In my limited experimentation I had problems with NFS PVs getting wiped out even though the policy was set to Retain. In fact I ended up in this situation where if I created a file in the NFS volume it was deleted in front of my eyes in a few seconds. Obviously I did something very wrong with the PV. I've found mounting the NFS volume directly into the pod as Seth suggested a lot easier. I also was unable to force a particular PV to be bound to a PVC. They seem to work like a pool and you get what you get. So if you have an existing nfs volume with data you want to mount into a particular pod there might not be a way of doing that with PV's but I would love to be proven wrong by others.
