pmempool-check — check and repair persistent memory pool
$ pmempool check [<options>] <file>
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.
