Re: [linux-lvm] [Linux-lvm] Need help in understanding the logical to physical mapping by LVM

[Anuj Goel <talk2anuj gmail com>]

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 !!

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