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
Print version information and exit.
-o {output file}
Write output to a file rather than stdout.
--metadata-snapshot
Use the metadata snapshot rather than the current superblock.
--written-since {era nr}
Blocks written since the given era will be listed.
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).
