Thats what I'm seeing right now.

Now, the old entry of sdb1 is still in the md0, but with state removed. 

(output of mdadm -D /dev/md0)

    Number   Major   Minor   RaidDevice State
       0       8        1        0      active sync   /dev/sda1
       1       0        0        -      removed

       2       8       17        1      spare rebuilding   /dev/sdb1


Is that OK?
