从 s3 存储库恢复时快照不存在错误

Question

我刚刚在 s3 存储库上创建了一个小型索引的快照。现在我试图恢复它，它说找不到快照。我创建的快照来自 elasticearch 2.3，我正在尝试在 elasticsearch 5.1.1 上恢复。是否有一些我不知道的兼容性问题？

此外，我在 ES 2.3 上恢复相同快照时没有收到错误消息我使用 GET /_snapshot/elasticsearch/_all api 检查快照是否存在。得到以下回复：

      "version_id": 2030099,
      "version": "2.3.0",

    }

Answer 1

从日志中我看到：

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

您确定您的快照名称是 elasticsearch:backupname.17-01-31-1024 吗？

您可以查看

GET /_snapshot/elasticsearch/_all

如果快照存在，请输出快照的状态。如果不成功，则快照未正确完成。

更新：在我看来你受到了类似错误的影响 https://discuss.elastic.co/t/elasticsearch5-restore-snapshot-from-2-4/66488

基本的解决方法是在 2.3 版本中恢复它并关闭集群并使用版本 5 启动集群，因为索引将在那时升级，或者等待错误修复。

虽然我不确定 ES 5 是否可以直接从 v2.3 恢复，因为 v2.4 介于两者之间。
