You should have "/var/log/ansible-module-igw_config.log" on the target machine that hopefully includes more information about why the RBD image is missing from the TCM backend. In the past, I've seen issues w/ image features and image size mismatch causing the process to abort.

Hi,
I'm trying to setup iSCSI using ceph-ansible (stable-3.1) branch with
one iscsi gateway. The Host is a CentOS 7 host and I use the packages
from the Centos Storage SIG for luminous. Additionally I have installed:
ceph-iscsi-cli Version 2.7 Release 13.gb9e48a7.el7
ceph-iscsi-config Version 2.6 Release 15.ge016c6f.el7
from the iscsi project at shaman.ceph.com.
The python-rtslib version on the host is 2.1.fb67 Release 10.g7713d1e
also from shaman. The running kernel version is 4.15.0-ceph-g1c778f43da52.
The ansible process stops at TASK [ceph-iscsi-gw : igw_lun | configure
luns (create/map rbds and add to lio)] complaining about file not found
while caused by the self._enable function in tcm.py. That is due to the
directory /sys/kernel/config/target/core/user_0/ is completely missing
at this step.
Do you have any ideas how to fix or debug this further?
Regards
Bernhard
