Description of problem: When attaching a FC device, nova-compute will assign only one /dev/sd* device even though there are 4 paths (or more) and a DM-* device . Shouldn't nova-compute leverage using a dm-* device instead of one of the underlying device ? If that path fails, then the VM will lose the volume as if it was using dm-* instead, it would simply failover one of the 3 remaining paths. When the volume is detached, it's only deleting one of the device instead of all device. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Create volume 2. Attach volume 3. Detach volume Actual results: Only one device is used/delete Expected results: The DM device is used/ only one device is deleted instead of 5 Additional info:
