Matthias J. Sax updated KAFKA-9371:
-----------------------------------
Component/s: (was: streams)
> Disk space is not released after Kafka clears data due to retention settings
> ----------------------------------------------------------------------------
>
> Key: KAFKA-9371
> URL: https://issues.apache.org/jira/browse/KAFKA-9371
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 2.2.0
> Environment: CentOS 7.7
> Reporter: Arda Savran
> Priority: Major
> Labels: kafka
>
> We defined retention time on topics for 15 minutes. It looks like Kafka is
> deleting the messages as configured however the disk space is not restored.
> "df" output shows 30G for kafka-logs instead of the real size which is
> supposed to be 1Gb.
> {{/usr/sbin/lsof | grep deleted }}
> output shows a bunch of files under kafka-logs that are deleted but they are
> still consuming space.
> Is this a known issue? Is there a setting that I can apply to kafka broker
> server?
