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
