Briefly, this error occurs when Elasticsearch is set to not detect or import dangling indices because it’s disabled. Dangling indices are indices that exist on disk but aren’t part of the cluster state. To resolve this, you can enable the detection of dangling indices by setting the ‘gateway.auto_import_dangling_indices’ to true. Alternatively, you can manually import the dangling indices or delete them if they are not needed. Always ensure to backup your data before making such changes to prevent data loss.

Log Context
Log ” is disabled; dangling indices will not be detected or imported” classname is DanglingIndicesState.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :
this.isAutoImportDanglingIndicesEnabled = AUTO_IMPORT_DANGLING_INDICES_SETTING.get(clusterService.getSettings());
if (this.isAutoImportDanglingIndicesEnabled) {
clusterService.addListener(this);
} else {
logger.warn(AUTO_IMPORT_DANGLING_INDICES_SETTING.getKey() + " is disabled; dangling indices will not be detected or imported");
}
}
boolean isAutoImportDanglingIndicesEnabled() {
return this.isAutoImportDanglingIndicesEnabled;
