Hello All, Not even sure if I am posting this in the correct place. I was following along with this document [here](http://rancher.com/deploying-an-elasticsearch-cluster-using-rancher-catalog/). And got to the part about using scale to add more data nodes, but when I attempt increase the scale to any number greater than 1 it fails to add the new containers and displays this error in the web page: `Degraded (Failed to allocate instance [234]: Object [instance:234] failed to satisfy predicate [15000] millis)` When I check the container before rancher deletes it and tries again I get `Error (Scheduling failed: io.cattle.platform.allocator.constraint.ContainerLabelAffinityConstraint@4961904c)’ I am wondering if I am doing this wrong? My setup is a follows: Single Rancher Docker install. 1st Machine Specs: Intel® Core™ i5-5200U CPU @ 2.20GHz 12GB DDR3 ram 250 SSD storage device Linux Mint 18 2nd Machine Specs: Dell 710 Server Intel® Xeon® CPU X5690 @ 3.47GHz 144GB DDR3 ram 3TB RAID10 storage Debian 8 Software Install specs across all computers: Rancher v1.1.4 Cattle v0.165.8.4 User Interface v1.1.14 Rancher Compose v0.8.6 Docker version 1.12.3, build 6b644ec Any help would be appreciated and thank you for reading.
