the diskspace on the server I’m using for lemmyfly.org is getting full (it was 40GB local volume, and it’s at 80% now) I can get extra volumes at my hosting (Hetzner) but is it possible lemmy looks at different volumes for the volumes folder that contains pictrs, postgres and lemmy-ui ?

Or do I need to move the complete main lemmy folder to this other volume and run lemmy from there, leaving my system-volume unused for lemmy ?

    Server admin here, you can do this in a way that avoids lemmy even knowing anything has changed. Read through all of this and do some googling first if you don’t know the specific commands to use!

    First, you need to set the remote volume to automatically mount correctly on system restarts. On Linux, this is done by adding an entry for it to /etc/fstab if one does not exist already. Once done, ‘mount -a’ will mount the volume.

    Mount your remote volume to the filesystem and rsync the folder you want to migrate off-server to it. Take the lemmy service offline, rsync again to catch any changes from when you started.

    Now, you can move the old folder that lemmy has been using elsewhere - I recommend renaming it by appending “.old” or something.

    Next, you need to make a symbolic link. This link should point from the old folder’s original path and point to your remote volume. Once done, make sure everything is there and that file permissions match the ones in your .old folder - file permissions are important and you may need to recursively set them if your lemmy service runs on a different user than you were making these changes with.

    Finally, say a prayer to the machine spirit, waft the holy incense, perform the ritual whack with a wrench, and start the lemmy service. Make sure everything is running properly before you walk away!

    The only issue you’re likely to run into is that remote volumes are constrained by network bandwidth. This may slow down load speeds, so some kind of CDN caching solution is recommended.
