Hi Joshua, I was under the impression that kernel 3.10.0-693 will work with iscsi
Unfortunately I still cannot create a disk because qfull_time_out is not supported What am I missing / do it wrong ? 2018-01-19 15:06:45,216 INFO [lun.py:601:add_dev_to_lio()] - (LUN.add_dev_to_lio) Adding image 'rbd.disk2' to LIO 2018-01-19 15:06:45,295 ERROR [lun.py:634:add_dev_to_lio()] - Could not set LIO device attribute cmd_time_out/qfull_time_out for device: rbd.disk2.
