RAID 4 and 5 require three disks to actually work, so with only two disks they usually fall back to RAID 1, hence the warning.

What different behavior do you expect? Does using commandline storaged not throw a warning?

Sorry for the wrong input.I saw this when I was trying to reproduce a raid 1 bug,and I'm going to close the bug now.Maybe it's better to warn users when 
they try to create raid 5, raid 4 with two disks,like cockpit dose now for raid 6.
