Problem mounting Nas (NFS) with systemd

imarco · 14 December 2024 10:07

Hi,
I tried to mount my Qnap Nas using the mount unit with this topic: [root tip] [How To] Use systemd to mount ANY device but i obtain error when i verify the service.

I have 3 disks in the Nas named 2025, data and Multimedia, i choose at random data/2022 (which is a folder of the disk named data).

I did this:

[Unit]
Description=Mount NAS Video share using NFS

[Mount]
What=192.168.1.10/data/2022
Where=/home/marc/qnap/
Type=nfs
Options=_netdev,auto

[Install]
WantedBy=multi-user.target

Then:

marc@marc-pc ~]$ sudo nano /etc/systemd/system/home-marc-qnap.mount

I searched on the forum but i didn't find why it failed.

Thanks.

Not sure why it failed but the usual place for the mount info is

/etc/systemd/system then use a command like

sudo systemctl enable --now Data-Documents.mount

imarco · 14 December 2024 11:10

Not working.

should that not be the address?

I would rather try it “by hand” first - to see whether it works in principle:

sudo mount -t nfs 192.168.1.10:/data/2022 /home/marc/qnap

Only then would I try to translate that to a systemd mount unit.

I’d also not mount the share to somewhere in /home but rather to a dedicated mount point below /
like:
/mnt/my_nfs_share
or just
/my_nfs_share
because you might want to use /mnt at some point for some reason …

obviously you’d have to create that directory first …

Then it may also be necessary to include some option for when the device only supports some particular version of the nfs protocol.

imarco · 14 December 2024 11:44

[marc@marc-pc ~]$ sudo mount -t nfs 192.168.1.10:/data/2022 /home/marc/qnap
[sudo] Mot de passe de marc : 
mount.nfs: access denied by server while mounting 192.168.1.10:/data/2022
[marc@marc-pc ~]$

Indeed, there is a problem…
I’d already activated smb and nfs in my NAS.

Nachlese · 14 December 2024 11:51

Whatever that might mean …
… the server (your qnap) must export the directories that are to be mountable by the clients:

https://wiki.archlinux.org/title/NFS#Server_configuration

I don’t know anything about your qnap - what it is or how to operate/configure it …

linux-aarhus · 14 December 2024 12:30

I think your issue is caused by your attempt to mount a subfolder on your share - which is not possible - it is not exported.

imarco · 14 December 2024 12:33

You mean i should use this
192.168.1.10:/data/
Instead of 192.168.1.10:/data/2022 ?

linux-aarhus · 14 December 2024 12:36

You can only mount the exported path - so if your export is ip.x.y.z:/data this is what you can mont.

There is some caveats using nfsv4 vs nfsv3, see → NFS - ArchWiki

Also see → [root tip] [How To] Share data using NFS

Nachlese · 14 December 2024 12:48

(the above not an active link - highlight/mark it - right click on it - choose open link from context menu …)

… which is essentially the same as what @linux-aarhus said

How you define your exports in your qnap … I don’t know.

imarco · 14 December 2024 12:54

I don’t know too (yet).

I’m wondering if i really understand how it works: i want to access to my disks in my Nas as they were internal; so i have to mount all disks and repeat here 2 times the process to mount the 3 disks (and fourth one day if i add a disk in my Nas)?

Nachlese · 14 December 2024 12:59

first you have to tell your NAS to export either … everything
or
specific directories
so that these can then be accessed via nfs by you (the client)

Your NAS is the server - your machine is the client.

How you tell your NAS what directories it should export / make available for access via NFS … I don’t know.
I don’t have such a thing …

imarco · 14 December 2024 13:11

Ok.
I should have study that before the purchase…

Nachlese · 14 December 2024 13:26

If it has got NFS support - there is a way to configure it via it’s web interface (where you also enabled NFS … somehow)
Perhaps it will export the whole disk only?
unlikely - but: I can’t say

I have used other NAS devices. There where always options in the interface …

imarco · 14 December 2024 13:35

I’m on it

linux-aarhus · 14 December 2024 14:41

I am a littly rusty on NFS so I decided to check with my Synology NAS.

I have a shared folder named data and it is exported to NFS.

On my NFS permissions tab - info about the pount path is printed - you will likely have som similar information with a qnap system

imarco · 15 December 2024 07:18

2 things i forgot to tell:

i have a (old) synology and i will try to mount it with the same process
with another pc on windows (don’t bite!), it works with cifs (i just load a qnap tool and it works instantaneously)

With Syno, there is a problem too:

Most likely your IP address has changed since you setup your share.

That could be why you get the message

Another possibility is your mount point - as and old sysadmin - mounting a folder using root should never be in a user’s home folder.

When mount using .mount and fstab you are running the mount as root.

It is often better to create a single data structure originating from the root e.g.

/a/syno

Then assign permissions to the mountpoint either by setting the owner (single user system) or by adding the users to the users group and set permissions accordingly.
