# vdoaudit(8)

confirm the reference counts of a VDO device

## 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)](/lvmvdo/7.md).

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

## OPTIONS

- **--help**

- **--summary**

  Display a summary of any problems found on the volume.

- **--verbose**

  Display a line item for each inconsistency found on the volume.

- **--version**

  Show the version of vdoaudit.

# lvchange -ay vdo1/vdo0pool_vdata
