NAME

       era_check - validate era metadata on device or file

SYNOPSIS

       era_check [options] {device|file}

DESCRIPTION

       era_check  checks  era metadata created by the device-mapper era target
       on a device or file.

       This tool cannot be run on live metadata.

OPTIONS

       -q, --quiet
              Suppress output messages, return only exit code.

       -h, --help
              Print help and exit.

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

       --super-block-only
              Only check the superblock is present.

              era_check will return a non-zero exit code if it finds  a  fatal
              error.  If any errors are discovered use era_repair to correct.

EXAMPLE

       Analyse thin provisioning metadata on logical volume /dev/vg/metadata:

       era_check /dev/vg/metadata

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

DIAGNOSTICS

       era_check returns an exit code of 0 for success or 1 for error.
