**Describe the feature** : I created a backup repository to report an error。
**Elasticsearch version** ( `bin/elasticsearch --version` ): 6.8.6
**JVM version** ( `java -version` ): jdk-13.0.1+9
**OS version** ( `uname -a` if on a Unix-like system): centos 7 X86 64 kernel: 5.5.4-1.el7.elrepo.x86_64
I use the official docker image file “ docker.elastic.co/elasticsearch/elasticsearch-oss:6.8.6 ” in the K8S。
1. I set the "path.repo" to /mnt and mounted the container's /mnt path to the local /mnt directory,
2. While I mounted the NFS Shared storage to the local /mnt directory.
3. I mount the same shared filesystem to the same location on all master and data nodes.
Here's what I did:
curl -H 'Content-Type: application/json' -XPUT https://elasticsearch.root.com/_snapshot/2020-03-22 -d '
{
"type": "fs",
"settings": {
"location": "/mnt/2020-03-22",
"max_snapshot_bytes_per_sec": "50mb",
"max_restore_bytes_per_sec": "50mb",
"compress":true
}
}'
{"error":{"root_cause":[{"type":"repository_verification_exception","reason":"[2020-03-22] cannot delete test data at "}],"type":"repository_verification_exception","reason":"[2020-03-22] cannot delete test data at ","caused_by":{"type":"i_o_exception","reason":"could not remove the following files (in the order of attempts):\n /mnt/2020-03-22/tests-bROfi9MOQOy8Xr4RifViWg: java.nio.file.DirectoryNotEmptyException: /mnt/2020-03-22/tests-bROfi9MOQOy8Xr4RifViWg\n"}},"status":500}
The application reports an error message:
