Speaking of braindead filesystems, a few hours ago, I had a nasty power outage that my UPS didn't catch (batteries appear dead despite monitoring tell me they are all A-OK. But it has been 3 years).
I've seen UPS's at around 80% of maximum load suddenly decide that they are overloaded the instant the power goes off. Apart from the above, someone decided once upon a time that with redundant PSU's on a server it would be a good idea to plug one PSU into the UPS and one directly into a mains outlet in case the UPS failed. This is stupid and also results in the above situation. James
