[linux-lvm] Help: lvm 0.9.1_beta3 oops (desperate plea)

[Joe Harvell]

I really, really, really need the data that is on this VG.

So if anyone at Sistina really wants to get to the bottom of this, you just got yourself a dedicated beta-tester.  I am an experienced software developper with a small amount of Linux device-driver experience.  I can provide hexdumps of the relevant portions of the actual partitions.  I am willing to run any series of tests on this machine to help find the root cause of this problem.  Whatever it takes.

Not only do I want to recover the data, I really want to use LVM.  In order to do that, I have to be able to trust it.  So that's why I want to find the root cause.

Not that I'm from Sistina, but one thing you could start out checking is
in lvm_read_all_pv_of_vg(), and print out the PV list at each step of the
way.  It may be possible that some of the PVs are being removed from the
list, even though they are not supposed to.  The first list, returned
from lvm_read_all_pv(), should be all of the PVs on your system.

Cheers, Andreas

Andreas has a good point here.

Minor correction: the names of the functions are pv_read_all_pv()
and pv_read_all_pv_of_vg().
