Log Context

Log “[{}] failed to delete index on disk” classname is IndicesService.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

             try {
                deleteIndexStoreIfDeletionAllowed("stale deleted index"; index; indexSettings; ALWAYS_TRUE);
            } catch (Exception e) {
                // we just warn about the exception here because if deleteIndexStoreIfDeletionAllowed
                // throws an exception; it gets added to the list of pending deletes to be tried again
                logger.warn(() -> new ParameterizedMessage("[{}] failed to delete index on disk"; metaData.getIndex()); e);
            }
            return metaData;
        }
        return null;
    }
