Installer does not have raid10 as an option. Not sure whether boot cd
has this module or not. But after installing, it exists.

Current mdadm raid10 version in CentOS5 is a little old (v2.5.4 - 13
October 2006) and has a bug which sometimes kicks one drive from raid
after initial resync and repeats kicking-after-resync when hot added
again and again and again.
