Hello guys! NetApp NFS job is facing an error in test_compare_volume_stats_value [1] after the patch was merged [2]. We configure our backends by using "nfs" as storage_protocol and  I believe the patch added preferred naming as "NFS", but enabling scheduler to work with a list of variants [NFS, nfs] and break the test with "NFS" vs "nfs". Is the scheduler not able to work with both variants (NFS, nfs) without problems?  If so, do we need to change the way that this test [3] is being executed?
