Description Luis Pabón 2016-07-18 21:32:15 UTC

Description of problem:
If a new upgraded container is available, the administrator can type:

$ oc deploy heketi --latest

To deploy the latest Heketi container.  The problem is that using a "Rolling"
strategy will not deploy the new Heketi, since the old one still has access the to the database.  Need to change the strategy to "Recreate" so that the previous container is shut down first before deploying the new one.

Comment 2 Luis Pabón 2016-07-19 00:34:07 UTC

This is a blocker because we cannot upgrade Heketi or GlusterFS without the correct setting.

This affects both the Heketi and GlusterFS templates.

I believe this is not expected behaviour. @Humble , could you please give a look.

@Neha, the 'recreate' strategy should stop the pod and deploy the new one without issues. We have analysed the root cause and the solution for this issue which will be updated soon in this bugzilla.
