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 changing the # of devices from 3 to 4, I get a failure. When I reboot the system I lose keyboard and it asks me to enter a run level. Obviously I can't troubleshoot more because I have no keyboard. What command should I use to create a RAID5 with more disk space (no hot spare) using 4 drives? My commands and install method work perfect with 3 drives but 4 and the system crashes upon reboot. Any tips?
