[linux-lvm] LVM2 on-disk layout

["Tejas Sumant" <tejas sumant gmail com>]

I have few questions on lvm2 layout.

1) Why array of MDA (metadata area) is required? Isnt single MDA sufficient?
2) Which MDA is current?
3) Why the metadata inside MDA wraps around, instead of the offset
pointing to the start of metadata?

Can somebody kindly answers this?
