As far as I'm aware, we don't support creating multiple partitions in a single
RAID set; you should use LVM to do that. It's a bug in the partman RAID
integration code that it lets you do that.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

Thank you for the very detailed installer instructions.

I was able to follow them precisely, and to confirm that this step is no longer possible:
         ( RAID1 device #0 - 122.4 GB Software RAID device ) -->
        [ Create new empty partition table on this device? ] ( yes ) -->

When you select the RAID device in the installer, you are asked how you want to use it, and you are not allowed to create a new empty partition table on the device.

Thanks!
