Description krishnaram Karthick 2018-03-08 07:02:45 UTC 
Description of problem:
When volume metrics data is collected on a glusterfs mountpoint, data collection works as expected and the change in data is captured without any issues. However, when the pod is deleted, the data is not deleted from the pod even after the refresh interval of 6 hours. 


Version-Release number of selected component (if applicable):
oc version
oc v3.9.2
kubernetes v1.9.1+a0ce1bc657
features: Basic-Auth GSSAPI Kerberos SPNEGO

Server https://dhcp46-106.lab.eng.blr.redhat.com:8443
openshift v3.9.2
kubernetes v1.9.1+a0ce1bc657

How reproducible:
Always

Steps to Reproduce:
1. create an app pod with glusterfs mountpoint
2. check whether volume metrics details are collected in prometheus
3. delete the app pod and verify if prometheus doesn't show the information about the volume anymore.

Actual results:
details about the pod is not deleted frpm volume metrics

Expected results:
details anbout the pod should get deleted
