Rancher 2.6 and Digital Ocean volume


I need to advise. I have created cluster for my application and I need add storage to my postgresql deployment. I created volume in digital ocean named “db”.

In my host is volume mounted in /mnt/db_volume

Now I need add volume to my deployment. I click Edit config → Storage → NFS.

After save container is still unhealthy. No logs in deployment log.

Do I something bad?
