Saturday 6th July 2013: 1.13am. Got an email from my new monster dedicated Canadian server today to tell me its second hard drive had failed, and it has fallen back onto its last remaining mirror drive. This sucks, because now I have to copy ~20Gb of stuff off before I can ask tech support to replace the bad drive (in case they replace the wrong one, which can and does happen).
Copying ~20Gb of stuff away (over the Atlantic) takes quite a long time unfortunately. I'm guessing it'll be done by tomorrow morning.
Thank you RAID-1 though for saving all the work I have invested so far!
