when ever I try creating a RAID setup with the disck utility it gives me the following error:
Error creating RAID array: Error spawning command-line `mdadm --create /dev/md127 --run --chunk 512 --level raid6 --name "storage" --raid-devices 4 "/dev/sda" "/dev/sdc" "/dev/sdd" "/dev/sdf"': Failed to execute child process "mdadm" (No such file or directory) (g-exec-error-quark, 8) (udisks-error-quark, 0)
It appears that I am missing the mdadm library
