Using 'targetcli /backstores/block/ create name dev [readonly=true]' to set block with "ro write-thru" stat.

however, the initiator can still write to the iscsi device.

and I also find something similar,  https://bugzilla.redhat.com/show_bug.cgi?id=1036052

Is this not supported current?

the version i am using is :

targetcli-2.1.fb37-3.el7.src.rpm

python-configshell-1.1.fb14-1.el7.src.rpm

python-rtslib-2.1.fb50-1.el7.src.rpm
