Description Liang Xia 2016-10-20 11:41:53 UTC

Description of problem:
A cluster with master in zone1, node in zone2 (in the same region).
Volume provision failed when using StorageClass with region set to zone2.
The error show:
Failed to provision volume with StorageClass "sc1-kjzgt": kubernetes does not manage zone "us-central1-b"

Version-Release number of selected component (if applicable):
openshift v3.4.0.13
kubernetes v1.4.0+776c994
etcd 3.1.0-alpha.1

How reproducible:
Always

Steps to Reproduce:
1.Set up cluster with 1 master and 2 nodes, 1 master and 1 node in zone1, the other node in zone2.
2.Config master and all node, and restart the service.
# cat /etc/gce/gce.conf 
[global]
multizone=true

# vi /etc/origin/master/master-config.yaml
  apiServerArguments:
    cloud-provider:
    - "gce"
    cloud-config:
    - "/etc/gce/gce.conf"
  controllerArguments:
    cloud-provider:
    - "gce"
    cloud-config:
    - "/etc/gce/gce.conf"

# vi /etc/origin/node/node-config.yaml
kubeletArguments:
  cloud-provider:
  - 'gce'
  cloud-config:
  - '/etc/gce/gce.conf'

3.Create StorageClass with region set to zone2.
4.Create PVC with above StorageClass.
5.Check PV/PVC status.

Actual results:
No PV/volume provisioned.
PVC still pending.

Expected results:
PVC should bound to provisoned PV.

Tried again today, can not reproduce it(might be caused by some mis-config yesterday).

This can be closed as not a bug now.
