looks like the device is a raid level 1..

cat /etc/raidtab
raiddev             /dev/md0
raid-level                  1
nr-raid-disks               2
chunk-size                  64k
persistent-superblock       1
#nr-spare-disks     0
     device          /dev/hdd1
     raid-disk     0
     device          /dev/hdc1
     raid-disk     1

But still.. how I do I preserve the raid while upgrading the system?  
Ugh.  I'm tired, need sleep.
