Well I assumed it wasn't you. Reloading 600 CDs must be very unpleasant
indeed. What I wonder is just how and why all the data was put on 600
CDs to begin with. That reminds me of my DJ days backing up my 40 mb
amiga HD to 40 or so floppies. ;-)

I'm using mdadm on linux. I decided against partitioning the raid since
it makes less sense and is not as straight forward as it is without a raid.

Currently it's only the mailstore and similar critical data which is put
on a raid. To keep it simple (and to actually upgrade the systems
involved without noticeable downtime) I opted to have the OS remain on a
single disk.
