Hello:
I know that a correct software mirror raid is subject to failures, when
anything wrong is written to both disks. And I also know that hardware

Francesco, you might want to keep a copy
I have no other machines than the said two servers. As soon as a machine

that it doesn't really matter. If you have RAID then you know you
