Check status:
```
sudo crictl ps -a | grep etcd
sudo crictl logs <id>
```

Maybe a safish restore?:

```
sudo cp /var/lib/etcd/member/snap/db ./test.db
sudo mv /var/lib/etcd{,.bak}
sudo bash
systemctl daemon-reload
systemctl stop crio
systemctl stop kubelet
ETCDCTL_API=3 etcdctl snapshot restore ./test.db  --skip-hash-check=true --data-dir=/var/lib/etcd/
systemctl start crio
systemctl start kubelet
```
