[linux-lvm] Missing PV

I have encountered a situation where vgscan and vgchange are complaining
about a missing UUID.
As far as I know, all, or almost all, of the LV is on the PV that is
known ( how do I know for sure? ), so I think that I am trying to just
"remove" the PV and recover what I can of the LV.
I have read Milan Brosz' slides from 2009, and the only piece that I
seem to be missing is the recovery of the LV.
I have made a copy of the PV to work with and the procedure that I need
to follow, as I understand it, is as follows:
vgscan
vgchange -a y ( fails )
vgchange -a y --partial
vgreduce --removemissing vgname
then what?
I have done:
pvs -o +uuid
lvs -o +devices
But am not sure how to interpret the results. lvs shows two entries for
the LV that I am interested in. The second entry shows "unknown device(0)".
Thank you,
Brian
