To create an EBS Volume you need to specify the following items:

  • Nickname - A short name that lets you recognize the volume.
  • Description - Describe the purpose of the volume and any other useful information. This is for documentation purposes only and does not affect behavior.
  • Snapshot - An EBS Snapshot that you would like to build a volume from. You are not required to provide a snapshot if you wish to create an empty volume. Simply select the (-none-) option in order to create a blank volume.
  • Zone - The Availability Zone that you would like to place your volume into. You can only attach a volume to an instance that is in the same availability zone. Before creating a new volume you may need to check the availability zone of the instance that you want to attach the new volume to because once a volume is created, it cannot be moved into a different availability zone.
  • Size in GB - The size of the volume. If you are creating the volume based on an existing snapshot, a minimum size will be displayed. (Valid range: 1GB - 1TB) NOTE: If you are choosing an IOPS volume type, specify at least 10GBs in size, since that is the minimum size for the instance.
  • Type - The type of the EBS volume. Choose 'standard' for a standard EBS volume and 'io1' for a Provisioned IOPS volume.
  • IOPS - This field will appear if 'io1' is chosen as a Type. The IOPS rate that you would like this volume to be provisioned as. The IOPS provisioned ratio of the volume size can be a maximum of 10 and the range to create a Provisioned IOPS volume is 100 IOPS and 10GB up to 2,000 IOPS and 200GB.

The Elastic Block Store (EBS) provides persistent, high-performance, and high-availability block-level storage which you can attach to a running EC2 instance (in the same availability zone) in the form of volumes. There are two types of volumes you can create: Standard and Provisioned IOPS. A Standard volume is best suited for boot volumes and provides roughly 100 IOPS (Input/Output Per Second) on average. Provisioned IOPS volumes are designed to provide predictable, high performance I/O workloads that range up to 2,000 IOPS and are best suited for database workloads. Each EBS volume can be formatted and mounted as a file system. An EBS Volume can only be attached to a single instance at a time. Attach EBS Volumes to instances at run-time or boot-time. Multiple volumes can be mounted to the same instance. Take EBS Snapshots of a volume at a particular point in time and then create multiple volumes from a snapshot and place them into any zone. You can also see the lineage of a volume/snapshot to see when it was created, as well as any parent/child relationships.

Note: Changes to EBS Volumes, whether they are creations, attachments, detachments or deletions, often requires several minutes to take effect.

Lineage tab

The Lineage tab shows a chronological lineage of all created EBS volumes within the account. Select a volume to view a more detailed lineage report including attach/detach/snapshot actions.

An EBS Volume is a highly reliable and persistent storage volume that can be mounted to EC2 instances in the same availability zone.

Action Buttons

  • Attach now - Attach this volume to a server instance that is already operational. You will also have the option to configure the volume to be attached at boot time the next time the server is launched.
  • Attach on boot time - Attach this volume to the server instance (at boot time) the next time the server is launched.
  • Detach - Unmount and detach an EBS volume from a running server instance. The volume will not be deleted.
  • Forced Detach - If you've detached a volume and it appears as though the volume is stuck, you can forcibly detach it from the instance. When you perform a regular detach action, it will wait for all data to by copied to the volume before the it's detached. However, a forced detach will be immediately unplugged from the instance, so some data loss may occur.
  • Snapshot - When you attach a snapshot to a server instance, a volume of that snapshot will be created and attached to the instance.
  • Delete - Delete the volume. You cannot delete a volume that is currently attached to a running server instance. You must first detach it before you can delete it.

Lineage tab

The Lineage tab shows the lineage of a volume. You can see which snapshot the volume was originally created from, as well as a history of all snapshots and attach/detach actions.

Clouds > AWS Region > EBS Volumes > Show > Lineage tab

Snapshots tab

The Snapshots tab shows the snapshot history of the volume. Delete unnecessary snapshots or create new volumes from one of the snapshots.

Clouds > AWS Region > EBS Volumes > Show > Snapshots tab

Info tab

The Info tab shows general information about the volume including its availability status (available, in-use) and attachment status (attached, not attached). You can also see if the volume was created from scratch or from an existing snapshot. Once a volume is created, its details cannot be edited. For example, you can't move an EBS volume into a different availability zone. If you want to make the volume available in a different availability zone you will need to create a snapshot of it and then create a volume from the snapshot in the desired availability zone.

Although you can only apply tags in the Dashboard, the tags of an EBS Volume will show up in a tag search issued from the API. A user will still need 'actor' user role privileges in a RightScale account in order to add/edit/delete a tag in the RightScale Dashboard.

Clouds > AWS Region > EBS Volumes > Show > Info tab

Servers tab

The Servers tab shows the volume's current attachment settings. If the volume is currently attached to a server you can take a snapshot or detach the volume. You can also configure a volume so that it will automatically be attached to a server at boot time.
