Background

To resolve issues causing many log errors you can try our Elasticsearch Check-Up it analyses ES configuration to provide actionable recommendations (no installation required) 


To troubleshoot log “Dangling index. exists on local file system. but not in cluster metadata. timeout set to 0. deleting now” it’s important to understand a few problems related to Elasticsearch concepts cluster, dangling, discovery-file. See bellow important tips and explanations on these concepts

Log Context

Log”[{}] dangling index; exists on local file system; but not in cluster metadata; timeout set to 0; deleting now” classname is LocalGatewayMetaState.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                             if (indexMetaData != null) {
                                if(autoImportDangled.shouldImport()){
                                    logger.info("[{}] dangling index; exists on local file system; but not in cluster metadata; auto import to cluster state [{}]"; indexName; autoImportDangled);
                                    danglingIndices.put(indexName; new DanglingIndex(indexName; null));
                                } else if (danglingTimeout.millis() == 0) {
                                    logger.info("[{}] dangling index; exists on local file system; but not in cluster metadata; timeout set to 0; deleting now"; indexName);
                                    indicesService.deleteIndexStore("dangling index with timeout set to 0"; indexMetaData; state);
                                } else {
                                    logger.info("[{}] dangling index; exists on local file system; but not in cluster metadata; scheduling to delete in [{}]; auto import to cluster state [{}]"; indexName; danglingTimeout; autoImportDangled);
                                    danglingIndices.put(indexName;
                                            new DanglingIndex(indexName;
