Description Liang Xia 2017-10-12 07:20:12 UTC 
Description of problem:
Create pvc first, then create pv, binding can take up to 400+ seconds.
While compared with creating pv first, binding finished in a second.

This is really bad user experience.


Version-Release number of selected component (if applicable):
openshift v3.7.0-0.143.2
kubernetes v1.7.0+80709908fd
etcd 3.2.1


How reproducible:
Always


Steps to Reproduce:
1. Create a pvc, then create a pv, check binding.
2. Create a pv, then create a pvc, check binding.


Actual results:
Binding take up to 400+ seconds when pvc is created first.
While binding finished in a seconds when pv is create first.


Expected results:
Binding should be done in a reasonable time in either way.

Seems like nobody ported https://bugzilla.redhat.com/show_bug.cgi?id=1470009 back to 3.7.

Comment 6 Liang Xia 2017-10-24 07:04:02 UTC 
Tested again on below version,
# openshift version
openshift v3.7.0-0.176.0
kubernetes v1.7.6+a08f5eeb62
etcd 3.2.8

binding is much faster now, pvc/pv got bound in 30 seconds, generally 10 seconds or so.
