Default Physical extent size in RHEL5, RHEL6 and RHEL7
Each physical volume is divided chunks of data, known as physical extents, these extents have the same size as the logical extents for the volume group.
Making the PE too small wouldn't be recommended, as the maximum volume size is 65,536 PEs, so if you reduce this to 1MB, you end up with volumes not larger than 64GB.
RHEL 5 - 32 M
RHEL 6 - 4 MB (maximum we can create 256 GB file system)
RHEL 7 - 4 MB
