  1. Define the server name by uncommenting the following line

    # Specify the associated DAOS systems.
# Name must match name specified in the daos_server.yml file on the server.
#
# NOTE: Changing the name is not supported in DAOS 1.0, it must be daos_server
#
# default: daos_server
name: daos_server

  2. Define the destination port by uncommenting the following line

    # Default destination port to use when connecting to hosts in the hostlist.
# default: 10001
port: 10001

  3. Define the host list by uncommenting the following line.  This list must contain all the server nodes.

    # Hostlist, a comma separated list of addresses (hostnames or IPv4 addresses).
# default: ['localhost']
hostlist: ['node-4', 'node-5', 'node-6']

  4. Define the transport configuration (certificate files) by uncommenting the following lines

    ## Transport Credentials Specifying certificates to secure communications

transport_config:
# In order to disable transport security, uncomment and set allow_insecure
# to true. Not recommended for production configurations.
allow_insecure: false

# Custom CA Root certificate for generated certs
ca_cert: /etc/daos/certs/daosCA.crt
# Admin certificate for use in TLS handshakes
cert: /etc/daos/certs/admin.crt
# Key portion of Admin Certificate
key: /etc/daos/certs/admin.key

  5. Completed control yaml file should look something like this:

# path specified through the -o option of the dmg command line.
# Otherwise, /etc/daos/daos_control.yml is used.

#
# Although not supported for now, one might want to connect to multiple
# DAOS installations from the same node in the future.
