Long day at work today. I was halfway through some rather delicate changes to a 90TB storage array, when the power cut out to a decent portion of it. The ensuing fountain of profanity caused the ex-marine sitting in the same room to perk up his eyebrows and say “wow.”
Long story less long: There were crappy power strips with a 15A breaker, in between my 20A of load and 20A outlets. I had been “reconditioning” the drives, which involves spinning them all pretty vigorously. 20A would have been plenty … but 15A was not.
This is not the configuration in which I left the system.
I called in my minions and demanded (a) extension cords (b) a trash can. They were all like “wha?” I said: “Extension cords catch fire, rather than cutting power to my very delicate and moody SAN. This would be preferable to just powering off the hardware for no reason. If you’re going to hack my system, I want it to endanger your lives. I plan to fill the trash can with these crappy power strips and then force you to take them to the dumpster out back. Questions?”
In other news, Apple’s XRaids do not automatically map around bad blocks on the disks. You have to kick this process off by hand. If you do not do this on a regular basis, you may be totally screwed.
We may or may not be totally screwed. I will know in the morning.
On a final note: I am that guy at the bar with his laptop. I believe that I shall order another beer.
