My apologies if this is not the right place to ask this question. 
Hopefully it is.

I created a RAID5 array with:

mdadm --create /dev/md0 --level=5 --raid-devices=5 /dev/sda1 /dev/sdb1 
/dev/sdc1 /dev/sdd1 /dev/sde1

mdadm -D /dev/md0 verifies the devices has a persistent super-block, but 
upon reboot, /dev/md0 does not get automatically assembled (an hence is 
not a installable/bootable device).

I have created several raid1 arrays and one raid5 array this way and 
have never had this problem.  In all fairness, this is the first time I 
have used mdadm for the job.  Usually, I boot to something like 
SysRescueCD, used raidtools to create my array and then reboot with my 
Slackware install CD.

Anyone know why this might be happening?
