Every change in control-plane nodes when a cloud provider doesn't support disk resizing can result in etcd data being lost/corrupted. Adding a separate disk for the etcd data would prevent those kinds of disasters and give us more freedom when altering the Terraform control-plane nodes. By default, the etcd database size limit is 2GB ref So even a small disk with hardcoded value would fit into this scenario.

Similar tasks: #641

Exit criteria

  • Kubernetes control-plane nodes have a separate disk for storing etcd database

Theoretically, this could be a small SSD disk.
This should leave us with an option to use a cheaper HDD for the OS.
