[linux-lvm] Lost free PV -> error reading VG



Hi Folks!

I had a vg "debian" with the pvs /dev/hda2 /dev/hda3 /dev/hda4
I wanted to remove /dev/hda4, so i did:  pvmove -v /dev/hda4 
Everything went well, so I removed /dev/hda4, but _without_ the use of:
vgreduce debian /dev/hda4 :-( 
I also did: pvcreate /dev/hda4 , so /dev/hda4 seems to be an empty pv, and
it does not know that it belongs
to the vg "debian".

And now, I get:

root ttyp0[root]# vgscan 
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of
volume group "debian" from physical volume(s)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group

root ttyp0[root]# pvscan 
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/hda2"  is associated to unknown VG "debian" (run
vgscan)
pvscan -- inactive PV "/dev/hda3"  is associated to unknown VG "debian" (run
vgscan)
pvscan -- inactive PV "/dev/hda4" is in no VG  [23.85 GB]
pvscan -- total: 3 [57.24 GB] / in use: 2 [33.38 GB] / in no VG: 1 [23.85
GB]

How can I recover my vg? There are no backups :-(
How can I tell the vg "debian" to do not use: the empty pv /dev/hda4?
Or, how can I tell /dev/hda4 that it belongs to the vg "debian"?
There is no lvmconf too :-(

What additional information do you need to be able to help me?

Thanks
 Stefan
