Unexpected behavior with named Docker NFS volumes in a Swarm cluster - docker

Question

I'm new to Docker Swarm and I'm managing all config via Ansible. I have a four-node Swarm cluster with the following members
manager (also the NFS exporter for volumes shared across the cluster)
cluster0
cluster1
cluster2
cluster[0-2] are workers in the swarm.
I'm configuring a service which makes use of a named volume media, which is an NFS export from manager. The service is constrained to the worker nodes. Once a service is deployed that makes use of this volume, I'd expect to see the following output of docker volume inspect media from any of the worker nodes with the replicated service:
user#cluster1:~ $ docker volume inspect media
[
{
"CreatedAt": "2021-01-27T12:23:55-08:00",
"Driver": "local",
"Labels": null,
"Mountpoint": "/var/lib/docker/volumes/media/_data",
"Name": "media",
"Options": {
"device": ":/path/media",
"o": "addr=manager.domain.com,rw",
"type": "nfs"
},
"Scope": "local"
}
]
and indeed when I docker volume inspect media from the swarm manager, I see:
user#manager:~$ docker volume inspect media
[
{
"CreatedAt": "2021-11-22T07:58:55-08:00",
"Driver": "local",
"Labels": null,
"Mountpoint": "/var/lib/docker/volumes/media/_data",
"Name": "media",
"Options": {
"device": ":/path/media",
"o": "addr=manager.domain.com,rw",
"type": "nfs"
},
"Scope": "local"
}
]
However, this is the output I see from the nodes with the replicated service:
user#cluster1:~ $ docker volume inspect media
[
{
"CreatedAt": "2021-11-22T07:59:02-08:00",
"Driver": "local",
"Labels": null,
"Mountpoint": "/var/lib/docker/volumes/media/_data",
"Name": "media",
"Options": null,
"Scope": "local"
}
]
As a result, I'm unable to access the NFS-exported files. I'm not entirely sure how to troubleshoot. Is this a limitation of Swarm and if so, how are others working around this issue? If not, what am I missing?
