Hello,
I know that it is possible to find where a given logical volume's extents
start on a PVs thanks to the information printed by lvdisplay --maps.
I was also able to experimentally establish that the actual data of an LV
starts one megabyte after that location. Is that offset documented
anywhere, or can I somehow discover it at runtime for a given LV?
regards,
Marcin
