Hi, We haven't tested this, and we do not have any code to handle nvme/tcp drivers, only iscsi and rbd. Given the path seen in the logs '/dev/mapper', it looks like it might require code changes to support this. Can you share cinderlib[1] and engine logs to see what is returned by the driver? I may be able to estimate what would be required (it's possible that it would be enough to just change the handling of the path in the engine)
