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 ):

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

Am I understanding that "pvcreate" was executed on these two partitions,
but not "vgcreate" or "lvcreate".
Thanks,

A few days ago, I asked about an old drive that I have that has two
partitions, typed as "fd" ( Linux RAID autodetect ). Running vgscan and
pvscan doesn't seem to produce anything that makes sense to me, because
I expect to see VGs on these two partitions.
I then went on to "pvdisplay" and see the following, which seems to say
that the "pvcreate" command was run on both partitions, but that nothing
else was done. Am I correct, and am I dealing with two basically unused
LVM2 partitions?
