Bug 1610678

Summary: [3.9] Looks like fluentd is keeping open deleted journal files that have been rotated
Product: OpenShift Container Platform Reporter: Victor Hernando <vhernand>
Component: LoggingAssignee: Jeff Cantrill <jcantril>
Status: CLOSED ERRATA QA Contact: Anping Li <anli>
Severity: medium Docs Contact:
Priority: unspecified    
Version: 3.9.0CC: aos-bugs, emahoney, grodrigu, jcantril, rmeggins
Target Milestone: ---   
Target Release: 3.9.z   
Hardware: x86_64   
OS: Linux   
Whiteboard:
Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: The underlying library that fluentd uses for reading in journal files did not properly handle rolled over files. Consequence: When a journal file was rolled over, fluentd would hold these files even after it was done reading from them. Fix: Updated code in the underlying fluent-plugin-systemd plugin and updated the version in the fluentd dockerfile. Result: We no longer see fluentd holding rolled over journal files.
