I had this before and what I dit was reformat and recreate the lvm
because the vgchange -ay dit nor work with me also
If thare is no data on this disk this is the a way

with "vgchange -ay" will an rescan be executed

But I suggest that you read carefully the man because I don't now what
Will happen when thare is an problem

I used vgchange -ay in the past without problems but I don't guarantee
(because of production)

You will best wait for an second opinion because I'm not that specialist
but here was my experience (of last week)
(My OS was fedora5)
