我有一个 Elasticsearch 在 GKE 集群上作为 ECK 运行，用于生产目的，为了提高其性能，我正在考虑将永久性磁盘类型更改为 SSD。我遇到的解决方案需要在 GCE 中创建磁盘快照，然后使用存储在快照中的数据创建另一个 SSD 磁盘。我仍然担心它是否仍然存在数据丢失的风险，如果我创建另一个磁盘，我的弹性磁盘是否能够匹配它，因为它是有状态的。
I have an elasticsearch running as a ECK on a GKE cluster for production purposes and in order to increase its performance I'm thinking of changing the persistent disk type to ssd. I came accross solutions that incite the need to create a snapshot of the disk in GCE and then create another ssd disk with the data stored in the snapshot. I'm still concerned whether it still has a risk of data loss and if I create another disk will my elastic be able to match it or not as it is statefulset.

由于这是生产部署，我建议执行以下操作：
一旦这个新部署经过全面测试，您就可以切换流量。
Since this is a production deployment I would advise to do as follows:
Once this new deployment has been fully tested you can switch over the traffic.
