What PVC do you have attached to Mongo? If it is RWO and you're using the "rolling" strategy that will not work as the PVC can be used only by one pod. In that case you have to switch it to Recreate strategy.

Hi Michal,

Yes, the PVC y RWO type. What do you mean with rolling/recreate strategy? Is here any documentation about it? I simply have deployed the example proyect, without any change.

Thanks for your help!

This is the PVC information:

oc get pvc
NAME      STATUS    VOLUME         CAPACITY   ACCESSMODES   AGE
mongodb   Bound     pv-aws-hf25u   1Gi        RWO           1d

This is the log of a failed deploy:

--> Scaling mongodb-1 to 1
--> Waiting up to 10m0s for pods in deployment mongodb-1 to become ready
error: update acceptor rejected mongodb-1: pods for deployment "mongodb-1" took longer than 600 seconds to become ready

The PVC is only trying to be used by this deploy, so it is not being used to another pod. This configuration was generated with the template "nodejs-mongodb-example". 

And here the yaml of the last failed deploy:

Do you need more information?

Is this problem related with the alert in the Openshift Web Console?
"Investigating - We notice that there is an issue when create persistent volumes"

I think this is a duplicate of: https://bugzilla.redhat.com/show_bug.cgi?id=1392650

(or at least the symptoms are looking the same).

Marking this bug a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1392650 as that bug has a lot of debugging information captured.
