Configuration

===============
|
|
|
|
Ceph can run with a cluster containing thousands of Object Storage Devices
|
|
(OSDs). A minimal system will have at least two OSDs for data replication. To
|
|
configure OSD clusters, you must provide settings in the configuration file.
|
|
Ceph provides default values for many settings, which you can override in the
|
|
configuration file. Additionally, you can make runtime modification to the
|
|
configuration using command-line utilities.
|
|
|
|
When Ceph starts, it activates three daemons:
|
|
|
|
- ``ceph-mon`` (mandatory)
|
|
- ``ceph-osd`` (mandatory)
|
|
- ``ceph-mds`` (mandatory for cephfs only)
|
|
|
|
Each process, daemon or utility loads the host's configuration file. A process
|
|
may have information about more than one daemon instance (*i.e.,* multiple
|
|
contexts). A daemon or utility only has information about a single daemon
|
|
instance (a single context).
|
|
|
|
.. note:: Ceph can run on a single host for evaluation purposes.
