Re: [Rdo-list] [rhos-list] Openstack Grizzly upgrade to Havana

Hi Diogo, > dansmith or larsk may be able to assist. Moving this thread to rdo-list > though, since it is RDO related I don't think that there are any targeted docs up anywhere yet. However, I've been testing it myself to try to make sure we know what the best plan of action is. I have a tool up that I use for testing this, and the scenario files are fairly readable. This is the easiest and most straightforward way to go: https://github.com/kk7ds/test_rdo_upgrade/blob/master/scenarios/grizzly2h... That has stuff in it for testing the before/after cases which you probably don't want to do, but the steps are basically the same. Shutdown all the services, upgrade the packages on all the nodes, then run the database upgrades, and then start everything back up. Note that the scenario above includes a re-run of packstack, but this is not really necessary. To do the database upgrades, each service has a "manage" tool that does low-level database management, so for nova it is: nova-manage db sync This tool only needs to be run once per service and the order of services doesn't matter. Make sense? I will try to get my notes up on a public wiki page somewhere so that this is available someplace other than just this email thread. --Dan
