Great to know this because i have never seen this ever. But i want to know one thing that when i studied this, found that we keep this size bigger because of metadata. And if it is correct metadata will increase with the size of PV and VG then how can a specific formula be derived.
The PV and VG are irrelevant here, the goal is to find out how much logical ext3fs capacity we get from a raw block device of a certain size. When creating an LV we get a block device, ext3fs doesn't care whether it's an LV or a raw disk partition.
Note that lvextend increases only the _unformatted_ capacity. So if you extend by 2G, the useful capacity you get for new files on the ext3 filesystem on that volume is approximately 1.58% less than 2G due to ext3fs overhead.
