Hello, This is my second e-mail.
Where does the mapping between PE and LE is done? And When happen?
When the new Logical Volume is created based on already built PV and VG,
is the mapping done?
In the source code, /lib/metadata/metadata.h, there are "lv_segment"
& "pv_segment". does the "segment" equal the "extent"??
Each "physical_volume" struct and "logical_volume" struct has a segment list
like "pv_segment" and "lv_segment". But there are also "pv_list" and "lv_list".
How the mapping is done with these structures..??
One more thing is, "What code do I have to read in the sources to know
how the mapping is done??"
Thank you ^^:
