thin_rmap - output reverse map of a thin provisioned region of blocks from metadata device or file.
SYNOPSIS
thin_rmap [options] {device|file}
DESCRIPTION
thin_rmap outputs the reverse mapping stored in the metadata on a device or file between a region of thin provisioned pool blocks and the associated thin provisioned devices.
This tool cannot be run on live metadata.
