Storage-Related CLI Commands

You can use commands when working with storage specific to OpenStack.

For more information, see Cloud Platform Storage Configuration <storage-configuration-storage-resources>

Add, Modify, or Display Storage Backends

To list the storage backend types installed on a system:

~(keystone_admin)$  system storage-backend-list

+--------+---------------+--------+-----------+----+--------+------------+
| uuid   | name          |backend |state      |task|services|capabilities|
+--------+---------------+--------+-----------+----+--------+------------+
| 27e... |ceph-store     |ceph    |configured |None| None   |min_repli.:1|
|        |               |        |           |    |        |replicati.:1|
| 502... |shared_services|external|configured |None| glance |            |
+--------+---------------+--------+-----------+----+--------+------------+

To show details for a storage backend:

~(keystone_admin)$  system storage-backend-show <name>

For example:

~(keystone_admin)$  system storage-backend-show ceph-store
+--------------------+-------------------------------------+
|Property            | Value                               |

List Glance Images

You can use this command to identify the storage backend type for Glance images. (The column headers in the following example have been modified slightly to fit the page.)

~(keystone_admin)$ OS_AUTH_URL=http://keystone.openstack.svc.cluster.local/v3
~(keystone_admin)$  openstack image list
+----+------+-------+--------+-----------+------+--------+------------+-----------+
| ID | Name | Store | Disk   | Container | Size | Status | Cache Size | Raw Cache |
|    |      |       | Format | Format    |      |        |            |           | 
+----+------+-------+--------+-----------+------+--------+------------+-----------+
| .. | img1 | rbd   | raw    | bare      | 1432 | active |            |           |
| .. | img2 | file  | raw    | bare      | 1432 | active |            |           |
+----+------+-------+--------+-----------+------+--------+------------+-----------+
  • The value rbd indicates a Ceph backend.
  • You can use the –long option to show additional information.

Show Glance Image

You can use this command to obtain information about a Glance image.

~(keystone_admin)$ OS_AUTH_URL=http://keystone.openstack.svc.cluster.local/v3
~(keystone_admin)$  openstack image-show <<image-id>>
+------------------+--------------------------------------+
| Property         | Value                                |
+------------------+--------------------------------------+
| checksum         | c11edf9e31b416c46125600ddef1a8e8     |
| name             | ubuntu-14.014.img                    |
| store            | rbd                                  |
| owner            | 05be70a23c81420180c51e9740dc730a     |
+------------------+--------------------------------------+

The Glance store value can be either file or rbd. The rbd value indicates a Ceph backend.
