Far too early

I was awoken with a hangover and what sounded like an alarm in the background. Strange I don’t have one that sounds like that. I was hungover from Reitschule but not that hungover as to forget what my alarm sounds like. Next I thought it was my laptop beeping. No, that was next to me on the bed and in sleep mode. I got up, the head hurt even more and figured the building’s fire alarm must have gone off. The noise was coming from bunker, my main server. It was the sound of a disk drive continuously resetting:

I shut of the power to the offending disk and it now rests in peace. 3 years of of a Cyrus mail spool have taken their toll.


Acutally I think it has been the heat of this summer that has been cruel to the disks. I thank the RAID gods every day for the way in which my disks have failed over so smoothly:

I don’t like doing any big system changes before I go away and I am in Austria this weekend. I’ve been planning on doing the “big disk upgrade of 2006” afterwards, have the disks priced up and just need to pick them up from Bauers on Monday. The net result should be 1.2TB (4 x 400GB in RAID 5) of usable storage on the “/mnt/vault” array and 200 GB on “/” (3 x 200Gb in RAID 1 with hot standby). In the mean time I am going to hope that the single disk failed raid array holds up over the weekend.
