Encryption enables me to RMA/sell/give away disks with reasonable expectation that the data on them won't be read. Since we're tight on space the server isn't as physically secure as I'd like. I doubt anyone could walk off with it without my knowledge, but rebooting into a root shell would be possible. > Well, you can always use your backup procedure to move the data off and put it back on under new encryption.

To be honest, I couldn't quite parse that one, but the gist of it seems to be positive. I'll leave the box as-is for the moment and see if I can't do something about that performance problem first, lest I have to redo the whole thing twice.
