krbd doesn't yet support several RBD features, including journaling [1]. The only current way to use object-map, fast-diff, deep-flatten, and/or journaling features against a block device is to use "rbd device map --device-type nbd <image-spec>" (or use a TCMU loopback device to create an librbd-backed SCSI block device).

I upgraded the kernel from 4.4 to 4.18 but I still get the same error message.
