openstack-nova-metadata-api dead but pid file exists

Question

Hi Guys,

I am trying to see metadata status of nova service. But It shows me the below error.

$ service openstack-nova-metadata-api status 
openstack-nova-metadata-api dead but pid file exists 

And the log file /var/log/nova/metadata-api.log reveled the below message

ERROR nova.wsgi [-] Could not bind to 0.0.0.0:8775 CRITICAL nova [-] error: [Errno 98] Address already in use.

Thank You

Hi@akhtar,

Surprisingly, the service ‘openstack-nova-metadata-api‘ was already running. Because, ‘openstacknova-api‘ starts ‘metadata-api‘ service along with it and thus the service ‘metadata-api‘ fails to bind to the port. All you need to do is, check if ‘nova-api’ is configured to start ‘metadata-api’ along with it. To do that

$ Open /etc/nova/nova.conf 

And lookout for ‘enabled_apis = osapi_compute,metadata‘ If you find metadata in enabled_apis, then whenever nova-api is started, it will also start metadata api.

Thank You
