Can't mount nfs since updated Synology NAS to DSM 7.2

    I decided to update my Synology NAS from DSM 7.1 to DSM 7.2 today and now my auto mount fails with a timeout and I can't work out why. It still works perfectly with my OSMC media box which uses autofs.

    LibreElec: 11.0.1

    Synology: DSM 7.2-64570 Update 1

    my .mount file in system.d looks like this:

    [Mount]

    # The share we want mount

    What=192.168.0.10:/volume1/Multimedia

    # Where we want mount this share

    Where=/storage/multimedia

    # Any options you usually use with the "-o" parameter in the mount command

    Options=

    # filesystem type

    Type=nfs

    [Install]

    WantedBy=multi-user.target

    and when I run it I get

    systemctl start storage-multimedia.mount

    systemctl status storage-multimedia.mount

    × storage-multimedia.mount - test nfs mount script

    Loaded: loaded (/storage/.config/system.d/storage-multimedia.mount; enabled; preset: disabled)

    Active: failed (Result: timeout) since Sat 2023-07-22 13:21:10 BST; 3min 20s ago

    Where: /storage/multimedia

    What: 192.168.0.10:/volume1/Multimedia

    CPU: 3ms

    I am happy to swap to SMB instead but when I try setting it up using the guide I get :

    Options=username=kodi,password=<password>,rw,ver=2.1

    Type=cifs

    Jul 22 13:30:58 MEDIACENTRE mount[1282]: mount: mounting 192.168.0.10:/volume1/Multimedia on /storage/multimedia failed: Invalid argument

    As I say it continues to work fine with autofs on osmc

    My Synology settings for NFS are:


    Does anyone have any ideas of anything else I can check?

    Thanks

    Hi there,

    have you tried to manually mount the NFS export on your libreElec via console?

    Please provide the following output, as it's more helpful to determine what happened.

    Bash
    mount -v -t nfs -o vers=3 <server IP>/<nfs export name> /<mount dir on libreelec>

rpcinfo -s <server IP>
rpcinfo -m <server IP>


    I honestly have no experience with Synology NAS - but one thing that catches my eye, you limited your server side (NAS) NFS version to 2 and 3.

    You should consider at least allow NFSv4 in addtion. Also I would deactivate NFSv2, if you don't have to support it.

    (See their documentation, at least what a quick ddg search got me: https://kb.synology.com/en-global/DSM/…s_nfs?version=7)

    Cheers Joker, Just adding ver=3 to the options in the mount file fixed it! I tried so many options for cifs but not nfs

    Options=ver=3

    I guess it must try to use an older nfs protocol to connect by default and they have removed support for that now.

    Thanks for pushing me in the right direction.
