I want to export ceph rbd via iscsi。
ceph version is 10.2.11，centos 7.5 kernel 3.10.0-862.el7.x86_64，
and i also installed tcmu-runner、targetcli-fb、python-rtslib、ceph-iscsi-config、 ceph-iscsi-cli。
but when i lanuch "create pool=rbd image=disk_1 size=10G" with gwcli it says "Failed : 500 INTERNAL SERVER ERROR".
below is content of /var/log/tcmu-runner.log:

in http://docs.ceph.com/docs/master/rbd/iscsi-overview/, it said required Ceph Luminous or newer。
Can someone tell me how to get lio to support jewel？
I am from China, my English is not very good, I hope you can understand。
Thanks for any help anyone can provide！！！
