Hello guys.
I update this error happened because when I destroy and redeploy I don't remove hosts and its initiator. just remove them, it will be ok.

Hello guys.
I am using kolla-ansible yoga to deploy an openstack cluster, but when I launch an instance with volume, it has errors.
but I can create volume first and boot from it. I am using Powerstore 5000Tb. Is it a bug?
