> In case you have shared S3 datastore, and you haven't updated the
> repository-* files in the META/ folder after you add/remove some instances,
> you'll notice an error like this in the logs:
>
> {code:java}
> 10.12.2018 04:01:23.535 *ERROR* [sling-oak-observation-51349]
> org.apache.jackrabbit.oak.plugins.blob.MarkSweepGarbageCollector Not all
> repositories have marked references available :
> [61b97331-58a8-434b-bb49-a43726b569bf]
> {code}
> Unfortunately, this error isn't reported back, so it appears DSGC has
> succeeded.
>
> The logs state (for example):
>
> {code:java}
> 10.12.2018 04:01:23.535 *INFO* [sling-oak-observation-51349]
> org.apache.jackrabbit.oak.plugins.blob.MarkSweepGarbageCollector Blob garbage
> collection completed in 20.25 s (20247 ms). Number of blobs deleted [0] with
> max modification time of [2018-12-09 04:01:03.288]
> {code}
> And the BlobGarbageCollection JMX bean reports success as well.
> This is not wanted behaviour as the DSGC run has actually failed.
> An IOException is thrown in
> [https://github.com/apache/jackrabbit-oak/blob/trunk/oak-blob-plugins/src/main/java/org/apache/jackrabbit/oak/plugins/blob/MarkSweepGarbageCollector.java#L815,]
> but it is caught and not re-thrown at
> [https://github.com/apache/jackrabbit-oak/blob/trunk/oak-blob-plugins/src/main/java/org/apache/jackrabbit/oak/plugins/blob/MarkSweepGarbageCollector.java#L462]
> I think this exception should be re-thrown there causing it to be caught at
> [https://github.com/apache/jackrabbit-oak/blob/trunk/oak-blob-plugins/src/main/java/org/apache/jackrabbit/oak/plugins/blob/MarkSweepGarbageCollector.java#L362]
> resulting in the correct behaviour.
