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 then, vgscan -vvv said ( also edited ):

.

And nothing more about the supposed VGs on those partitions.


What should I try next?


Thanks,
Brian

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?
