pmempool-check - Man Page
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 pmemobj pool is limited to pool header consistency only and neither repair nor advanced options are 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.
