Storage Pools
|
|
===============
|
|
|
|
Ceph stores data in 'pools' within the OSDs. When you first deploy a cluster
|
|
without specifying pools, Ceph uses the default pools for storing data.
|
|
To organize data into pools, see the `rados`_ command for details.
|
|
|
|
You can list, create, and remove pools. You can also view the pool utilization
|
|
statistics.
|
