thin_check

THIN_CHECK(8)						      System Manager's Manual						     THIN_CHECK(8)

NAME

       thin_check - repair thin provisioning metadata on device or file

SYNOPSIS

       thin_check [options] {device|file}

DESCRIPTION

       thin_check checks thin provisioning metadata created by the device-mapper thin provisioning target on a device or file.

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.

       --skip-mappings
	      Skip checking of the block mappings which make up the bulk of the metadata.

       --ignore-non-fatal-errors
	      thin_check  will	only  return  a non-zero exit code if it finds a fatal error.  An example of a on fatal error is an incorrect data
	      block reference count causing a block to be considered allocated when it in fact isn't.  Ignoring errors for  a  long  time  is  not
	      advised, you really should be using thin_repair to fix them.

EXAMPLE

       Analyses and repairs thin provisioning metadata on logical volume /dev/vg/metadata:

       thin_check /dev/vg/metadata

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

DIAGNOSTICS

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