Da Caracal a Epoxy
Procedura indicativa
A grandi linee la procedura sara':
- -
- Sul secondo controller i servizi sono attivi con versione C -
- Si spengono due dei tre db percona
- Si configura HAproxy in modo da far puntare al secondo controller
- Si spengono tutti i servizi sul primo controller
- Si aggiornano i pacchetti a E e si aggiiornano i file di configurazione
- sul primo controller (
- senza fare partire i servizi )
- Si configura e si fa partire un servizio alla volta sul primo controller e si configura HAproxy in modo da far puntare per quel servizio al primo controller
- Si spengono tutti i servizi sul secondo controller e si aggiorna il secondo controller a epoxy, facendo partire i servizi
- Si modifica HAproxy in modo che punti a entrambi i controller
- Si aggiornano i compute node uno alla volta
Sul primo controller: keystone-manage db_sync --expand (il --expand di fatto fa in modo che il Db sia usabile sia per la versione C che per la versione E)
Sul primo controller si avvia keystone
si spegne keystone sul secondo controller
Sul primo controller: keystone-manage db_sync --contract
lo stesso per tutti gli altri servizi
Alla fine si aggiorna il secondo controller e si fanno partire anche li' i servizi
Check preliminari ed installazione release sul controller1
Azioni da fare prima di cominciare con l'installazione della release
Spegnere mysql su due dei tre nodi percona ricordando l'ordine di spegnimento
- Controllare che tutti i servizi Openstack siano spenti (MS no) Migrare online il db placement e nova
Code Block language shell [root@cld-db-test-06 ~]# systemctl stop mysql [root@cld-db-test-05 ~]# systemctl stop mysql- Modificare la classe puppet epoxy dei controller (service.pp) in modo che non faccia partire i servizi
Code Block language shell ATTENZIONE: modificare il file service.pp di puppet perche' non faccia partire i servizi una volta aggiornati. Per questo mettere tutti i servizi in ensure => stopped,
enable
@centos-openstack-caracal=> false, e committare su git- Modificare l'HA in modo che per tutti i servizi punti al controller-02, che ha i servizi a Caracal attivi. Per questo modificare il file in cld-config ed eseguire puppet sui tre haproxy
Code Block language shell title HAProxy # in cld-config.cloud.pd.infn.it cp /etc/puppetlabs/code/environments/production/modules/cloudtest_haproxy/files/servizio_httpd_glance_nova_neutron_cinder_heat_spento01_acceso02.cfg /etc/puppetlabs/code/environments/production/modules/cloudtest_haproxy/files/haproxy_el9.cfg # in cld-haproxy-test-01.pd.infn.it, 02 e 03 puppet agent -t - In entrambi i controller spegnere e disabilitare puppet
#placement va fatto prima di nova

Upgrade all keystone nodes to the next release, and restart them one at a time. During this step, you’ll have a mix of releases operating side by side, both writing to the database. As the next release begins writing to the new schema, database triggers will also migrate the data to the old schema, keeping both data schemas in sync. Run keystone-manage db_sync --contract to remove the old schema and all data migration triggers. When this process completes, the database will no longer be able to support the previous release.

Compute
Mettere in drain un nodo alla volta.
openstack compute service set --disable compute-01.cloud.pd.infn.it nova-compute
openstack compute service list
Per il singolo nodo in drain, migrare le VM con live migration quando possibile (altrimenti si spegne e si migra)
In foreman cambiamo la classe per Epoxy
Giro puppet
In caso di nodi con VM che non possono essere migrate come fare l'update (vedi in passato)
----QUI---
Configurare il controller via puppet
in foreman https://cld-config.cloud.pd.infn.it/hosts/controller-01.cloud.pd.infn.it editare l'host sostituendo l'hostgroup "hosts_all/ControllerNode-Test" con "hosts_all/ControllerNode-Test_Epoxy" ed eseguire puppet nel nodo
