Openstack with Microstack, I can't make empty Volume

Question

I'm a beginner at Openstack. I have an Ubuntu Server on a VM and on it, I installed Openstack with Microstack. Everything looks fine but I cannot make a Volume. It gives me this error:

schedule allocate volume: Could not find any available weighted backend.

I looked up everywhere for a solution but can't understand what is the issue.

Answer 1

microstack disabled cinder blockstorage service, and you should enable it during initializing. Further more, microstack can only use loop device file as backend.

sudo microstack init --auto --control \
 --setup-loop-based-cinder-lvm-backend \
 --loop-device-file-size 50
