Good day,
I had installed rancher cluster several times before. I was faced with the problem that both /var/lib/docker and /var/lib/rancher get filled up rather quickly so I remade my installation to avoid those folders. /var on my machines only have 7gb and its something i cant change.
Fortunately when setting up a cluster i can tell rancher to store everything on a different folder:
On my rke file i have the option:
prefix_path: “/apps/rancher”
RKE gives me the error:
DEBU[0075] Failed to get /health for host [10.11.209.107]: Get https://10.11.209.107:2379/health: Unable to access the service on 10.11.209.107:2379. The service might be still starting up. Error: ssh: rejected: connect failed (Connection refused)
So I check docker etcd logs cause thats the etcd health check and it keeps giving me the same error while trying to restart:

…
Cause i am using the prefix path there isnt a /var/lib/rancher.
The etcd folder was created under my prefix path but the docker container is trying to reach the wrong folder.
