Dietpi: Move radarr database folder to ssd.

[Dr0bac]

I tried to move database folder to the new drive without success.
First i stoped radarr service service radarr stop
then i plugged ssd to raspberry pi, pount point is /mnt/database
then i edited /etc/systemd/system/radarr.service to change -data flag

and finally i moved database folder from /mnt/dietpi_userdata to /mnt/database
and when i started radarr with service radarr start i got warning:

Warning: The unit file, source configuration file or drop-ins of radarr.service changed on disk. Run 'systemctl daemon-reload' to reload units.

And radarr created new database folder on /mnt/dietpi_userdata and it using this folder, and not the one i moved to /mnt/database

when i entered systemctl daemon-reload i got this error:

What should i do?

Hi,

Did you check for correct permission? Looks like Radarr is not allowed to write to the new location. What file system format you are using on the SSD?

Cannot create AppFolder, Access to the path /mnt/database/radarr is denied

[Dr0bac]

I know that @MichaIng hardened permissions of radarr/sonarr programs..
I see in .service file ReadWritePaths=/opt/radarr /mnt

So /mnt us included then?

[Joulinar]

I guess that's the path for storing download

[Dr0bac]

What should i do? What permissions to set to this ssd?
I want to move database folders of radarr, sonarr, bazarr to this ssd.

[Joulinar]

best is to copy files with current permission cp -p. Still the question. What file system format you are using on the SSD. Another option is to move whole /mnt/dietpi_userdata to your SSD, or you move whole RootFS, or (if supported) the entire system

[Dr0bac]

Last time i tried to start radarr i didn't move database folder, and radarr tried to make new radarr database on /mnt/database and it failed, and i guess radarr make database folder with correct permissions. So if i move radarr folder with -p sign i guess it will be the same.. ssd is formated with ext4. I can't move whole mnt/dietpi_userdata, i have 300 gb of movies there..

[Joulinar]

I guess you need to give r/w access for radarr user to /mnt/database all related files. If you copy all files with cp -p, permission will be keeped. That's what -p does. Worst case scenario is to use 777 permission.

Please try:

chown -R radarr:dietpi /mnt/database

General hint: Do not edit /etc/systemd/system/radarr.service directly, as this gets overwritten on reinstall. Instead create an override config in e.g. /etc/systemd/system/radarr.service.d/custom_database.conf with only content:

[Service]
ExecStart=/opt/radarr/Radarr -nobrowser -data=/mnt/database/radarr

to override the start command. This can be done as well via dietpi-services > radarr > Edit.

Thank you!
