debian testing and mdadm

[Adam Olsen <adamo@mindzion.com>]

Hello,

I just recently attempted to use this method: 
http://synic.ath.cx/raid1.txt to create full software raid 1 on our 
server running debian testing.  I replaced all the references to 
raidtools with mdadm.

It seems to be working, cat /proc/mdstat shows:

Personalities : [raid1]
md2 : active raid1 sda2[1] sdb2[0]
      155308288 blocks [2/2] [UU]

unused devices: <none>

However, when I reboot, sda2 does not come up - I have to mdadm -a 
/dev/md2 /dev/sda2 to get it to come up.  It has to rebuild, which takes 
about an hour.

My /etc/mdadm/mdadm.conf looks like this:

DEVICE /dev/sda2,/dev/sdb2
ARRAY /dev/md2 level=raid1 num-devices=2 devices=/dev/sda1,/dev/sda2

How can I get /dev/sda2 to come up automatically?
