Essex to Folsom upgrade notes

Setting upgrade expectations right: off-line upgrade with manual intervention!

Here are upgrade notes for upgrading simplest possible 2012.1.3 (Essex) setup (all-in-one minimal Nova+Glance+Keystone setup) to Folsom (now available in epel6)

If you want to stay on Essex use openstack-essex repo

service openstack-glance-registry stop
service openstack-nova-compute stop

service openstack-nova-api stop
  • If on a RHEL based system, manually update Django
rpm -e --nodeps Django
yum install Django14
  • update RPMs
yum update openstack\* python\*client
  • If using nova volumes, update tgtd config like:
