Yes, you should be able to do it either way. I have built 6+ drive arrays
from clean install before without any problem.
IIRC, the command should just be mdadm /dev/md0 -level=5 -raid-devices=4
/dev/sd[a-d]1
You can also add a switch to force all drives active but you must also add

RAID5 is one of the levels that can be added to after creation. I think you
should boot from the install CD and read the mdadm man page. It contains all
the information you need to do what you want. That said, when you try to
build the 4-drive array, do you get any errors reported? You may need to
Can you add a drive to an array after it has been built?
I know you can add a hot spare, or remove a drive and add another, but I did
not think you could increase N, where the size of the array is N-1 * size of
each drive. How is the raid going to know which is data and which is parity?
Of course

Sorry I can't help you with your RAID. I have a RAID 5 with 3
I'm not sure why it is failing to boot for you with 4 drives but you may
want to try completing the install with 3 drives and then add the fourth
drive to your array after a successful reboot.

I am successfully able to install Arch Linux with 3 drives in a RAID5
array on Arch Linux using:
mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/sda2 /dev/sdb2 /dev/sdc2
Now when I attempt the install with 4 physical disks and add the same
command above with just attaching /dev/sdd2 and c
