list the devices associated with logical volumes under without using lvm2 package commands

Question

I want to list all the physical volume associated with logical volume.

I know lvdisplay, pvscan ,pvdisplay -m could do the job .but I dont want to use this command. Is there any other way to do it without using lvm2 package commands?

Any thoughts on comparing Major and Minor number of device?

Answer 1

What about system-config-lvm:

Answer 2

If you know the Volume Group (possibly depending on your distro, it works for me under Ubuntu 12.04) you can discern the LV's by looking in /dev/mapper the block devices are all there, using a "-" to seperate the VG from the LV. I suspect this is an imperfect solution if, for example, you have other devices - I have 1 other virtual device, but its obvious which one it is, both by the name and because it doesn't have a "-"
