LVM partition (8e type) begins with a magic number (0x4D4 - 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 by getting their respective superblocks 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 8.

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
