Sets the physical extent size on physical volumes of this volume
group. A size suffix (k for kilobytes up to t for terabytes) is
optional, megabytes is the default if no suffix is present.
Values can be from 8 KB to 16 GB in powers of 2. The default of
4 MB causes maximum LV sizes of ~256GB because as many as ~64k
extents are supported per LV. In case larger maximum LV sizes
are needed (later), you need to set the PE size to a larger
value as well. Later changes of the PE size in an existing VG
are not supported.
So it seems you have a 255 GiB limit on LV sizes with your LVM2 setup. This
same limitation is what applies to LVM2 Logical Volumes, and the math is
simple to do.
