       era_invalidate [options] {device|file}


DESCRIPTION
       era_invalidate Examines era metadata and lists blocks that may have changed since a given era.

       This tool cannot be run on live metadata unless the --metadata-snap option is used.

              Print help and exit.

       -V, --version
              Output version information and exit.

       -o <output file>
              Write output to a file rather than stdout


EXAMPLE
       List  the  blocks  that  may  have  been  written  since  the  beginning of era 13 on the metadata device
       /dev/vg/metadata.

       era_invalidate --written-since 13 /dev/vg/metadata

       The device may not be actively used by the target when running.


DIAGNOSTICS
