Do you have the ansible backtrace from the "ceph-iscsi-gw : igw_lun | configure luns (create/map rbds and add to lio)]" step? Have you tried using the stock v4.16 kernel (no need to use the one on shaman)?

I have the logfile, however there everything seems fine. The last lines are:
2018-06-28 17:25:36,876 igw_lun.py DEBUG : Check the rbd image size
matches the request
2018-06-28 17:25:36,904 igw_lun.py DEBUG : rbd image rbd.iscsi2342
size matches the configuration file request
2018-06-28 17:25:36,904 igw_lun.py DEBUG : Begin processing LIO mapping
2018-06-28 17:25:36,905 igw_lun.py INFO : (LUN.add_dev_to_lio)
Adding image 'rbd.iscsi2342' to LIO
2018-06-28 17:25:36,905 igw_lun.py DEBUG : control="max_data_area_mb=8"
