One of the reasons sysadmins have old servers out there that still have |
34 |
huge uptimes, is that we dare not switch them off. We don't know if the |
35 |
drives will spin up again from cold! |

Technically, we should do a power down test every 6 months or so, but |
38 |
that turns out not to be a yes/no test in real life; it's a yes/destroy |
39 |
test and no-one wants to make a decision either way. So we all sit in |
40 |
limbo and wait for some exterior event to decide for us (like black-outs) |
