You can move your workload using the volume to region A. |

The workload and replicas are in right region, but the problem si when the volume is attached to a node from another region.

Hello, I have the same issue with data locality in 'best effort' mode not helping. When a pod attaches to a volume located in a different zone than the pod itself, I experience application latencies. I would like the pod to attach to the volume within the same zone. |

Hello,
In our Custer we have multiple nodes from 3 different regions (let's say A, B and C).
Each node has tags with zone name. When I create a volume for region A and mount it to a workload, replicas are made on A region nodes, but the problem is that it become attached to a random server. And most of the time is attached to a node from region B or C. and performance is very poor because bandwidth between region is weak.
Is there a method to explicit attach a volume to some specific nodes in Longhorn, or I miss something?
Thank you!
