[linux-lvm] no volume groups found

[Ulrich Wiederhold <U.Wiederhold@gmx.net>]

Hello,
I use 2.4.9 with debian unstable and lvm version 0.9.1_beta6. I don´t
use devfs and compiled lvm into the kernel.
I created a vg nameed vg01 containing hda2,hdb1,hdd1,sdb1 and sdc1. Then
I created some lv´s and made a mkfs.xfs.
I could do a "vgscan -v && vgchange -a y" and mount my lv´s.

After a reboot, /etc/rcS.d/S25lvm couldn´t find any vg´s. So I ran the
script manually and it works.

I had some other problems that need me to reboot and my PC crashed several
times. Now, I can´t even run the script manually. I always get this:

home:# vgscan -v
vgscan -- removing "/etc/lvmtab" and "/etc/lvmtab.d"
vgscan -- creating empty "/etc/lvmtab" and "/etc/lvmtab.d"
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group

home:# vgchange -a y
vgchange -- no volume groups found

home:# vgdisplay
vgdisplay -- no volume groups found

Then I did "man vgcfgrestore" and tryed
home:# vgcfgrestore -n vg01 -l
vgcfgrestore -- ERROR: different structure size stored in
"/etc/lvmconf/vg01.conf" than expected in file vg_cfgrestore.c [line
137]
vgcfgrestore -- ERROR "vg_cfgrestore(): read" restoring volume group
"vg01"

and:
home:# vgcfgrestore -f /etc/lvmconf/vg01.conf.1.old -n vg01 /dev/sdb1
vgcfgrestore -- ERROR: different structure size stored in
"/etc/lvmconf/vg01.conf.1.old" than expected in file vg_cfgrestore.c
[line 137]
vgcfgrestore -- ERROR "vg_cfgrestore(): read" restoring volume group
"vg01"

What "PhysicalVolumePath" should I use with it?

Then I looked in the mail-archive and did a:

So, what else can I do?
I don´t want lose my data!

Any hints?
