$ . demo-openrc

Attach the volume to an instance
|
|
--------------------------------
|
|
|
|
#. Attach a volume to an instance:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack server add volume INSTANCE_NAME VOLUME_NAME
|
|
|
|
Replace ``INSTANCE_NAME`` with the name of the instance and ``VOLUME_NAME``
|
|
with the name of the volume you want to attach to it.
|
|
|
|
**Example**
|
|
|
|
Attach the ``volume1`` volume to the ``provider-instance`` instance:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack server add volume provider-instance volume1
|
|
|
|
.. note::
|
|
|
|
This command provides no output.
|
|
|
|
#. List volumes:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack volume list
|
|
|
|
+--------------------------------------+--------------+--------+------+--------------------------------------------+

|
| ID | Display Name | Status | Size | Attached to |

|
+--------------------------------------+--------------+--------+------+--------------------------------------------+
|
|
| a1e8be72-a395-4a6f-8e07-856a57c39524 | volume1 | in-use | 1 | Attached to provider-instance on /dev/vdb |
|
|
+--------------------------------------+--------------+--------+------+--------------------------------------------+
|
|
|
|
#. Access your instance using SSH and use the ``fdisk`` command to verify
|
|
presence of the volume as the ``/dev/vdb`` block storage device:
|
|
|
|
.. code-block:: console
|
|
|
|
$ sudo fdisk -l
|
|
|

You must create a file system on the device and mount it

to use the volume.
