DESCRIPTION

13       thin_repair  reads binary thin provisioning metadata created by the re‐
14       spective device-mapper target from one device or file, repairs  it  and
15       writes it to different device or file. If written to a metadata device,
16       the metadata can be processed by the device-mapper target.
17
18       This tool cannot be run on live metadata.

50
51           $ thin_repair -i metadata -o /dev/vg/metadata
