I am using openstack latest victoria release on ubuntu 20.04. The instance is launched from horizon and storage types are created.
From UI,
boot source is: IMAGE
Create New Volume: Yes
Size: 5
Below is the output that I have set default volume type in cinder.conf
root@storage:/etc/cinder# grep default_volume_type cinder.conf
default_volume_type = lvm_backed
However from openstack cli I have created a volume from image in lvm_backend storage type and booted a instance from it. It goes successful.
I haven't set any property in image. Below is the image output.

Hi Malik,I would like to know which openstack release is used.On Thu, Feb 18, 2021 at 4:41 PM Malik Obaid <malikobaidadil@gmail.com> wrote:Hi,
I am creating nova instance with cinder backed iscsi storage. I have created multiple storage types. But my launched instance from image use storage type __DEFAULT__ for flavor's root volume.
Is the instance launched via horizon or CLI and if CLI which command is used?I have changed default_volume_type to mystoragetype in cinder.conf but instances root volume still goes in __DEFAULT__ storage type.
This should not happen since default_volume_type has a higher preference than the __DEFAULT__ typeHowever new volume creation in mystoragetype is successful.
Need help, how can I set instance root volume storage type during its deployment ?
My guess is that the image used has ``cinder_img_volume_type`` property set to __DEFAULT__ else there is no way cinder prefers __DEFAULT__ type over any other in this case.Also if you're using victoria release and no volume is using the __DEFAULT__ type then you can delete it as well.Regards,
