I think since inception of LVM2, type mirror has been available which
is now legacy (but still available). The current type since CentOS 6.3
is raid1. But yes for anything raid4+ you previously had to create it
with mdadm or use hardware RAID (which of course you can still do,
most people still prefer managing software raid with mdadm than lvm's
tools).
