I have a 3 node cluster. I want when 1 node down then all container switch to another node in the cluster . that’s why need remote storage I think. Could u give me any better idea or solution? I am on RND about it.

Right, you can do something like that if using the CEPH storage backend, in that mode, when a node goes down the container goes into BROKEN state but can still be moved to another node and then started back up there.

This moving process isn’t automatic but you can do that easily enough with an API client.
We don’t want such things to be automatic as people do sometimes temporarily take a node down and having all containers get reshuffled when this happens would be a problem.
