I tried to install opensuse on my nvidia fakeraid raid1 array

Reproducible: Always

Steps to Reproduce:
1. create a fakeraid raid1 array
2. try to install opensuse on a partition on that array
3. In Partitioner try to use a partition of that array without formatting it
4. Perform the Installation
Actual Results:  
partitioner does not detect filesystems or sizes of the partitions on the fakeraid array and complains when trying to use a partition without formatting it, claiming that it doesnt know the filesystem.

installation fails to format any partitions
installation fails to mount any partition
Installation fails

Expected Results:  
Partitioner showing the partitions correct and allowing partitiosn to be not formatted
Installer formatting and mounting / properly

Here is what I did to overcome the issues:
when the error appear that it couldnt fomrat the partition
I went to a shell and ran this:
dmraid -ay # to start the raid array. I found, that it wasnt activated(or maybe there were just no partitions shown, dont remember)
I then manually formatted my partition to ext4
I also made a symlink
ln -sv /dev/mapper/nvidia_bbbdidfcp4 /dev/mapper/nvidia_bbbdidfc_part4
I realized the installer expects the partition name to contain this "_part" while dmraid will not name them thus by default.
Installation then went through till installing grub(which might be another issue) or caused by the same
