Hi,

Today after a "yum update" which did upgrade parts of my
openstack installation and a reboot, I ended up with a "500
internal server error".

Here's last 100 log entried in httpd/error_log

centos 6.3 + epel (up to date :> ), selinux is in permissive
mode.

Hi,

Apparently nova-api doesn't start anymore. The initscript reports
"OK" but a second later it's dead: openstack-nova-api dead but pid
file exists

api.log fragment here http://fpaste.org/iZJr/

== 2013-01-12 11:45:20 19519 INFO nova.osapi_compute.wsgi.server
[-] (19519) wsgi starting up on http://0.0.0.0:8774/ 2013-01-12

2013-01-12 11:45:21 19488 INFO nova.service [-] Parent process has
died unexpectedly, exiting ==

But there is nothing listening on 8774 according to netstat and
lsof, so why is it complaining?

By any chance, did you an upgrade from Essex to Folsom release without
doing migration steps?

Another idea: Did you install OpenStack with openstack-demo-install?
Cinder/nova-volume requires a Volume group named cinder-volume
You might also want to stop nova-volume service and start
cinder-volumes/nova-volumes. If you installed OpenStack following the
TestDay page, cinder/nova-volume service is not started by default,
and also a volume group is not created persistantly.

Dashboard in it's current version requires a volume service enabled
(and running/answering to requests!)

An output of openstack-status and from keystone service-list will help
us here.

Hello Matthias,

This is not an upgrade from Essex, it was/is Folsom, "yum update" brought in some minor version changes. The software was installed via openstack-demo-install indeed, but I'm not using cinder or swift (the services are stopped). I have started however all cinder services and created the cinder-volumes vg, just to rule cinder out, no luck. Let's say the dashboard requires cinder/nova-volume running, but why is nova-api service not starting and complaining about port 8774 being in use when it's not?
