If you can provide that piece of information, people will be able to help you better. ~David The situation (as I think it is) is that mail server is on a hardware RAID system formatted with LVM, but, the question I've been sent to answer is whether it's possible to connect that hardware RAID sub-system to another hardware RAID sub-system, using a _software_ RAID 1 (mirror), and have that software RAID be stable enough to allow the two systems to to function, _while_ the mail server is...uuhhh...serving mail :). Soooo... Old Mail server (Hardware RAID w/LVM) ==> Software RAID 1 mirror == > New Mail Server (empty hardware RAID) What is wanted is to take the mail server offline long enough to set up the software mirror, but, put it back online while the copying/synching is going on, so that we don't lose server access during that time.
