thin_repair ā€” 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 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.

Options

-h, --help

Print help and exit.

-V, --version

Print version information and exit.

-i, --input {device|file}

Input file or device with binary data.

-o, --output {device|file}

Output file or device for binary data.

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

Example

Reads the binary thin provisioning metadata from file metadata, repairs it and writes it to logical volume /dev/vg/metadata for further processing by the respective device-mapper target:

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

Diagnostics

thin_repair returns an exit code of 0 for success or 1 for error.
