View source for Drive Crash 4: Now That's What I Call rsync

At the end of the 2016/2017 academic year, during weeks 9and 10, [[Sam Willcocks]], [[Tom Lee]] and [[Matthew Stratford]] decided it would be a good idea to tear everything out of the AV and Computing racks {{See also|The Great Tech Redo 2017}}. Unfortunately, some of the servers didn't like being turned off and moved around and decided to fail.

The first server to complain was backup, which complained of a degraded array. This was caused by a [[docs:Glossary | High Impedance Air Gap]] between the hard drive power supply and the drive.

Shortly after plugging the drive back into backup, Web started to complain of a drive reporting SMART errors. This drive was replaced and Backup, not to be outdone by Web, decided to destroy one of its drives. This drive was replaced and all was well.

=The Attenborough Disaster=
Matt and [[Tim Bradgate]] were happily patching cat5 when Tom (who was patching SDI in the AV rack at the time) noticed a suspiciously familiar beeping noise.

The general reaction was "oh crap, not again".

[[Edwin Barnes]] was asked to stop editing so we could shutdown Attenborough and the dead drive was identified as one of the OS disks. The disk was replaced and the array began to rebuild so Tim turned his attention to determining why the drive had failed, whereas Matt and Tom went back to patching the AV rack.

Tim determined that the drive was healthy, which was slightly concerning, but more concerning was the beeping that started to come from Attenborough.

At this point #Computing moved up a level of emergency.
