SYNOPSISthin_repair [options] -i {device|file} -o {device|file}
DESCRIPTIONthin_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.
This tool cannot be run on live metadata.

-V, --version
Print version information and exit.
-i, --input {device|file}
Input file or device with binary data.
-o, --output {device|file}

If a file is used for output, then it must be preallocated, and large
enough to hold the metadata.
EXAMPLE

it and writes it to logical volume /dev/vg/metadata for further pro‐
cessing by the respective device-mapper target:
$ thin_repair-i metadata -o /dev/vg/metadata
