Open Stack

I have applied the proposed patch for the setattr launch error


I patch works, but the launch still fails.

The stack trace just says the creation failed.

I can see in horizon that it makes it past the "waiting" log message.

My suspicion is with volumes.attach() below since the output from the
cluster_create contains

"volume_mount_prefix": "/volumes/disk",


I am using the vmware machine as configured in the guide, but
locate /volumes/disk returns nothing.

--- here is instances.py where the exception is thrown

def create_cluster(cluster):
    ctx = context.ctx()
    try:
        # create all instances
        conductor.cluster_update(ctx, cluster, {"status": "Spawning"})
        LOG.info(g.format_cluster_status(cluster))
        _create_instances(cluster)

        # wait for all instances are up and accessible
        cluster = conductor.cluster_update(ctx, cluster, {"status":
"Waiting"})
        LOG.info(g.format_cluster_status(cluster))
        cluster = _await_instances(cluster)

        # attach volumes
        volumes.attach(cluster)

        # prepare all instances
        cluster = conductor.cluster_update(ctx, cluster,
                                           {"status": "Preparing"})
        LOG.info(g.format_cluster_status(cluster))

        _configure_instances(cluster)

    except Exception as ex:
        LOG.warn("Can't start cluster '%s' (reason: %s)", cluster.name, ex)

tips to debug?
