[linux-lvm] PV not reconized after vgcfgrestore?

[Rainer Hoerbe]

After my a system (lvm 1.0.6) hung, volume group data (out of 2) 
disappeard. There were no IO-errors in the system log.

A pvscan will not show the lost PV, and vgimport tells:
vgimport -- ERROR "pv_read(): PV identifier invalid" reading physical 
volume "/dev/hde1"

Now, when I try to restore, it should fix the PV in my understanding. 
But pvscan still does not bring it back. What could I do?

Your help is appreciated, as it would save me a day of work since the 
last backup :-)
