Error in setup-storage in FAI 4.1

Hello,

I'd like to ask again if there has been any progress with getting
setup-storage to work with LVM again? Following my bug report (#740929)
from March, there has been a response but so far I found no solution
which works for me.

To summarize again: we need to be able to run setup-storage on a
previously installed machine with an existing LVM. We need to be able to
keep a LV of this LVM so we cannot just wipe everything out beforehand.

What I have tried so far:

Use liblinux-lvm-perl 0.16-2 (which includes a patch from Thomas Lange):
now setup-storage chokes on 'wipefs -a vg1/swap', which I think should
have read 'wipefs -a /dev/vg1/swap'.

Use liblinux-lvm-perl 0.17-1 (from the FAI repos, apparently with
Thomas' patch removed again):
gives the same 'Use of uninitialized value $lvn in hash element at
/usr/share/perl5/LVM.pm line 300.' which I described before.

Use liblinux-lvm-perl 0.17-1 with a patch from Roland Dieterich applied
(https://rt.cpan.org/Public/Bug/Display.html?id=94991):
Gives the wipefs bug again.

There are a number of reports around these problems, each referencing
one another, but I lost my way somewhere through this... Is there any
real solution for this?

Thanks,
Andreas
