# pmempool-check(1)

check and repair persistent memory pool

## NAME

**pmempool-check** - check and repair persistent memory pool

## SYNOPSIS

-

  ```
  $ pmempool check [<options>] <file>
  ```

## NOTE

NOTICE: The **libpmemblk** and **libpmemlog** libraries are deprecated since PMDK 1.13.0 release.

## DESCRIPTION

The **pmempool** invoked with *check* command checks consistency of a given pool file. If the pool file is consistent **pmempool** exits with 0 value. If the pool file is not consistent non-zero error code is returned.

In case of any errors, the proper message is printed. The verbosity level may be increased using **-v** option. The output messages may be also suppressed using **-q** option.

It is possible to try to fix encountered problems using **-r** option. In order to be sure this will not corrupt your data you can either create backup of the pool file using **-b** option or just print what would be fixed without modifying original pool using **-N** option.

NOTE: Currently, checking the consistency of a *pmemobj* pool is **not** supported.

### Available options:

`-r, --repair`

Try to repair a pool file if possible.

`-y, --yes`

Answer yes on all questions.

`-d, --dry-run`

Don’t execute, just show what would be done. Not supported on Device DAX.

`-N, --no-exec`

Deprecated alias for `dry-run`.

`-b, --backup <file>`

Create backup of a pool file before executing. Terminate if it is *not* possible to create a backup file. This option requires **-r** option.

`-a, --advanced`

Perform advanced repairs. This option enables more aggressive steps in attempts to repair a pool. This option requires `-r, --repair`.

`-q, --quiet`

Be quiet and don’t print any messages.

`-v, --verbose`

Be more verbose.

`-h, --help`

Display help message and exit.

## EXAMPLE

-

  ```
  $ pmempool check pool.bin
  ```

-

  ```
  $ pmempool check --repair --backup pool.bin.backup pool.bin
  ```

Check consistency of “pool.bin” pool file, create backup and repair if necessary.

-

  ```
  $ pmempool check -rvN pool.bin
  ```

Check consistency of “pool.bin” pool file, print what would be repaired with increased verbosity level.
