In order for the information\nto be meaningful, you need to ensure the thin volumes you're examining are\nnot changing (ie, do not activate those thins).\n\n#### --verbose\n\nProvide extra information on the mappings.\n\n#### -h, --help\n\nPrint help and exit.\n\n#### -V, --version\n\nOutput version information and exit.\n\n### SEE ALSO\n\nthindump(8), thinrepair(8), thinrestore(8), thinrmap(8), thinmetadatasize(8)\n\n### AUTHOR\n\nJoe Thornber <ejt@redhat.com>, Heinz Mauelshagen <heinzm@redhat.com>\n\n\n\nSystem Manager's Manual                  Device Mapper Tools                           thindelta(8)\n\n"
