All primary shards are in same node. Why? Version 1.1.1

Hi everyone!

Im having a doubt regards my elastic cluster. Here is a picture of the head
plugin....

Here you can see that all primary shards are in the same node and not
distributed. I shutdown the master node to see if the primary shards were
going to be distributed in both nodes left but this is what happened.

All primary shards were allocated in a single node. Is this behaviour
right? I would prefer them to be distributed equally among all nodes so the
writing operations are not handled by a single one. Know how to do that?

This is my elasticsearch.yml

names.

cluster.name: mclics

action.auto_create_index: false

index.number_of_shards: 16

index.number_of_replicas: 2

action.disable_delete_all_indices: true

path.data: /mnt/elasticsearch

path.logs: /usr/local/log

bootstrap.mlockall: true

gateway.recover_after_nodes: 2

gateway.expected_nodes: 3

discovery.zen.minimum_master_nodes: 1

discovery.zen.ping.unicast.hosts: [##hosts##]

Thanks,
Santiago!

Primary shards are addressed first when writing, but it is a myth they do
all the writing. Secondary shards do the writing too, but only some milli
seconds later. There is nothing to worry about.
