"rbd ls" operation doesn't depend on the kernel. What do you mean by "can't do" - no output at all? Something similar was reported here [1]. What's the output of "rados -p <your rbd pool> stat rbd_directory"? > 'rbd mount' does not work with the stock 3.10 kernel, but works with the 4.6 > kernel. Anything in dmesg on 3.10?
