Physical Volume is using an old PV header

This document (000019878) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 15 SP2

Situation

When running the pvs command the following warning is displayed: 
 
s15sp2:~ # pvs -o +pv_ext_vsn
  WARNING: PV /dev/sde1 in VG vgdata01 is using an old PV header, modify the VG to update.
  PV         VG          Fmt  Attr PSize   PFree    PExtVsn
  /dev/sde1  vgdata01 lvm2 a--  200.00m       0        0

Resolution

To fix the issue, kindly use vgck command to update the PV metadata header to version 2. For example: 
 
s15sp2:~ # vgck --updatemetadata vgdata01
  WARNING: PV /dev/sde1 in VG vgdata01 is using an old PV header, modify the VG to update.
  WARNING: updating PV header on /dev/sde1 for VG vgdata01.

s15sp2:~ # pvs -o +pv_ext_vsn
  PV         VG          Fmt  Attr PSize   PFree    PExtVsn
  /dev/sde1  vgdata01 lvm2 a--  200.00m       0        2

After running vgck the PExtVsn changed from 0 to 2. 
Note: In above example the vgdata01 VG was migrated from SLES 11 SP4 to SLES 15 SP2.
In SLES 12 SP4|5 LVM uses LVM2 metadata. In older versions LVM1 can be used. 
 

Cause

This warning is caused by lvm metadata with old extension header version.
The related pv was created by old lvm2, and newer lvm2 will output the warning.
