Fuel for OpenStack

Applying patches on deployed nodes

Asked by Claude Durocher

Document https://docs.mirantis.com/openstack/fuel/fuel-6.1/maintenance-updates.html states that after applying updates, all non-HA OpenStack services on compute and controller nodes should be restarted.

Is it possible to have a list of those services?

Greetings Claude,

this very depends on your configuration. If you have installed Murano, Sahara and other additional services, they must be restarted too. In the standard list, all services not under pacemaker (which includes Ceilometer and Heat in 6.1+) should be restarted. Get them by these two commands:

services=$(curl http://git.openstack.org/cgit/open\
stack/governance/plain/reference/projects.yaml | \
  egrep -v 'Security|Documentation|Infrastructure' | \
  perl -n -e'/^(\w+):$/ && print "openstack-",lc $1,".*\$|",lc $1,".*\$|"')

initctl list | grep -oE $services | grep start

Best regards,
Fabrizio
