My real suggestion to you is to now collect all the information you
can on the system, including drive serial numbers, and how they map to

reboots, or you add new disks, things get re-arranged and you don't
notice at first.  And that leads you down the wrong path quite
quickly.

Sylvain, a nice script for documenting device serial numbers,
partitions, RAID memberships etc can be found here:
