Troubleshooting background

To troubleshoot Elasticsearch log “The specified location should start with a repository path specified by” it’s important to know common problems related to Elasticsearch concepts: repositories, repository-azure. See below-detailed explanations complete with common problems, examples and useful tips.

Repositories/Repository in Elasticsearch

What it is

An Elasticsearch snapshot provides a backup mechanism that takes the current state and data in the cluster and saves it to a repository (read the Glossary term Snapshot for more information). The backup process requires a repository to be created first. The repository needs to be registered using the _snapshot endpoint, and multiple repositories per cluster can be created. The following repository types are supported. 

Repository Types:
Repository TypeConfiguration Type
Shared file systemType: “fs”
S3Type : “s3”
HDFSType :“hdfs”
AzureType: “azure”
Google Cloud StorageType : “gcs”
Examples

To register a repository of type fs:

PUT _snapshot/my_repo_01
{
"type": "fs",
"settings": {
"location": "/mnt/my_repo_dir"
  }
}
Notes and common problems
  • S3, HDFS , Azure and Google Cloud requires a relevant plugin to be installed before it can be used for a snapshot.
  • The setting, path.repo: /mnt/my_repo_dir needs to be added to elasticsearch.yml on all the nodes in case you are planning to use repo type of file system otherwise it will fail
  • In case of using remote repositories , the network bandwidth and repository storage throughput should be high enough to complete the snapshot operations normally , otherwise you will end up in partial snapshots.

Log Context

Log ”The specified location should start with a repository path specified by” classname is FsRepository.java
We have extracted the following from Elasticsearch source code to get an in-depth context :

                 logger.warn("The specified location [{}] doesn't start with any "
                    + "repository paths specified by the path.repo setting: [{}] "; location; environment.repoFiles());
                throw new RepositoryException(metadata.name(); "location [" + location
                    + "] doesn't match any of the locations specified by path.repo");
            } else {
                logger.warn("The specified location [{}] should start with a repository path specified by"
                    + " the path.repo setting; but the path.repo setting was not set on this node"; location);
                throw new RepositoryException(metadata.name(); "location [" + location
                    + "] doesn't match any of the locations specified by path.repo because this setting is empty");
            }
        }
