Fixed In Version: ceph-14.2.4
Doc Type: Enhancement
Doc Text:
.Configuration is now stored in Monitors accessible by using `ceph config` In this release, {product} centralizes configuration in Monitors instead of using the Ceph configuration file (`ceph.conf`). Previously, changing configuration included manually updating `ceph.conf`, distributing it to appropriate nodes, and restarting all affected daemons. Now, the Monitors manage a configuration database that has the same semantic structure as `ceph.conf`. The database is accessible by the `ceph config` command. Any changes to the configuration are applied to daemons or clients in the system immediately and restarting them is no longer needed. Use the `ceph config -h` command for details on the available set of commands. Note that a Ceph configuration file is still required to identify the Monitors nodes.

Description Josh Durgin 2019-02-09 01:50:15 UTC 
ceph.conf is no longer necessary. Configuration is stored in the monitors, and changes there are propagated to the rest of the cluster.

When a client or daemon starts, it can still use a local ceph.conf or DNS to find the monitor addresses or override the central config, but the usual case should be a minimal ceph.conf and reading the settings from the monitors.

Updating the QA Contact to a Hemant. Hemant will be rerouting them to the appropriate QE Associate.
