NAME

       pmempool-check - check and repair persistent memory pool

SYNOPSIS

              $ pmempool check [<options>] <file>

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.
