Volumes are the Block Storage devices that you attach to instances to
enable persistent storage. Users can attach a volume to a running
instance or detach a volume and attach it to another instance at any
time. For information about using the dashboard to create and manage
volumes as an end user, see the OpenStack End User Guide </user/manage-volumes>.

As an administrative user, you can manage volumes and volume types
for users in various projects. You can create and delete volume types,
and you can view and delete volumes. Note that a volume can be encrypted
by using the steps outlined below.
