I think that the --device-id option is required for thin_dump, but the necessity of --skip-mappings could be discussed. If thin_ls supports --device-id, then thin_dump might not require --skip-mappings. I put my code here for reference (based on v0.7-devel) https://github.com/mingnus/thin-provisioning-tools/commits/v0.7-thin_dump-enhancement I borrow the option name "--skip-mappings" and function name "set_skip_mappings" from Eric, since that they sounds more clear. Build method: # autoconf; ./configure --enable-dev-tools; make My use cases: # thin_dump --device-id=<dev_id> --format=<f> [--skip-mappings] Ming-Hung Tsai -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
