LVM partition(8e type) begins with a magic number(0x4D48) - HM,
At this sector, I get the name of volume group plus two three more structures, which I am unable to decipher. So, if anyone can let me know the details of these structures.

In my case, I had made two logical volumes in my LVM volume group. I want to know if I can get the start of these logical volumes from the sector where LVM begins. Suppose my LVM begins at sector 208845, then by adding 88 to it, I get 208933. At sector no. 208933, I get the information of both the logical volumes but not able to get the start of my logical volumes from this sector(i.e. sector no. 208933). Manually tracing it through WinHex, I can get the start of both the logical volumes but this information must be present at sector no. 208845(from where LVM begins which I get it from MBR) and at sector no. 208933 (208845 plus 88).

Now, if I extend first logical volume by some GBs within that volume group, then it keeps the extended copy after the second logical volume, but I am unable to make the connectivity between the extended and the prior one.
