[linux-lvm] Lost one disk from VG

[pfeffer2 at gmx.de]

Hello,

I've got a big problem. I lost one disk of my vg. The VG spans over 
hda4, hdb1 and hdd1. I use Logical Volume Manager 0.9.1_beta7.
I've replaced it with the same disk and tried to do a vgcfgrestore -vv -n 
vg00 -o /dev/hdd1 /dev/hdc1 but ist says:

vgcfgrestore -- locking logical volume manager
vgcfgrestore -- restoring volume group "vg00" from 
"/etc/lvmconf/vg00.conf"
vgcfgrestore -- checking existence of "/etc/lvmconf/vg00.conf"
vgcfgrestore -- reading volume group data for "vg00" from 
"/etc/lvmconf/vg00.conf"
vgcfgrestore -- reading physical volume data for "vg00" from 
"/etc/lvmconf/vg00.conf"
vgcfgrestore -- reading logical volume data for "vg00" from 
"/etc/lvmconf/vg00.conf"
vgcfgrestore -- checking volume group consistency of "vg00"
vgcfgrestore -- checking volume group consistency of "vg00"
vgcfgrestore -- reading physical volume "/dev/hdc1"
vgcfgrestore -- checking for new physical volume "/dev/hdc1"
vgcfgrestore -- size of physical volume /dev/hdc1 differs from backup

The next thing that makes me woder ist the output of pvdata -PP:

Should the system_id not be the same? How could I change the 
system_id?

vgscan dosen't find any volume groups.

How can I get the data from hda4 and hdb1?

Best regards
