E.3. Secvenţial (nod după nod)

În acest scenariu fiecare nod este scos din cluster, actualizat şi apoi adus înapoi online până ce toate nodurile rulează pe cea mai recentă versiune.


Această metodă este în prezent nefuncţională între Pacemaker 0.6.x şi 1.0.x
Measures have been put into place to ensure rolling upgrades always work for versions after 1.0.0. Please try one of the other upgrade strategies. Detach/Reattach is a particularly good option for most people.

E.3.1. Procedură

On each node: . Shutdown the cluster stack (Heartbeat or Corosync) . Upgrade the Pacemaker software. This may also include upgrading the cluster stack and/or the underlying operating system. .. On the first node, check the configuration manually or with the crm_verify tool if available. .. Start the cluster stack.
+ This must be the same type of cluster stack (Corosync or Heartbeat) that the rest of the cluster is using. Upgrading Corosync/Heartbeat may also be possible, please consult the documentation for those projects to see if the two versions will be compatible.
+ .. Repeat for each node in the cluster.
