Yast is more or less a interface for the LVM tools, it is just for
people (like me) who are too lazy too look up the correct parameters.

As far as I understand vgcfgrestore, it is only useful if you have a
lvmtab resp. lvmtab.d which I do not have :-(

Thanks for the information I wasn't sure if LVM can kill my data
(forever) if I exectute commands like vgcreate etc.
Unfortunately this doesn't help me since somehow the VG is there
and somehow it isn't:
root@feynman:~ # vgcreate system2 /dev/hda6 /dev/hda7 /dev/hdb2
/dev/hdb5 /dev/hdb6 /dev/hdb7 [13:47]
vgcreate -- volume group directory or file already exists
vgcreate -- please choose a different name
Also reducing the number of PV does not help, probably since every
PV contains still the information that it belongs to "system2". Also
changing the VG name does not help...
root@feynman:~ # vgcreate system /dev/hda6 /dev/hda7 /dev/hdb2
/dev/hdb5 /dev/hdb6 /dev/hdb7 [13:47]
vgcreate -- "/dev/hda6" is not a new physical volume
vgcreate -- physical volume "/dev/hda6" already belongs to volume
group "system2"
On the other hand "system2" does not "exist"...
root@feynman:~ # vgchange -a y system2
[13:47]
vgchange -- volume group "system2" does not exist
root@feynman:~ # lvcreate -L1000 -ntestlv system2
[13:54]
lvcreate -- can't create logical volume: volume group "system2"
doesn't exist
Mmh, seems I can't execute any standard operations on these PVs.
Perhaps one of the authors of the program could be so kind and tell
me if there is any chance to get my data (at least partially) back?
Happy Easter,
Marco
