The following 3 lines in rc.sysinit for dmname in $(/sbin/dmraid -ay -i -p -t 2>/dev/null | \ egrep -iv "^no " | \ awk -F ':' '{ print $1 }') ; do Should be replaced with: for dmname in $(/sbin/dmraid -s -c -i); do Which besides being simpler also has the advantage of not listing subsets of layer raids (such as raid10) so that we do not try to activate individual subsets (which fails, and shows ugly error messages). Note the above lines were copy pasted from Fedora's rc.sysinit so the actual lines in RHEL might be slightly different, but the same principle applies. Also see bug 513169, which covers the mkinitrd counterpart of this (mkinitrd needs the same change for sets activated from the initrd).
This also requires the following upstream commit: http://git.fedorahosted.org/git/?p=initscripts.git;a=commitdiff;h=383fc9e4ed80c339339a91feeb3736ff637e84b8
