For example, internal tests showed that caching 5000 ConfigMaps, totaling 50 MB, consumed 81 MB of disk space. For a conservative, high-level estimate, you can plan for the available disk space on each relevant node to be at least **twice the size of your etcd snapshot**. For most production environments, ensuring a few extra gigabytes of storage are available on the relevant nodes is a safe starting point.
Please note this space counts against [ephemeral storage](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/#setting-requests-and-limits-for-local-ephemeral-storage) requests and limits you might have set for your Rancher container via the `resource` value in the Helm chart. Make sure those settings provide for abundant available space.
If you see the error `database or disk is full (13)` in the pod logs, this is a symptom that more space needs to be allocated.
SQLite-backed caching persists copies of any cached Kubernetes objects to disk. See [Encrypting SQLite-backed Caching](#encrypting-sqlite-backed-caches) if this is a security concern.
