We have a self-hosted cluster on Kubernetes (EKS) with 1 master node and 2 master-data nodes. To get the performance, we have used NVMe instances. But if both the data node dies, the cluster gets corrupt and we have a loss of data.
However, we can use
EBS volume to prevent data loss and prevent the cluster from getting corrupt.
Is there a way to use EBS attached node only in the time of disaster?
