Hi All,
I've followed the instructions on the CEPH Doco website on Configuring
the iSCSI Target. Everything went AOK up to the point where I try to
start the rbd-target-api service, which fails (the rbd-target-gw service
started OK).
A `systemctl status rbd-target-api` gives:
~~~

This `iscsi-gateway.cfg` file reads:
~~~
[config]
cluster_name = ceph
gateway_keyring = ceph.client.admin.keyring
# API settings.
# The api supports a number of options that allow you to tailor it to your
# local environment. If you want to run the api under https, you will
need to
# create crt/key files that are compatible for each gateway node (i.e. not
# locked to a specific node). SSL crt and key files *must* be called
# iscsi-gateway.crt and iscsi-gateway.key and placed in /etc/ceph on *each*
# gateway node. With the SSL files in place, you can use api_secure = true
# to switch to https mode.
api_secure = false
# Additional API configuration options are as follows (defaults shown);
# api_user = admin
# api_password = admin
# api_port = 5000
trusted_ip_list = 192.168.1.101,192.168.1.101,192.168.1.101
# Refer to the ceph-iscsi-config/settings module for more options
~~~
192.168.1.101 is the ip address for the ceph-host1.mydomain.local (and
similarly for the other ip addresses / hostnames of the other 2 nodes,
which are yet to be installed).
The iSCSI Node is co-located on an OSD Node.
The Cluster is working (apart form the iSCSI part, of course).
So, could someone be kind enough to point out what I'm missing (ie
what's wrong)? - Thanks in advance
Dulux-Oz
