Description Liang Xia 2016-04-06 06:57:23 UTC

Description of problem:
Create PVC, then create PV takes long time to bind.
As the number of PVC/PV increases, the time get longer.

In the testing, 5~15 PVC and 5~15 PV,
generally take 5~8 minutes to get bound.

While create PV first, then create PVC,
generally take less than 1 second to get bound.

Version-Release number of selected component (if applicable):
openshift v1.1.6-12-ge74de69
kubernetes v1.2.0-36-g4a3f9c5
etcd 2.2.5


How reproducible:
Always

Steps to Reproduce:
1.Create several PVCs.
2.Create several PVs.
3.Check PV/PVC status.

Actual results:
PVC took really long time to get bound.

Expected results:
PVC should get bound within a short time.

In Kubernetes 1.2 the default sync interval of binder controller is  minutes. In Kubernetes it went down to 15 seconds, so it should be definitely better there. Appropriate fix is already merged into Kubernetes, waiting for rebase in OpenShift.

Sorry, this has been fixed a long time ago. Default binder sync is 15 seconds since 3.3.
