|
|
|
|
High-level cluster operations consist primarily of starting, stopping, and
|
|
restarting a cluster with the ``ceph`` service; checking the cluster's health;
|
|
and, monitoring an operating cluster.

</td><td><h3>Data Placement</h3>
|
|
|
|
Once you have your cluster up and running, you may begin working with data
|
|
placement. Ceph supports petabyte-scale data storage clusters, with storage
|
|
pools and placement groups that distribute data across the cluster using Ceph's
|
|
CRUSH algorithm.

</td></tr><tr><td><h3>Authentication and Authorization</h3>
|
|
|
|
Once you have data placement policies in place, you can begin creating users
|
|
and assigning them capabilities, such as the ability to read and write data
|
|
to one or more pools, or the cluster as a whole.

</td><td><h3>Daemon Operations</h3>
|
|
|
|
Low-level cluster operations consist of starting, stopping, and restarting a
|
|
particular daemon within a cluster; changing the settings of a particular
|
|
daemon or subsystem; and, adding a daemon to the cluster or removing a daemon
|
|
from the cluster. The most common use cases for low-level operations include
|
|
growing or shrinking the Ceph cluster and replacing legacy or failed hardware
|
|
with new hardware.
