[Resolved] Removed Machine from Cattle and cannot re-add it

Rancher 1.x
1

I deleted a host and tried to re-add it but it will not show up. I removed all images from the host and all running containers.

I then re-did the command to add the host (from Step 5 on the Add host screen) but it will not show up in the Hosts pages with the others.

I checked the running containers on the host I am trying to add and the agent is running properly:

CONTAINER ID        IMAGE                  COMMAND                  CREATED             STATUS                      PORTS               NAMES

Remove the agent containers, rm -rf /var/lib/rancher/state (on the host), then run the registration command again. The state dir contains a UUID for the host and the server is ignoring the registration because it’s coming from “the same” host that it knows was deleted.

Awesome that worked.

Thanks.
