[linux-lvm] only found 0 of 5120 LEs for LV

[Nay, Shawn]

Well the pvdata -E output for my drives was empty, no LV's listed.

This is kind of disappointing.  I have been using LVM under AIX for some
time and am familiar with the concepts and it's not that complicated.  I
have been able to import, export, and manipulate disks as I please under the
linux.  Once I rebuild my OS though, using the same version of LVM and its
tools, I am out of luck performing an import.  The only thing that I am not
doing that I should be is performing a proper export before the rebuild.  I
have been using vgimport -f to force the import of my VG.  

I have not seen any posts in regards to this same problem which would lead
me to believe that it is something that I am doing wrong.  Am I just missing
a step that is obvious to everyone else?  Is there something that I need to
manually do in /etc concerning my disks and LVM?

Thanks for the help,
Shawn

Send the output of "pvdata -E /dev/whatever" for all the PVs, and we can
see if your LV even exists anymore.  If it is overwritten, I'm wondering
if this is the same bug as hit Lars.  Maybe related to the recent change
to zero out unused parts of the VGDA.

Cheers, Andreas
