These are a few of the commands I have ran so far...

cat /proc/mdstat
Personalities : [raid0] [raid1] [raid5] [raid6]
Md1 : active raid1 hdd1[2] hdc1[1] hda1[0]
        104320 blocks [3/3] [UUU]


(Just so you know... That's missing the "needed" MD2)

lvm pvscan
        - No matching physical volumes found
lvm lvscan
        - No volume groups found
lvm vgscan
        -  Reading all physical volumes.  This may take a while....
        No volume groups found

lvm vgchange -ay
        No volume groups found

lvm vgdisplay
        No volume groups found

fdisk -l /dev/hdd

 raidstart /dev/md1
        -       No errors, just returns command prompt
 
 raidstart /dev/md2
        -       No errors, just returns command prompt




Sooooooooo,  Then I tried to start fixing things.....

      mdadm --assemble -m 2 /dev/md2 /dev/hda2 /dev/hdc2 /dev/hdd2

I get
Mdadm: Bad super-minor number: /dev/md2

      mdadm --assemble --run -m 2 /dev/md2 /dev/hda2 /dev/hdc2 /dev/hdd2
 

Mdadm: failed to RUN_ARRAY /dev/md2: Invalid argument

Then... Looking at 

cat /proc/mdstat

Personalities : [raid0] [raid1] [raid5] [raid6]
Md1 : active raid1 hdd1[2] hdc1[1] hda1[0]
        104320 blocks [3/3] [UUU]

Md2 : inactive hdc2[1] hdd2[2]
        312367616
Unused devices: <none>


Then... Trying to get a little more pushy...

 mdadm --stop /dev/md2
 mdadm --verbose --assemble --run -m 2 /dev/md2 /dev/hda2 /dev/hdc2
/dev/hdd2

Mdadm: looking for devices for /dev/md2
Mdadm: /dev/hda2 is identified as a member of /dev/md2, slot 0
Mdadm: /dev/hdc2 is identified as a member of /dev/md2, slot 1
Mdadm: /dev/hdd2 is identified as a member of /dev/md2, slot 2
Mdadm: added /dev/hda2 to /dev/md2 as 0
Mdadm: added /dev/hdd2 to /dev/md2 as 2
Mdadm: added /dev/hdc2 to /dev/md2 as 1
Mdadm: failed to RUN_ARRAY /dev/md2: Invalid argument


Ok... So... That is where I quit...    Any Idea what kind of hope I should
be holding out for?
