[linux-lvm] invalid lv in extent map

[Greg Freemyer]

I have recently upgraded a test server from 2.4.x with LVM 1 to 2.6.13
with LVM 2.

I can mount my 3 LVs, but when I try to do basic lvm commands I get
"invalid lv in extent map".

# pvscan
  invalid lv in extent map
  Couldn't fill logical volume maps.
  invalid lv in extent map
  Couldn't fill logical volume maps.
  No matching physical volumes found

# pvscan --version
  LVM version:     2.01.14 (2005-08-04)
  Library version: 1.01.04 (2005-08-02)
  Driver version:  4.4.0

I did not run vgconvert manually, so I assume I still have LVM1 metadata.

This is a test server, so none of the data in the LVs is important,
but I hope to be upgrading my live file server soon, so I would like
to figure out how to not lose any data.

Thanks
Greg
