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.
