[Bug 1721317] Re: graphical installer crashed.

[HankB]

I needed to get the install done so I went ahead and did a more normal
install with '/boot/efi' in an normal partition on the first disk. After
the install, I created a matching partition on the second drive, copied the
/boot/efi partition to that and then created a (degraded RAID) on the first
drive. (At this point I had destroyed /dev/md0 and recreated it.) I then
copied the data back to the RAID partition on the first drive, unmounted
the partition on the second and added it to complete the RAID1. The
partition was created as /dev/md0 (using 0.90 metadata) and after reboot
came up as /dev/md127. Other than that, it seems to work. Surprisingly the
block ID for /dev/md127 and the original EXT4 /boot/efi matched. But this
is all after the crash that triggered the bug report.

The command used to create the RAID device would have used the same
parameters as

root at androidlx01:~# mdadm --create /dev/md0 --metadata=0.90 -l raid1 -f -n
1 /dev/sda1

mdadm: /dev/sda1 appears to be part of a raid array:

      level=raid0 devices=0 ctime=Wed Dec 31 19:00:00 1969

Continue creating array? y

mdadm: array /dev/md0 started.

root at androidlx01:~# cat /proc/mdstat

md0 : active raid1 sda1[0]
