Hey all,
I got it to work ONCE, but for the life of me I can't figure out how
to do it again.
This is what I think I did the first time, but for the second time it
just doesn't work.

---Now I'm stuck. All LVM instructions I find on the Internet say that
I find the path of the LVM device by using lvdisplay. Also I know that
one hour ago I had my volumes mounted and was copying data from them.
After properly syncing and unmounting them, and stopping the LVM and
md thingys, I'm stuck now.
Any suggestions?

I have a problem to understand what is actually your issue with LVM. Was
your system working before and now logical volumes that were existing
before disappeared?
What is the situation with volume group or groups? What does vgscan or
vgs commands say?
BR,
Roland
