Rancher 1.x

I add host to Rancher after updated to rancher v1.1.0 .
The rancher agent is running on node host ,but there is no host on rancher UI

Can you look at the logs in rancher/agent on the host?

I remove one of two -v options on run command, Now can add host ,but restart the host ,all hosts and stacks lose. (run command is docker run -d --restart=always --name=rancher-server -p 8080:8080 -v /var/lib/rancher:/var/lib/rancher rancher/server)
