Appendix F. Overriding Ceph Default Settings
Unless otherwise specified in the Ansible configuration files, Ceph uses its default settings.
Because Ansible manages the Ceph configuration file, edit the /etc/ansible/group_vars/all.yml file to change the Ceph configuration. Use the ceph_conf_overrides setting to override the default Ceph configuration.
Ansible supports the same sections as the Ceph configuration file; [global], [mon], [osd], [mds], [rgw], and so on. You can also override particular instances, such as a particular Ceph Object Gateway instance. For example:
###################
# CONFIG OVERRIDE #
###################
ceph_conf_overrides:
client.rgw.rgw1:
log_file: /var/log/ceph/ceph-rgw-rgw1.logAnsible does not include braces when referring to a particular section of the Ceph configuration file. Sections and settings names are terminated with a colon.
Do not set the cluster network with the cluster_network parameter in the CONFIG OVERRIDE section because this can cause two conflicting cluster networks being set in the Ceph configuration file.
To set the cluster network, use the cluster_network parameter in the CEPH CONFIGURATION section. For details, see Section 3.2, “Installing a Red Hat Ceph Storage Cluster”.
