Before you begin reading this guide, we recommend you run Elasticsearch Error Check-Up which can resolve issues that cause many errors.

This guide will help you check for common problems that cause the log ” Failed to delete index on disk ” to appear. It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: delete, index and indices.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).

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;
    }
