Yes, md0 is over sda1 and sdb1:

danp at cream:~$ cat /proc/mdstat 
Personalities : [raid1] 
md2 : active raid1 sdb3[1] sda3[0]
      241207872 blocks [2/2] [UU]
      
md1 : active (auto-read-only) raid1 sda2[0] sdb2[1]
      1951808 blocks [2/2] [UU]
      
md0 : active raid1 sda1[0] sdb1[1]
      979840 blocks [2/2] [UU]

Just in response to this - my problem has not been caused by an upgrade - it was a clean lenny install
onto a new machine a few days ago.
