inventory file used for logging deployment to let this bz repro

Description of problem:
Created according to discussions in https://bugzilla.redhat.com/show_bug.cgi?id=1426137
Roll over log entries are visible when openshift_logging_fluentd_journal_read_from_head is default to empty on journald log driver envs.
Issue did not repro when openshift_logging_fluentd_journal_read_from_head is not specified.
    
Version-Release number of selected component (if applicable):
openshift-ansible-3.5.28-1.git.0.103513e.el7.noarch

How reproducible:
Always

Steps to Reproduce:
1.Deploy logging 3.5.0 with ansible scripts ,including this parameter:
openshift_logging_fluentd_use_journal = true
and make sure parameter "openshift_logging_fluentd_journal_read_from_head "is unspecified in the inventory file
2.Tail ES log for namespaces that was created prior to EFK deployments
3.Log in kibana

Actual results:
2.Index mappings was created in ES for namespaces that was created prior to EFK deployments
3.Roll over logs are displayed

Expected results:
2.Index mappings should not be created in ES for namespaces that was created prior to EFK deployments
3.Roll over logs (and indices) should not exist

Additional info:
inventory file used for logging deployment was attached

Is this a problem of seeing duplicate logs in Kibana?  Or are you not expecting to see old logs?

Comment 3 Xia Zhao 2017-07-13 08:33:58 UTC 
According to https://bugzilla.redhat.com/show_bug.cgi?id=1426137#c22, I'm considering on adjusting the test scope here, and the situation when openshift_logging_fluentd_journal_read_from_head is not set (default to false) is test passed with 3.6 installer, please feel free to transfer back to ON_QA for closure. Thanks!
