NAME
thin_repair - repair thin provisioning binary metadata.
SYNOPSIS
thin_repair [options] -i {device|file} -o {device|file}
DESCRIPTION
thin_repair reads binary thin provisioning metadata created by the re-
spective 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

-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.

--data-block-size {natural}
Override the data block size given in the input xml.
--nr-data-blocks {natural}

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