Error description

  • chvg -g vgname may cause an error shown below:
0516-072 lqueryvg: Bad-block directory is corrupted. The
physical
        volume data has been permanently damaged. Run
diagnostics.

Local fix

  • 



Problem summary


    

  • For 4k block size VGs, chvg -g will fail, and cause future LVM
commands to fail with the error above about corrupt Bad-block
directory.
.
This is because chvg -g erroneously tries to set a bad block
sector during the grow disk operation, when 4k block size
VGs do not support bad block relocation

    



Problem conclusion


    

  • Correct chvg -g code to not try to update bad block directory
information for 4k block size VGs.

    



Temporary fix
