All the service in the cluster is normal，I tried difference version of ceph-iscsi，but it not works。

Start with ceph_iscsi_config/lun.py, especially allocate and _add_dev_to_lio_user_rbd, using the traceback's /disks create pool=rbd image=disk_1 size=1G reproduction. Trace the LIO backstore construction and the unexpected control argument; done means the disk create request completes without the exception.
