NAME<\/a> thin_dump<\/b> – dump thin provisioning metadata from device or file to standard output.<\/p>\n thin_dump<\/b> [options<\/i>] {device|file}<\/p>\n thin_dump<\/b> dumps binary thin provisioning metadata (optionally from alternate block; see option –metadata-snap<\/b>) created by the device-mapper thin provisioning target on a device or file to standard output for analysis or postprocessing in either XML or human readable format. XML formated metadata can be fed into thin_restore (see thin_restore<\/b>(8)) in order to put it back onto a metadata device (to process by the device-mapper target) or file.<\/p>\n This tool cannot be run on live metadata unless the –metadata-snap<\/b> option is used.<\/p>\n -h, –help<\/b><\/p>\n Print help and exit.<\/p>\n -V, –version<\/b><\/p>\n Print version information and exit.<\/p>\n -f, –format {xml|human_readable|custom}<\/b><\/p>\n Choose output format.<\/p>\n Custom formats are supported via shared library plugins. They should be $ thin_dump –format custom=mylib.so \/dev\/sda Repair the metadata whilst dumping it.<\/p>\n -m, –metadata-snap{= Dump metadata snapshot.<\/p>\n If block is not provided, access the default metadata snapshot created by Dump the specified device.<\/p>\n This option may be specified multiple times to select more than one thin Do not dump the mappings.<\/p>\n -o {xml file}<\/b><\/p>\n Specify a file for the output rather than writing to stdout.<\/p>\n Dumps the thin provisioning metadata on logical volume \/dev\/vg\/metadata to standard output in human readable format:<\/p>\n $ thin_dump -f human_readable \/dev\/vg\/metadata<\/p>\n Dumps the thin provisioning metadata on logical volume \/dev\/vg\/metadata to standard output in XML format:<\/p>\n $ thin_dump \/dev\/vg\/metadata<\/p>\n Dumps the thin provisioning metadata snapshot on logical volume \/dev\/vg\/metadata to standard output in human readable format (not processable by thin_restore<\/b>(8)):<\/p>\n $ thin_dump –format human_readable –metadata-snap \/dev\/vg\/metadata<\/p>\n thin_dump<\/b> returns an exit code of 0 for success or 1 for error.<\/p>\n
