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

  25
  26 Once you have your cluster up and running, you may begin working with data
  27 placement. Ceph supports petabyte-scale data storage clusters, with storage
  28 pools and placement groups that distribute data across the cluster using Ceph's
  29 CRUSH algorithm.

  48
  49 Low-level cluster operations consist of starting, stopping, and restarting a
  50 particular daemon within a cluster; changing the settings of a particular
  51 daemon or subsystem; and, adding a daemon to the cluster or removing a  daemon
  52 from the cluster. The most common use cases for low-level operations include
  53 growing or shrinking the Ceph cluster and replacing legacy or failed hardware
  54 with new hardware.

  70 Ceph is still on the leading edge, so you may encounter situations that require
  71 you to evaluate your Ceph configuration and modify your logging and debugging
  72 settings to identify and remedy issues you are encountering with your cluster.
