I was able to use thin_ls and it nicely dumped the aggregate level statistics for each block. Will it be possible to dump the individual blocks themselves with similar headings. Like: LIST_MAPPED_BLOCKS LIST_EXCLUSIVE_BLOCKS LIST_SHARED_BLOCKS The tool thin_dump dumps the individual blocks but does not provide the information if they are shared or exclusive. One could write a tool on top of thin_dump to parse the information but it is not that simple especially if there are huge no of entries. Thank you once again for the tool.
