Nah, Luminous is the way to go here. I started playing with the iSCSI gateway, too. It's certainly a quite bumpy road, at least for now. You should be able to get things running up to the point where you try to add RBD volumes to the gateways. This will fail with a "Kernel not supported" error message, caused by the running kernel not supporting the qfull_time_out attribute. While the Ceph docs state you need Linux 4.14+, the required patches never ended up in 4.14, as the author discovered an issue with them. Mike posted a new series to target-devel but they won't land in mainline before 4.16. I initially interpreted the "RHEL/CentOS 7.4; or Linux kernel v4.14 or newer" part as saying that the EL7 kernel had those patches applied/backported. Grepping through the big monolithic tarball contained within kernel-3.10.0-693.5.2.el7.src.rpm, that doesn't seem to be the case. I might have missed something (just started playing with the iSCSI stuff), but AFAICT the Ceph docs are simply incorrect on this matter. So, if you want to test the iSCSI gateway, the way forward is probably to pick up those TCMU kernel patches and start testing. What are you running your gateways on?
