Rancher Restore KO

#1

Hi All,
I’m using Rancher 2.1.6 and I’m encountering an error during restore.
I’m following the manual integrated in this link :

https://rancher.com/docs/rancher/v2.x/en/backups/restorations/ha-restoration/

I obtain the error during the execution of this command : (chapter 4-Restore Database)

**rke etcd snapshot-restore --name .db --config ./rancher-cluster-restore.ym**l

follows you can find the description error:
