Subject Can't attach volumes with AMI ebs-io
Date Thu, 12 Feb 2015 04:30:32 GMT
Hi

I am trying to use

template.getOptions().as(EC2TemplateOptions.class).mapNewVolumeToDeviceName("/dev/sdm",
100, true );

to attach another volume to an instance. But I did realize that if the AMI
is ebs, the volume is created, but if the AMI is ebs-io, the volume is not
created.

Any ideas how to solve this problem ?

Code examples:

AMI EBS (works)

        final String POLL_PERIOD_TWENTY_SECONDS =
String.valueOf(SECONDS.toMillis(20));

        Properties overrides = new Properties();
        overrides.setProperty(ComputeServiceProperties.POLL_INITIAL_PERIOD,
POLL_PERIOD_TWENTY_SECONDS);
        overrides.setProperty(ComputeServiceProperties.POLL_MAX_PERIOD,
POLL_PERIOD_TWENTY_SECONDS);

        Iterable<Module> modules = ImmutableSet.<Module> of(new
SshjSshClientModule(), new SLF4JLoggingModule());
        //Iterable<Module> modules = ImmutableSet.<Module> of(new
SshjSshClientModule());

        ComputeServiceContext context = ContextBuilder.newBuilder("aws-ec2")
                .credentials("xx", "xx/")
                .modules(modules)
                .overrides(overrides)
                .buildView(ComputeServiceContext.class);
        ComputeService computeService = context.getComputeService();

//      UBUNTU
        Template template = computeService.templateBuilder()
                .locationId("us-east-1")
                .imageId("us-east-1/ami-7c807d14")
                .hardwareId("t1.micro")
                .build();


        template.getOptions().as(EC2TemplateOptions.class).mapNewVolumeToDeviceName("/dev/sdm",
100, true );


        Set<? extends NodeMetadata> nodes =
computeService.createNodesInGroup("m456", 1, template);

        for (NodeMetadata nodeMetadata : nodes) {
            String publicAddress =
nodeMetadata.getPublicAddresses().iterator().next();
            //String privateAddress =
nodeMetadata.getPrivateAddresses().iterator().next();
            String username = nodeMetadata.getCredentials().getUser();
            String password = nodeMetadata.getCredentials().getPassword();
            // [...]
            System.out.println(String.format("ssh %s@%s  %s",
username, publicAddress, password));
            System.out.println(nodeMetadata.getCredentials().getPrivateKey());


        }

EBS IO (Does not work)

        final String POLL_PERIOD_TWENTY_SECONDS =
String.valueOf(SECONDS.toMillis(20));

        Properties overrides = new Properties();
        overrides.setProperty(ComputeServiceProperties.POLL_INITIAL_PERIOD,
POLL_PERIOD_TWENTY_SECONDS);
        overrides.setProperty(ComputeServiceProperties.POLL_MAX_PERIOD,
POLL_PERIOD_TWENTY_SECONDS);

        Iterable<Module> modules = ImmutableSet.<Module> of(new
SshjSshClientModule(), new SLF4JLoggingModule());
        //Iterable<Module> modules = ImmutableSet.<Module> of(new
SshjSshClientModule());

        ComputeServiceContext context = ContextBuilder.newBuilder("aws-ec2")
                .credentials("xx", "yy/")
                .modules(modules)
                .overrides(overrides)
                .buildView(ComputeServiceContext.class);
        ComputeService computeService = context.getComputeService();

//      UBUNTU
        Template template = computeService.templateBuilder()
                .locationId("us-east-1")
                .imageId("us-east-1/ami-38834650")
                .hardwareId("t1.micro")
                .build();


        template.getOptions().as(EC2TemplateOptions.class).mapNewVolumeToDeviceName("/dev/sdm",
100, true );


        Set<? extends NodeMetadata> nodes =
computeService.createNodesInGroup("m456", 1, template);

        for (NodeMetadata nodeMetadata : nodes) {
            String publicAddress =
nodeMetadata.getPublicAddresses().iterator().next();
            //String privateAddress =
nodeMetadata.getPrivateAddresses().iterator().next();
            String username = nodeMetadata.getCredentials().getUser();
            String password = nodeMetadata.getCredentials().getPassword();
            // [...]
            System.out.println(String.format("ssh %s@%s  %s",
username, publicAddress, password));
            System.out.println(nodeMetadata.getCredentials().getPrivateKey());


        }


Note: I am using the official ubuntu images at
http://cloud-images.ubuntu.com/releases/14.04/release-20140607.1/published-ec2-release.txt.orig

Any help is appreciated!

Regards,
Ruben
