I’m trying to setup my first homeserver with pods alone but I can’t add my mounted /data (it’s an external HDD) folder to the root folder, but the /app and /config works. It’s a common issue but somehow I wasn’t able to solve it.

OS: Rocky Linux 9.3

External HDD (WD Elements)

external HDD in /etc/fstab:

# WD Elements drive
UUID=4655386a-5ccf-4c7b-ad6a-c0b90ccf8454 /home/privatenoob/media/storage1 xfs defaults 0 0

radarr.service:

[Unit]
Description=Radarr Movie Server
After=network.target

[Service]
ExecStart=podman run --name=radarr -e PUID=1000 -e PGID=1000 -e UMASK=002 -p 7878:7878 -v radarr-config:/config -v /home/privatenoob/media/storage1/Filmek:/data --restart unless-stopped lscr.io/linuxserver/radarr:latest
ExecStop=podman stop radarr
Restart=on-failure

[Install]
WantedBy=default.target

Permissions:

drwxr-xr-x. 2 privatenoob privatenoob 6 Jan 17 16:52 Filmek

drwxr-xr-x   4 abc    users    139 Jan 18 19:44 config
drwxr-xr-x   2 root   root       6 Jan 17 15:52 data

chown -R 1000:1000 /data didn’t work. It gave permission denied, even though I used root (probably this is because of -e PUID=1000?)

There are a few ways around it. The simplest is to add the –privileged option.

The more secure method with podman is by specifying a user (ex -u 10001:10001) from your extended subuid:subgid range after your full and proper setup of rootless podman :-)

Then instead of chown you’ll want to use the oddly named podman unshare tool to automatically set the permissions of the host directory. You would then want to start your service with systemctl --user instead of sudo systemctl

  Okay so I’ve done these steps (it seems rootless podman have been setup by Rocky automatically):
  
  Get subuid:subgid with /etc/subuid: privatenoob:100000:65536
  
  2.:Changed ExecStart to this: ExecStart=podman run --name=radarr -u 100000:65536 -p 7878:7878 -v radarr-config:/config -v /home/privatenoob/media/storage1/Filmek:/data --restart unless-stopped lscr.io/linuxserver/radarr:latest
  
  3.: podman unshare chown -R 100000:65536 /home/privatenoob/media/storage1/Filmek/
  
  Unfortunately unsharing gave me invalid arguments.
  
  chown: changing ownership of ‘/home/privatenoob/media/storage1/Filmek/’: Invalid argument
  
  I have tried by leaving the -e PUID=1000 parts on but those didn’t work either. Yeah and I’m using systemctl --user.

    Ah! I think I see the confusion.
    
    # /etc/subuid privatenoob:100000:65536
    
    This denotes the range of subuids that are available to your user.
    
    -u 100000:65536
    
    This part specifies two things ([UID]:[GID]) even though it’s the same syntax as the earlier part that specifies one range :)
    
    I suspect what you will want to do is use the following:
    
    # change ownership of the directory to the UID:GID that matches something in your subuid:subgid range, in this case 10000:10000 podman unshare chown -R 100000:10000 /home/privatenoob/media/storage1/Filmek/
    
    Then we can specify that the user in the container can match the user (UID) we specified above:
    
    ExecStart=podman run --name=radarr -u 10000:10000 -p 7878:7878 -v radarr-config:/config -v /home/privatenoob/media/storage1/Filmek:/data --restart unless-stopped lscr.io/linuxserver/radarr:latest
    
    As a note, if you copy/pasted that ExecStart line, you might have gotten the invalid argument error because you entered 100000 (outside of your subuid range, i.e. >65536) instead of 10000.
    
    There’s a nice guide that gives a great walkthrough. I’ll dig through my bookmarks and add it here when I get some time.
    
    Hope this helps!

On my OpenSuse server I had to add :Z after /data in the bind, dont know if it applies to your setup, but it is easy to test and see if it works

Are you doing rootless or rootfull podman? I am doing rootless and I have the following in my radarr container - PUID=0 PGID=0

source
- PrivateNoob@sopuli.xyz ⁨9⁩ ⁨months⁩ ago
  I’m doing rootless most likely, I just use the default Rocky Linux 9 setup with the Container Tools option turned on while the setup process. This didn’t work either for me. Did you start the service in sudo systemctl or in systemctl --user mode?

Try running the chown outside of the container: chown -R 1000:1000 /home/privatenoob/media/storage1/Filmek

source
- PrivateNoob@sopuli.xyz ⁨9⁩ ⁨months⁩ ago
  Doesn’t work either with both running this before starting/building the container and also while running it. Thanks for the help tho!

Drop the / in “/data” for the chown command. Now it is looking for a data folder in root, and not the one in “Filmek”. Don’t know if it will help with your issue thou
