Using info from the following links,

Are you aware that using 2 disks on the same controller is generally
regarded as a "bad thing"[tm]?

I had personally lost access to a 2nd drive when one drive on the same bit
of cable failed. Fortunately in my case, I didn't lose data on the good
drive, but I wasunable to access it until I powered the PC down and
removed the failed drive.

Looks like you forgot to mkfs the new md0 device..

However, I've never used mdadm, prefering the old /etc/raditab method so
don't know if your mdadm command will preserve/extend the reiserfs
(although personally I think this is unlikely)
