Version-Release number of selected component (if applicable):
RHOS-17.1-RHEL-9-20230712.n.1

How reproducible:
50%

Steps to Reproduce:
1. Deploy 17.1 with NVMeOF Cinder backend enabled
2. Create a server and volume and attach the volume to the server
3. Resize the server

Actual results:
Server resize is failing due to attach volume not being found during resize process

Expected results:
server resize action is successful
