First see if these will work ...
  mdadm hotadd /dev/md0 /dev/sdb1
  mdadm hotadd /dev/md1 /dev/sdb2

if not;

Looks like sdb is not functional.
try
  fdisk /dev/sdb
to see if the system can find it.
also you might look to see if boot found it.
  dmesg | grep sdb

If fdisk found it, you might try deleting the partitions
then do;
  mdadm /dev/md0 -a /dev/sdb1
  mdadm /dev/md0 -a /dev/sdb2
