Installation on ppc64le stuck when trying to setup LVM

[Guilherme Tiaki Sato]

I’am using Ubuntu 16.04 Netboot installer.

During the disk partitioning:

I have two disks, create an empty partition table on both and set both to be used entirely as physical volume for LVM.

Select "Configure the Logical Volume Manager".
Create a volume group using the two disks.
Create two logical volumes: one 8MB and the other using the rest of the space.
Finish configuring LVM.

Set the first logical volume "Use as" to "Use the partition as a PowerPC PReP boot partition".

This is followed by an error screen (attached).

After this I get stuck in the partitioning and can no longer continue the installation or change the partitioning.

Hello Guilherme, could you please attach the installation logs? You can do it by exiting to shell, at d-i, and grabbing the logs at /var/log.

This is certainly a bug, but it is user error to configure an LVM volume as the prep partition; the prep partition must be a disk partition visible from firmware.

I believe this bug does not occur when using guided partitioning.

Yes, you're right. It works fine when using guided partitioning.
