Created attachment 631639 [details] logs Description of problem: I upgraded my 3.0 setup to 3.1 but did not update the hosts/Cluster or DC to 3.1 and I was able to create a floating disk and attach it to a vm. Version-Release number of selected component (if applicable): 3.0 -> si21.1 How reproducible: 100% Steps to Reproduce: 1. upgrade a 3.0 setup to si21.1 2. leave hosts/DC/Cluster with 3.0 level. 3. create a floating disk -> attach to vm Actual results: we can create and attach a floating disk with compatibility of 3.0 Expected results: this feature is supported for 3.1 only so we should allow this until all DC is updated to 3.1 Additional info: logs
I actually see no reason to block this in 3.0 (vdsm doesn't care so host compatibility is not an issue). Checked the code as well and I couldn't find any issue.
