I added some instructions on disabling the shutdown in response to the power button. That would be something to try.

comment LVM snapshots as a backup strategy
There's a few points in your description which I think are incorrect. In current versions of LVM, if a snapshot becomes full, it's simply marked as unusable and needs to be deleted. I/O on the device does not get halted. Secondly, when you delete a snapshot, no data is copied back to the original volume. Essentially, when you write to the live volume, the original blocks are first copied in to the snapshot, and then the live blocks are updated. Then when you drop the snapshot, it's just a matter of removing the entry from the device mapper. No copying required.

comment UPS and power strip interactions?
Does that also exclude rackmount UPS + PDU? Typically the UPSs are placed at the very bottom of the rack due to weight, then you need some way to give outlets to servers unless you want to run a whole bunch of really long power cords :/

comment Best system administrator accident
A good reason not to rely on "cd" in any kind of script. Always use the full path expansion.

comment The perfect server room?
As someone who has rolled a loaded 30U rack on to a truck, it's definitely not something I would want to do ever again for any reason. It really messes with the elevators having that much weight on the rack, and the moving companies aren't equipped to deal with it, even if they are. We tried this when we were moving offices and I have to say it was the scariest experience of my professional life, watching the rack containing all our expensive equipment getting loaded on to the back of a huge truck and bouncing around on the pavement in the process. Better to unrack your gear and move it.
