the supposedly "failed" drive at all, and that it had simply taken too long to correct an internal error before the Linux software RAID controller had given up trying to access the drive. The hard drive will be tested to confirm that it is actually defective, and the results will be added to the show notes. I'll also see if I can get this drive replaced under warranty. While it was used in a RAID system, live video streaming is such an incredibly light storage task that the hard drive lights on the server only blink once every five to ten seconds. All of the real work is being performed by the processor, which is preoccupied with transcoding the video to a streamable format in real time. The workload subjected on these hard drives inside these servers is actually less than what you would normally see on a traditional desktop computer ...
