NAME

       era_invalidate  -  Provide  a  list of blocks that have changed since a
       particular era.

SYNOPSIS

       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.

OPTIONS

       -h, --help
              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

       era_invalidate  returns  an  exit  code of 0 for success or 1 for error
       (eg, metadata corruption).
