Expand capacity RustFS on K8s

[casperair77-tech]

Currently, I'm building Rustfs using K8S with 4 nodes and 4 PVCs/1 pod.

How would I expand the pool capacity on this cluster if I add 4 more nodes?

And currently, I'm using a storage class created and managed by DirectPV.

The answer is similar to what explained in #2466 (comment). Basically you add a new pool with a new set of data drives to the ...VOLUMES environment variable along with the existing data pool. In other words, we cannot make any changes to the existing data pool. Only way is to add a new pool even when adding drives on the same nodes.
