Resizing on DigitalOcean

[alekseyp]

When I try to update size via spec:

spec:
  volume:
    size: 5Gi

I'm getting next error:

time="2020-03-29T01:31:44Z" level=warning msg="volume \"pvc-ac20846d-7160-438d-884d-2ea63372a142\" is incompatible with all available resizing providers" cluster-name=default/acid-minimal-cluster pkg=cluster

Looks like operator only supports EBS?

I was able to resize pvc manually by editing pvc config kubectl edit pvc pgdata-acid-minimal-cluster-3 directly and it worked like a charm:

@alekseyp Yes, currently only EBS volumes can be handled / resized by the Operator - which is why I suggested switching to using CSI to manage volumes and their resizing: #460

[frittentheke]

@alekseyp there is a new PR implementing resizing via PVC change: #958

This should (!) work on Digital Ocean as well.

I think we can close this one now with the native resizing available. Thanks @alekseyp for raising.
