I've scored everyone up as you've all helped in some way of getting me to where I needed to be. I'm filling out this answer for completeness should anyone else ever find themselves in the same bind.
My issues were several, so I'll try and outline them:
On the new box, I failed to (in no particular order):
- Have the appropriate file system
module available (ext4)
- Have the appropriate RAID kernel
modules available (RAID456)
- Mount the software RAID devices I
had created (mdadm --assemble
- Marked the filter in
/etc/lvm/lvm.conf to accept the md
device as a possible vggroup
After all that, the VG loaded fine and I am able to mount the LV that were created.
Now I just have to figure out a way to remove the miscellaneous md devices I created and merge it all into the VG... If that's possible. Expect another SuperUser question from me shortly. :)
