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__ type
 

However 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.
