How > do you keep all those machines up to date if you can't take them offline? Maintenance time slots. A reboot after installing a new kernel takes less than 5 minutes and nothing else really requires a reboot, so this passes the Change Management process easily. Other updates are usually a service restart which can be done on the fly. So "never take offline" doesn't actually mean *never*, it means "outside agreed service levels" Fixing / means take the machine offline for X hours where $X is some large number depending on how big / is and how fast tar runs. And the Change Manager asks his usual horrible questions: What's the risk? What's the impact? Is this customer facing? Does this problem reduce quality of service to customers? Don't you have Nagios to manage exactly this kind of thing? His answer to my answers is usually something like "You're kidding me right? This is another one of Alan's pranks, right?" -- alan dot mckinnon at gmail dot com
