like temperature and line voltage. It's plugged into a UPS. I want
it to last as long as possible when power goes out.
I want to spin the disk down to save power. But there is a lot of
activity writing log files to the disk, so just spinning it down
when it's idle won't help much.
I'm looking for a recipe to buffer all the log files in RAM and
occasionally copy the updates back to the disk. (Say every few
hours. I have lots of RAM.)
Has anybody done this? Is there a good HOWTO on this, or close to this?
Is there a better approach? I can plug in a flash card if that helps.
If you have two or more computers on a LAN, why not have each machine keep its log files on the other?
