NAME

       vdoaudit - confirm the reference counts of a VDO device

SYNOPSIS

       vdoaudit [options...]  filename

DESCRIPTION

       vdoaudit  adds  up the logical block references to all physical blocks of a VDO device found in filename,
       then compares that sum to the stored number of logical  blocks.  It  also  confirms  all  of  the  actual
       reference  counts  on all physical blocks against the stored reference counts. Finally, it validates that
       the slab summary approximation of the free blocks in each slab is correct.

       filename must be the path of the VDODataLV as described in lvmvdo(7).

       If --verbose is specified, a line item will be reported for each inconsistency; otherwise  a  summary  of
       the problems will be displayed.

OPTIONS

       --verbose
