2016-06-29Dump and restore galera db during major upgradesMichele Baldessari1-0/+44
When the overcloud is upgraded we do a yum update of the packages. This step might introduce a newer galera version. In such a situation we need to dump the db and restore it. The high-level workflow should be the following: 1) During the main upgrade step, before shutting down the cluster we need to dump the db 2) We upgrade the packages 3) We briefly start mysql on a single node while making sure that /root/.my.cnf is briefly moved out of the way (because it contains a password) and import the data. After the import we shutdown this mysql instance 4) We let the cluster start up normally The above steps will take place in the following scenarios. Given a locally installed mariadb version X.Y.Z and release R, we will dump and restore the DB under the following conditions: A) MySqlMajorUpgrade template parameter is set to 'auto' and the upgraded package differs in X, Y *or* Z. We basically don't dump automatically if the release field changes. B) MySqlMajorUpgrade template parameter is set to 'yes' When MySqlMajorUpgrade is set to 'no', no dumping will be performed. Note that this will give a non functional upgrade if a major mariadb upgrade is taking place.

2016-04-13Make sure openstack services are dependent on openstack-coreJiri Stransky1-0/+36
Previously ceilometer-notification, aodh-listener and sahara-engine didn't have constraints that would anchor them under openstack-core dummy resource. Such constraints are added now. (sahara-engine starting after sahara-api, aodh-listener after aodh-evaluator, and ceilometer-notification after openstack-core.) Openstack-core -> heat-api constraint has been removed because heat-api depends on ceilometer-notification, so there's a transitive dependency on openstack-core already.

2016-03-03Function library for major upgradesJiri Stransky1-0/+14
This commit introduces a bash file to be sourced into major upgrade scripts. Into this file we can put specific pieces of migration logic in the form of bash functions, which can then be called from the upgrade scripts. Change-Id: Ibf7aa84d3880e9218c488dec9d707300e1784744
