I’ve been beating my head against this for the second day now, and think I’m going in circles now, so could use some external guidance please.
This is in a laptop with two hard drives running opensuse 11.1.
I setup raid1 (mirror) between the two drives.
md0 mounts root / using sda8 and sdb8
md1 mounts /home user sda9 and sdb9
/home is also encrypted (LUKS password at boot time).
And I (think) I added a second layer of encryption (but not sure at this point) encrypted the specific director /home/user.
This system has been purring along fine with this setup for months. All of a sudden on a boot up yesterday afternoon (it was working earlier on bootup that morning), I couldn’t access /home anymore. It didn’t ask for the LUKS password, and showed errors on the bootup indicating that the md1 was not a device, and so crypt couldn’t load.
md0 loads fine (root).
When the system boots or runs /etc/init.d/boot.crypt-early it fails because md1 fails (or the interdependency between them).
Here is some output, maybe folks can help point me in the right direction, I’ve tried dozens of sites and forums approaches from previous others postings, but not quite getting there.
Here some info:

Thanks for any suggestions.
What else can I provide? Does anything jump out at anyone as to what’s wrong?
I’ve run the BIOS’s HD test and checked smart and no errors on either drive there.
