Retype In-use Ceph > Ceph doesn't actually retype the volume

Solution Verified - Updated -


  • When trying to retype a Ceph volume from one backend to another, such as SAS to NVME. Any volumes that are in-use wont throw immediate errors, but they don't get retyped. Rather, they just show migration_status: error
$ cinder show my_vol
