What are the boxes set to do when power is restored after a failure? Stay off,
turn on, or return to whatever state they were in before? I'm asking because of
a possibility your statement brought to mind. I don't know about you, but I
live in earthquake country.[1][2] Let's say there's a major quake and breakers
pop. When they get reset, backup power reaches the boxes. If they come back up
and need to get thoroughly fscked, will there be an admin capable of dealing
with it?
Since these machines hold backup copies of data, hopefully they don't need to be
up immediately. If needed there will be someone present to supervise, although
if the RAID boxes are connected they could be powered on remotely, manually
fsck'd, and mounted.
My main concern is avoiding doing things manually which the computer can do for
me. It doesn't get tired, or bored, need bifocals to read serial numbers off the
boxes, etc. I like the idea of plugging in a box and starting the server, and
having everything just come up.
[1]Everyplace is earthquake country if you wait long enough.
[2]In my case, the San Andreas Fault.
