Known issues

edit

  • Snapshot and restore: If an index is deleted while the cluster is concurrently taking more than one snapshot then there is a risk that one of the snapshots may never complete and also that some shard data may be lost from the repository, causing future restore operations to fail. To mitigate this problem, prevent concurrent snapshot operations by setting snapshot.max_concurrent_operations: 1.

    This issue is fixed in Elasticsearch versions 7.13.1 and later. For more details, see #73456.
