I just created a snapshot of a small index on an s3 repository. Now I am trying to restore it and it says that the snapshot was not found. The snapshot i created was from elasticearch 2.3 and i am trying to restore on elasticsearch 5.1.1. Is there some compatibility issue that i am unaware of?

Also, i do not get the error on restoring the same snapshot on ES 2.3 I checked if the snapshot exists using the GET /_snapshot/elasticsearch/_all api. Got the following response:

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

从我看到的日志中：

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

你确定你的快照名称是elasticsearch:backupname.17-01-31-1024？

你可以检查

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，您受到类似错误的影响https://discuss.elastic.co/t/elasticsearch5-restore-snapshot-from-2-4/66488

那么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 5 版本启动集群，因为索引将被升级，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。
