Also, I see sda2 listed as LVM although I didn't partition it that way. e.g. fdisk shows it as Linux type and pvscan is showing it as lvm2. That's somewhat confusing me. Also, the real problem for me is recovery. I don't see LVM mounted after doing vgscan and lvscan. Am I missing something here? Any help?
