Hello, there,
I still need help regarding this topic. Do you need some more
information? Then please tell me.
In the meantime the system has been reinstalled, but a clone copy of the
old system exists. I am trying to rescue the old data. When working on
this I found a vgcfgbackup-file with valid-looking data. It begins with
---
# Generated by LVM2: <Date>
contents = "Text Format Volume Group"
version = 1
---
When trying "vgcfgrestore -f </above/described/file> volg1" on a Knoppix
5.0.1 with LVM version 2.02.05 (Details at the end of quoted posting) I get
PV /dev/hde2 is a different format (seqno lvm1)
Restore failed.
What can I do to get my data back?
Thanks
Paul

Hello everybody,
I have a really big problem: I cannot access my LVM1 PVs, VGs an LVs any more. So the system does not boot up.
The system was installed with Debian Woody and LVM1. I created 1 PV, 1 VG and some LVs. Later (maybe when changing to Sarge or Etch) I moved to LVM2, so I thought, I could remove the package lvm10 from the system. At some time I added another PV to the VG, resized one of the LVs.
Maybe because of one of this or when changing from Kernel 2.4 to 2.6.18 I obviously lost support for LVM1.
The last messages from the running system were:
# vgdisplay
Invalid LV in extent map (PV /dev/sda3, PE 1080, LV 5, LE 0)
Couldn't fill logical volume maps.
Invalid LV in extent map (PV /dev/sda3, PE 1080, LV 5, LE 0)
Couldn't fill logical volume maps.
Volume group "volg1" not found
As said before, after a reboot the system did not come up again telling me, it cannot find the LVs.
Please help me as I need the system and don't want to reinstall it. If you need some more information, please drop me a mail.
Maybe there is a live-CD with old LVM1-support available with which I could boot, activate the old LVM, chroot to it and reinstall the lvm10-Package? (I would need the module megaraid since the PVs are on an hardware-RAID.)
Thanks a lot in advance.
Paul
Some details:

There are two PVs, because some time the 36GB disk was replaced by a 7GB one.
