elasticsearch - 从s3存储库还原时快照不存在错误

Question

我刚刚在s3存储库上创建了一个小索引的快照。现在，我正在尝试还原它，它说找不到快照。
我创建的快照来自elasticearch 2.3，我正尝试在Elasticsearch 5.1.1上恢复。我没有意识到某些兼容性问题吗？

另外，在ES 2.3上还原相同快照时，我没有收到错误消息
我使用GET / _snapshot / elasticsearch / _all api检查快照是否存在。得到了以下回应:

      "snapshot": "backup.backupname.17-01-31-1024",
      "version_id": 2030099,
      "version": "2.3.0",

    }

Answer 1

从日志中，我看到:

/_snapshot/elasticsearch/backupname.17-01-31-1024/_restore

您确定快照名称为elasticsearch:backupname.17-01-31-1024吗？

您可以检查

GET /_snapshot/elasticsearch/_all

如果快照存在，请输出快照状态。如果不成功，则表示快照未正确完成。

更新:在我看来，您受到类似的错误https://discuss.elastic.co/t/elasticsearch5-restore-snapshot-from-2-4/66488的影响

好了，基本的解决方法是将其还原到2.3版中，然后关闭群集并从5版开始启动该群集，因为此时索引将被升级，或者等待错误修正。

尽管我不确定ES 5是否可以直接从v2.3恢复，因为介于v2.4之间。
