• LVM

Issue

• Error "Incorrect metadata area header checksum" comes on pvscan command:

Finding volume group "vgxorasapPRD"  
Fixing up missing size (34.04 GB) for PV /dev/emcpowere1  
Fixing up missing size (17.02 GB) for PV /dev/emcpowerl1

Resolution

• These errors come when the pv's are too large or missing/overwritten.

  Fixing up missing size (34.04 GB) for PV /dev/emcpowere1  
  Fixing up missing size (17.02 GB) for PV /dev/emcpowerl1
  

• Which is evident from the output of pvs

  • Incorrect metadata area header checksum

  Fixing up missing size (34.04 GB) for PV /dev/emcpowere1  
  Fixing up missing size (17.02 GB) for PV /dev/emcpowerl1
  

• Update the metadata by executing

[root@host ~]# vgchange -xn

• Then:

[root@host ~]# vgchange -xy

Root Cause

• The old metadata of lvm was causing the problem.  Updating the metadata fixed it.
