You might be a candidate for LVM integrated raid. It uses the md kernel code on the backend, but it's all LVM tools to create, manage and monitor.

actually, I prefer zfs. I was just saying how I do it on CentOS, where zfs is not really an option.

# zpool create zbig mirror hd10 hd11 mirror hd12 hd13 mirror hd14 hd15 mirror hd16 hd17 mirror hd18 hd19 spare hd20 hd21 # zfs create -o mountpoint=/mystuff zbig/mystuff

done.

.... but, is that lvm integrated raid stuff available in RHEL/CentOS 6 or 7 yet ?
