Good thinking, Batman - but it ain't that:

$ lsmod | grep dm
dm_crypt 15364 0
dm_mirror 24832 0
dm_mod 62660 2 dm_crypt,dm_mirror

Also, dmraid -tay returns:

$ sudo dmraid -tay
nvidia_acihdbbb: 0 976773166 mirror core 2 131072 nosync 2 /dev/sda 0 /dev/sdb 0

so the mirror is being detected ok, and dmraid -n returns:

$ sudo dmraid -n
/dev/sdb (nvidia):

However, dmraid -ay fails silently:

$ sudo dmraid -ay
$

but with the following in /var/log/messages:
