graphical installer crashed.

[HankB]

Installing to /dev/sdb with /boot/efi on an MD RAID1 partition. Booted to live environment, apt upgrade/update, install mdadm (and gparted) brought up the RAID and started the install. Selected /dev/md0 for EFI partition and /dev/sdb2 for '/' (formatted as EXT4) Selected /dev/sdb for GRUB installation.

Tried to boot from BIOS (UEFI boot manager) selecting "integrated RAID Controller 1: ubuntu" and got a "GRUB>" prompt. Seems like no way to boot from second drive via the UEFI BIOS. Swapped drives with same result.

or similar hoping

Can you post the output of mdadm -D /dev/md0?

[HankB (hbarta)]

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@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.

Can you run sudo grub-probe /boot/efi?

[HankB (hbarta)]

I have handed this off to another user and no longer have access to it.
