Hi guys,
I want to understand how LVM maps a logical address to physical address.
I have downloaded the LVM code, but cannot figure out which files to look
into.

Can you please give some suggestions.

Look in /etc/lvm/backup/* to see the actual map.

Hi Ray,

I see that the /etc/lvm/backup has only one file which gives some basic
information about the physical volumes and logical volumes.

I am looking for some hints on where to look in the LVM code if I want to
see the entire sequence of address translation from a logical address given
by the application to the physical address on the underlying RAID5..
Any pointers to a document or paper explaining this would also be
appreciated !!
