I have a NFS server that export a file-system.

showmount -e nfsserver
Export list for nfsserver:
/opt/application/aghas0/docker client1,client2

on the client2 server I have mounted the file-system from the nfsserver and that worked.

nfsserver:/opt/application/aghas0/docker  9.8G   23M  9.2G   1% /opt/application/aghas0/docker

so I tried to create a NFS Docker Volume named nfsvol

docker volume inspect nfsvol
        "CreatedAt": "2019-07-16T16:31:47+02:00",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/nfsvol/_data",
        "Name": "nfsvol",
        "Options": {
            "device": ":/opt/application/aghas0/docker",
            "o": "addr=nfsserver_Ip,rw",
            "type": "nfs"
        "Scope": "local"

but when I try to mount this volume to a container I get the error bellow:

docker run -it -v nfsvol:/mnt alpine sh
docker: Error response from daemon: error while mounting volume with options: type='nfs' device=':/opt/application/aghas0/docker' o='addr=,rw': input/output error.

I am using NFS4. I don't know if there is a specific configuration for this version. Does any one know how to fix this please ?

  • I am getting confused as to what is what. Is it a client, is it a server? – ctrl-alt-delor Jul 17 '19 at 8:40
  • Can you include Dockerfile – ctrl-alt-delor Jul 17 '19 at 8:44
  • I created the docker volume on the client server and started a basic alpine image – zeO_340 Jul 17 '19 at 9:42
  • client server = server that mount the filesystem shared by the nfs server. nfsvol is a docker volume created on the client server – zeO_340 Jul 17 '19 at 12:56
  • yep... that is just semantics, I don't believe that change the problem understanding. I have to rhel server that are client to my nfs server... English isn't my first language so I try my best to be clear... sorry if it wasn't the case for you – zeO_340 Jul 22 '19 at 8:37

Found the problem.

I had to pass as an option the nfs version used, when I create the docker volume,like this :

docker volume create --driver local --opt type=nfs --opt o=addr=nfsserver_IP,rw,vers=4 --opt device=:/opt/application/aghas0/ansible nfsvol

this has solved my problem
