How to rotate TarJournal in Shared Nothing Clustering

Use Case: Your tar Journal is growing and consuming a lot of space.

Solution: If you are using shared clustered Please refer

For shared nothing clustering you need following configuration (If you want rotation after every 24 Hour) in repository.xml

<Journal class="">
<param name="maxFileSize" value="104857600" />
<param name="maximumAge" value="PT24H" />

Please note that Age specified as duration in ISO 8601 or plain format. Journal files that are older than the configured age are automatically deleted. The default is "P1M", which means files older than one month are deleted.

More detail can be found here

Important Note : If you do above configuration then make sure that other instance in the cluster is not down for more than specified time in "maximumAge", Otherwise cluster will get Out Of sync because of rotation of tarJournal.
