I encountered an issue booting Ubuntu Server 16.04 when installing it on a SuperMicro server that had been configured with Software RAID 1. The operating system install script would detect that a RAID environment was active and it would install correctly, but when booting into the newly installed system I would be presented with a blank screen and a blinking cursor. Grub wasn’t even loading.

To solve this issue I booted into a live CD of Ubuntu 16.04 and did the following from the terminal:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

sudo su
mount /dev/mapper/<name of your raid partition> /mnt
cd /mnt
mount -t proc proc proc/
mount -t sysfs sys sys/
mount -o bind /dev dev/
mount --rbind /run run/
chroot .
grub-install /dev/sda
grub-install /dev/sdb
update-grub
exit
reboot

Note

Your /dev/sda and /dev/sdb might be different, please use the disks that were used to create the RAID drive

After restarting I was now greeted by the familiar Grub splash screen and Ubuntu proceeded to boot correctly.

P.S. I think it’s just better to use software RAID through Linux anyway, since FakeRAID is kind of the worst of both hardware and software implementation. ;)
