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.

|
|
|
|
|
|
|
|
|
|
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.

|
2012-09-06 00:22:32 +00:00
|
|
|
|
|
|
|
|
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.

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