Re: [linux-lvm] LVM2 release 2.02.03 / device-mapper 1.02.04



I just wanted to add that I am seeing this issue as well.  2.02.03 and
2.02.04 both seem to suffer the same problem.  Downgrading to 2.02.02
  seems to fix this issue.

   vgscan --version
     LVM version:     2.02.02 (2006-02-07)
	  Library version: 1.02.05 (2006-04-19)
	  Driver version:  4.4.0
  vgscan
  Reading all physical volumes.  This may take a while...
    Found volume group "vg01" using metadata type lvm2
      Found volume group "vg02" using metadata type lvm2



 with 2.02.03 or 2.02.04 I get this
 vgscan
   Reading all physical volumes.  This may take a while...
     WARNING: Duplicate VG name vg01: Existing

I have not rebooted between these upgrades I am not sure if that would
matter.  However, it appears that there are other people who have seen
this issue as well as noted in gentoo's bug reports and forums system.
