Ah, finally I find some real information in the log!  Thanks for your
patience.

The label wasn't found.  I guess that's a good enough reason to not
find the vg.

The second log continues to find the lvs and works there.


Any ideas as to why it doesn't find the lvm label with kernel 2.6?
What should I do to try correcting it?

TIA,
