```

# [DESCRIPTION](#DESCRIPTION)

**thin\_repair** reads binary thin provisioning metadata created by the respective device-mapper target from one device or file, repairs it and writes it to different device or file. If written to a metadata device, the metadata can be processed by the device-mapper target.
