Resolution resolution
This issue might occur if you had a previous instance using the datastore, which was destroyed and a new instance created to use the datastore.
The issue can be resolved after removing repository id registered in the datastore. Blob store GC then should complete successfully.
Step-by-step guide:
1)Go to datastore path < aem-install-folder> /crx-quickstart/repository/datastore and search for repository id e0fb2a15-d5d5-4013-9607-0fb89cf87c94 (it should be same as the one mentioned in error.log ERROR* [ sling-oak-observation-19] org.apache.jackrabbit.oak.plugins.blob.MarkSweepGarbageCollector Not all repositories have marked
references available : [ e0fb2a15-d5d5-4013-9607-0fb89cf87c94] ), you will have a reference file with this name, just delete that reference file (repeat these steps if there are multiple files).
2)Run the GC again and check if it resolves the issue.
