Block Storage - Legacy Hardware

I have docker swarm set up on the following servers:


I configured docker to use the rex-ray volume plugin for DigitalOcean block storage.

The plugin sucessfully created a volume called pg-data on In attempting to test the attachment of the volume to another droplet using the swarm services I am getting this error:

"Err": "VolumeDriver.Mount: docker-legacy: Mount: pg_data: failed: POST 422 Droplet can't attach volumes due to a region restriction",

The droplet is the attachment is trying to use.

All of these droplets are on nyc3.

I came across this article:

Note: Currently, the NYC3 region contains both block storage-capable hardware and legacy hardware that does not yet support attaching block storage volumes. If your Droplet is placed on legacy hardware, you will be unable to attach a volume without migrating to a new server.

The best way to ensure that your Droplet will be able to use block storage in NYC3 is to attach a volume during the Droplet creation process. This will guarantee that your Droplet is placed on hardware that supports block storage.

I am wondering if this is the issue? Are we on legacy servers or a mixture? If we have to migrate to have this working what is the impact on our servers since we put a lot of work setting it up? Is there a way we can be moved using our same ip addresses etc....
