No Huddle Offense

SmartStack = SmartOS + OpenStack (Part 3)

This is the third part os the blog post series. Previous parts can be found here: 1 2

To ensure the proper startup of nova-compute we will register it using SMF – this will also increase the dependability of the services. To start we will define a properties file for nova-compute – we will be using a glance and rabbitMQ host which run on a different host:

--connection_type=fake
--glance_api_servers=192.168.56.101:9292
--rabbit_host=192.168.56.101
--rabbit_password=foobar
--sql_connection=mysql://root:foobar@192.168.56.101/nova

We will store this contents in the file /data/workspace/smartos.cfg. We will also create an XML file with the manifest definition – it has some dependencies defined:

<?xml version='1.0'?>
<!DOCTYPE service_bundle SYSTEM '/usr/share/lib/xml/dtd/service_bundle.dtd.1'>
<service_bundle type='manifest' name='openstack'>
  <service name='openstack/nova/compute' type='service' version='0'>
    <create_default_instance enabled='true'/>
    <single_instance/>
    <dependency name='fs' grouping='require_all' restart_on='none' type='service'>
      <service_fmri value='svc:/system/filesystem/local'/>
    </dependency>
    <dependency name='net' grouping='require_all' restart_on='none' type='service'>
      <service_fmri value='svc:/network/physical:default'/>
    </dependency>
    <dependency name='zones' grouping='require_all' restart_on='none' type='service'>
      <service_fmri value='svc:/system/zones:default'/>
    </dependency>
    <exec_method name='start' type='method' exec='/usr/bin/nohup /data/workspace/nova/bin/nova-compute --flagfile=/data/workspace/smartos.cfg &amp;' timeout_seconds='60'>
      <method_context>
        <method_environment>
          <envvar name="PATH" value="/ec/bin/:$PATH"/>
        </method_environment>
      </method_context>
    </exec_method>
    <exec_method name='stop' type='method' exec=':kill' timeout_seconds='60'>
      <method_context/>
    </exec_method>
   <stability value='Unstable' />
  </service>
</service_bundle>

This can be imported using the svccfg command. After doing so we can use al the known commands to verify all is up and running:

[root@08-00-27-e3-a9-19 /data/workspace]# svcs -p openstack/nova/compute
STATE          STIME    FMRI
online         14:04:52 svc:/openstack/nova/compute:default
               14:04:51     3142 python

Now up to integrate vmadm…
