Since my LVM partition has been moved by the operations on the
partitions with fdisk. I had to use the vgcfgrestore command as follow
and getting the following error:

[root at einstein sbin]# vgcfgrestore -n datavg -o /dev/sda9 /dev/sda7
vgcfgrestore -- INFO: using backup file "/etc/lvmconf/datavg.conf"
vgcfgrestore -- ERROR "pv_read(): PV identifier invalid" reading physical volume "/dev/sda7"

Is there still something I can try or should I forget it?
