Is there a way, I can figure out the base physical device, that I am residing on. For example say, physical devices, which cannot be removed/edited/modified....

If I understand your question correctly, lvdisplay --maps does what you're looking for. It reports where each part of a logical volume resides.

  • You mean like, how LVM chooses which physical volumes to use for allocating space to an LV and how it breaks the LV into multiple mappings? I don't know of any references because I don't really know or care how it does it. For me it just does its job well. – Celada Jun 19 '12 at 14:16
