Answer
etcd stores cluster state; corruption makes the cluster unusable.
Quick Answer
etcd is the distributed key-value store that holds all cluster state — every object, every Pod spec, every config, every secret. It's the only stateful part of the control plane. If etcd goes down, the cluster can't accept new operations (though running workloads continue). Regular etcd backups are non-negotiable in production.
