[linux-lvm] LVM2 robustness w/ large (>100TB) name spaces?

 From the LVM2 point of view, extents (PEs/LEs) are counted using 32-bit
numbers so that's where the limit comes from.
(You can change extent size later, shuffling extent boundaries with pvmove
first as necessary.)

The stripe size is controlled by a separate parameter essentially independent
of the PE size.

When creating the PVs, use a larger-than-default size for the metadata area:
it is awkward to change later if you fill it up.
