I'm a new to lvm and confused about as titled.
What's the difference between
thin_ll_restore & thin_restore
thin_ll_dump & thin_dump?
Thanks

thin_ll_* tools are targeted for recovering missing data mappings
ignored by thin_dump and thin_restore. The name is an acronym standing
for low-level processing. Below is the quickstart guide.

The page doesn't describe detail about thin_ll_* tools.
After I run it, get some observations.
thin_ll_dump seems dump the tree root & mapping tree and orphans
blocknr.(seems having orphans is normal)
And that info is which thin_dump doesn't get it.
