Read Raid Setup, the only thing you will need outside system is: "Patience, Pizza, and your favorite caffeinated beverage.". Arch Wiki article about Sofware RAID and LVM.
Basic idea behind RAID is to deal with independent disks as an array of drives. Raid 0 uses two or more disks as one, with performance gains without fault-tolerance. From raid 1 to 6 they offer diferent fault tolerance mechanisms.
LVM or Logic Volume Manager bring one more layer, read Lvm made easy. Partitions under lvm are easy to be resized, moved and there is a tool to help encrypt. There is more freedom to name physical disk names exp; production, development, backups...
Until now "from install" there is only one partition, it is good idea to have a system with diferent partitions for each propos. If is a "fresh install";
# cd /iso/crux/opt/
# pkgadd lvm2#2.02.107-1.pkg.tar.xz
#
Create a LVM partition, fdisk should show something like this;
# fdisk /dev/sdb
Welcome to fdisk (util-linux 2.26.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

You can move home directory to new one with just one command; "usermod -m -d /home/new user".
# mount /var/ports/distfiles
# mount /var/ports/packages
# umount /home/pkgmk/work
# mount /var/ports/work
# mv /home/pkgmk/distfiles/* /var/ports/distfiles/
# mv /home/pkgmk/packages/* /var/ports/packages/
# rm -R /home/pkgmk
# usermod -d /var/ports pkgmk
Check ownership, you may need recursive if partition has bin used on another system.
# chown pkgmk:pkgmk /var/ports/distfiles
# chown pkgmk:pkgmk /var/ports/packages
#
# mkdir /home/tmp
# mount /dev/homevg/homelv /home/tmp
