1 - Create and Attach an EBS Volume

The following example shows how to create a 10 gigabyte EBS volume and attach it to a running instance called i-00000000 running in availability zone zone1 .

Create a new EBS volume in the same availability zone as the running instance.

euca-create-volume --availability-zone zone1 --size 10

The command displays the ID of the newly-created volume. Attach the newly-created volume to the instance, specifying the local device name /dev/sdf .

euca-attach-volume vol-00000000 -i i-00000000 -d /dev/sdf

You’ve created a new EBS volume and attached it to a running instance. You can now access the EBS volume from your running instance.

2 - List Available EBS Volumes

You can use the Eucalyptus command line tools to list all available volumes and retrieve information about a specific volume.

To get a list of all available volumes in your Eucalyptus cloud, enter the following command:

euca-describe-volumes

To get information about one specific volume, use the euca-describe-volumes command and specify the volume ID.

euca-describe-volumes vol-00000000

3 - Detach an EBS Volume

To detach a block volume from an instance:

Enter the following command:

euca-detach-volume <volume_id>



euca-detach-volume vol-00000000

4 - Create a Snapshot

The following example shows how to create a snapshot.

Enter the following command:

euca-create-snapshot <volume_id>



euca-create-snapshot vol-00000000

5 - List Available Snapshots

You can use the Eucalyptus command line tools to list available snapshots and retrieve information about a specific snapshot.

To get a list of all available snapshots in your Eucalyptus cloud, enter the following command:

euca-describe-snapshots

To get information about one specific snapshot, use the euca-describe-snapshots command and specify the snapshot ID.

euca-describe-snapshots snap-00000000

6 - Delete a Snapshot

The following example shows how to delete a snapshot.

Enter the following command:

euca-delete-snapshot <snapshot_id>
