Back in the Land of the Living
Well, our server crashed today. Weirdest bug I ever saw: we got a kernel oops when smartd tried to get health information from the drives in the 3ware RAID array. One of the drives appears to have malfunctioned, so perhaps that is related. The fragility was possibly caused by running a fairly up to date smartd on a fairly out of date kernel with SKAS patches… but it is far from clear. I need to test this out more to be sure of what the magic sequence was, but needless to say… it’s been an experience.
