Block Storage

Examples for Volumes and Snaphots:

#NOTE - attach/detach operations are implemented for the compute service as the OS API defines these operations as extensions to Openstack Compute.

vs = OpenStack::Connection.create({:username => "username", :api_key=>"pass", :auth_url => "https://region-a.geo-1.identity.hpcloudsvc.com:35357/v2.0/", :authtenant=>"username-default-tenant", :service_type=>"volume"})

Create a volume: - MUST specify display_name and size parameters... optional params are {:display_description, :metadata=>{:key=>val, ...}, :availability_zone, :volume_type }

volume = vs.create_volume({:display_name=>"marios volume", :size=>1, :display_description=>"some new volume bla"}) => #<OpenStack::Volume::Volume:0x8a3c534 @id=90805, @display_name="marios volume", @display_description="some new volume bla", @size=1, @volume_type=nil, @metadata={}, @availability_zone="nova", @snapshot_id="", @attachments=[{}], @created_at="2012-11-15 13:51:23">

volume.size => 1

volume.attachments => [{}]

List volumes:

vs.list_volumes #aliased as just 'volumes' ... vs.volumes => [#<OpenStack::Volume::Volume:0x8aad2e8 @id=90625, @display_name="marios volume", @display_description="attach test volume", @size=1, @volume_type=nil, @metadata={}, @availability_zone="nova", @snapshot_id="", @attachments=[{}], @created_at="2012-11-15 09:54:58">, #<OpenStack::Volume::Volume:0x8aad144 @id=90805, @display_name="marios volume", @display_description="some new volume bla", @size=1, @volume_type=nil, @metadata={}, @availability_zone="nova", @snapshot_id="", @attachments=[{}], @created_at="2012-11-15 13:51:23">]

Get a particular volume - must specify ID:

vs.get_volume(90625) #aliased as 'volume' => #<OpenStack::Volume::Volume:0x8abd4a4 @id=90625, @display_name="marios volume", @display_description="attach test volume", @size=1, @volume_type=nil, @metadata={}, @availability_zone="nova", @snapshot_id="", @attachments=[{}], @created_at="2012-11-15 09:54:58">

Delete a volume:

vs.delete_volume(90805) => true

Create a snapshot: - must specify display_name and volume_id parameters... optionally also :display_description

vs.create_snapshot({:volume_id=>"3b38b570-a4ff-4444-984a-3566cbdc8ab2", :display_name=>"marios_snapshot"}) => #<OpenStack::Volume::Snapshot:0xa0cfea4 @id=223, @display_name="marios_snapshot", @display_description=nil, @volume_id="3b38b570-a4ff-4444-984a-3566cbdc8ab2", @status="creating", @size=1, @created_at="2013-01-23 14:25:02.654217">

List snapshots: - aliased as just 'snapshots' ... vs.snapshots

vs.list_snapshots => [#<OpenStack::Volume::Snapshot:0x9a6e4fc @id="0e76dacb-2fcf-4565-84a3-aa3d7bd16224", @display_name="marios_snapshot", @display_description=nil, @volume_id="3b38b570-a4ff-4444-984a-3566cbdc8ab2", @status="creating", @size=1, @created_at="2013-01-23T14:18:13.000000">]

Get a specific snapshot: - aliased as 'snapshot'

vs.get_snapshot("0e76dacb-2fcf-4565-84a3-aa3d7bd16224") => #<OpenStack::Volume::Snapshot:0x9a890b8 @id="0e76dacb-2fcf-4565-84a3-aa3d7bd16224", @display_name="marios_snapshot", @display_description=nil, @volume_id="3b38b570-a4ff-4444-984a-3566cbdc8ab2", @status="creating", @size=1, @created_at="2013-01-23T14:18:13.000000">

Delete a snapshot:

vs.delete_snapshot("0e76dacb-2fcf-4565-84a3-aa3d7bd16224") => true
