OK, i'll do that.

In fact, 1.0.1-1-mdk (Mandrake), you can find it on rpmfind.net

---------------
vgdisplay -h
Logical Volume Manager 1.0.1
Heinz Mauelshagen, Sistina Software  26/11/2001 (IOP 10)

vgdisplay -- display volume group information

vgdisplay [-c|--colon | -s|--short | -v[v]|--verbose [--verbose]]
         [-d|--debug] [-h|--help] [--version]
         [-A|--activevolumegroups | [-D|--disk] [VolumeGroupName...] ]

A little more info :

i tried to reimport the old PVs
----------------
]# vgimport -f -v main /dev/sda1 /dev/sda3
vgimport -- locking logical volume manager
vgimport -- checking volume group name
vgimport -- checking volume group "main" existence
vgimport -- trying to read physical volumes
vgimport -- checking for duplicate physical volumes
vgimport -- checking physical volume name "/dev/sda1"
vgimport -- reading data of physical volume "/dev/sda1" from disk
vgimport -- checking for exported physical volume "/dev/sda1"
vgimport -- reallocating memory
vgimport -- checking consistency of physical volume "/dev/sda1"
vgimport -- checking for duplicate physical volumes
vgimport -- checking physical volume name "/dev/sda3"
vgimport -- reading data of physical volume "/dev/sda3" from disk
vgimport -- checking for exported physical volume "/dev/sda3"
vgimport -- reallocating memory
vgimport -- checking consistency of physical volume "/dev/sda3"
vgimport -- physical volumes "/dev/sda3" and "/dev/sda1" are in 
different volume groups

----------------

Next, i said my pvdata was identical for /dev/sda1 and /dev/sda3, but i 
discover that was'nt true :
---------------
#]pvdata -P /dev/sda3
--- Physical volume ---
PV Name               /dev/sda3
VG Name               main
PV Size               1.39 GB / NOT usable 7.65 MB [LVM: 125.00 KB]
PV#                   2
PV Status             NOT available
Allocatable           yes
Cur LV                1
PE Size (KByte)       4096
Total PE              355
Free PE               99
Allocated PE          256
PV UUID               none
----------------
see that PVUUID ?

So i did try uuid_fixer, which finally give me a human readable error :
----------------
]# ./uuid_fixer /dev/sda1 /dev/sda3
/dev/sda3 - UUID corrupt
----------------
Damned.
So where do we go now ?
thanks,
