2012-03-06 00:04:55 +05:30
.B thin_dump
dumps binary thin provisioning metadata (optionally from alternate block;

thin provisioning target on a device or file to standard output for

analysis or postprocessing in either XML or human readable format.
2011-12-15 18:26:48 +05:30
XML formated metadata can be fed into thin_restore (see
2012-03-06 00:04:55 +05:30
.BR thin_restore(8) )
in order to put it back onto a metadata device (to process by
2011-12-15 18:26:48 +05:30
the device-mapper target) or file.
