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
