SYNOPSIS

9       thin_repair [options] -i {device|file} -o {device|file}
10

DESCRIPTION

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

46       Reads the binary thin provisioning metadata from file metadata, repairs

48       cessing by the respective device-mapper target:
49
50           $ thin_repair -i metadata -o /dev/vg/metadata
