Best Way To Mount A Directory on Boot (lemmy.tf)

Basically I have a Navidrome container and it's pointing at my music in a network mounted folder, what's the best way to ensure that it's always there, even after a reboot of my Pi?

Add it to your fstab

Assuming systemd, create a file like

/etc/systemd/system/dir-to-mount.mount

And then configure it per the systemd docs:

https://www.freedesktop.org/software/systemd/man/latest/systemd.mount.html

Then modify the docker unit file to have a dependency on the mount unit so it's guaranteed to be up before docker starts.

Is this method superior to fstab?

[–] [email protected] 3 points 10 months ago* (last edited 10 months ago)

It has the benefit that the container can't start before the mount point is up without any additional scripts or kludges, so no race conditions or surprise behaviour. Using fstab alone can't provide that guarantee. The other option is Autofs but it's messier to configure and may not ship out of the box on modern distros.

[–] [email protected] 2 points 10 months ago

I'll let you in on a little secret: Fstab gets converted to mount units anyways.

[–] [email protected] 4 points 10 months ago (1 children)

Everyone's saying fstab but if Navidrome is in a docker container, just mount it as a volume on your container. I found this guide that seems to document it fairly well.

https://phoenixnap.com/kb/nfs-docker-volumes

This is how I'm handling NFS mounts in my docker stacks.

So this is my preferred method, but I found the blog post really confusing. Subsequently, it failed.

  navidrome:
    container_name: navidrome
    image: deluan/navidrome:latest
    ports:
      - "4533:4533"
    environment:
      ND_SCANSCHEDULE: 1h
      ND_LOGLEVEL: info
    volumes:
      - "/opt/navidrome/data:/data"
      - "/nfs/Shared Music:/music:ro"
      - type: volume
      - source: nfs
      - target: /nfs
      - volume:
        nocopy: true
  volumes:
    nfs:
      driver: local
      driver_opts:
        type: nfs
        o: "addr=XXX.XXX.XXX.XXX,nolock,soft,rw"
        device: ":/mnt/HD/Public"

What am I doing wrong?

[–] [email protected] 2 points 10 months ago (1 children)

I'm rather confused by the config you posted. The NFS config should all be down in the volumes: section the only thing you reference in the service section is the name of the volume you define and the path to mount in the container. Something like this (tho I'm guessing as to what should be what with your setup).

services:
  navidrome:
    container_name: navidrome
    image: deluan/navidrome:latest
    ports:
      - "4533:4533"
    environment:
      ND_SCANSCHEDULE: 1h
      ND_LOGLEVEL: info
    volumes:
      - /opt/navidrome/data:/data
      - music:/music
volumes:
  music:
    driver_opts:
      type: nfs
      o: "addr=XXX.XXX.XXX.XXX,nolock,soft,ro"
      device: ":/nfs/Shared Music"

Thank you so much.

One more question, do I have to point it directly at the directory I want or can I point it at one above? Reason being, I have a film directory which I will point Jellyfin to too.

[–] [email protected] 2 points 9 months ago (1 children)

You can point it to any nfs file system you have exported on the file server. That's entirely up to you.

[–] [email protected] 2 points 9 months ago

Thank you

[–] [email protected] 4 points 10 months ago (1 children)

fstab will do it, but the more important question is, what do you want to happen when it doesn't mount properly? Do you want the system to fail to boot? Do you want navidrome to not run?

[–] [email protected] 1 points 10 months ago (1 children)

Navidrome to not run would be optimal

[–] [email protected] 3 points 10 months ago (1 children)

It's probably best to wrap navidrome in a script that checks for the mount then.

[–] [email protected] 1 points 10 months ago

Thanks for the advice, I'll look into it.

[–] [email protected] 2 points 10 months ago

It sounds like you’ve got your solution already, but just in case someone stumbles on this later, I thought I’d mention autofs.

I’m coming to prefer it over fstab entries because it handles disconnections nicely and attempts to reconnect. Worth checking out for those who haven’t played with it.

[–] [email protected] 2 points 10 months ago

Call me old fashioned, but fstab...
