Folks,
I have a drive with two "Linux raid autodetect" partitions, which, as
far as I know, have LVM VGs on them.
However, even though mdadm happily starts both RAID devices ( each half
of a RAID-1 device ), vgscan and pvscan don't give me answers that I
really understand.
First pvscan -vvv ( edited output ):
Processing: pvscan -vvv

And nothing more about the supposed VGs on those partitions.
What should I try next?
Thanks,
