Connecting a Synology network folder

[savas]

I'm using TrueNAS and I'm not quite sure how to do that or if I'm understanding you correctly. How do I go about doing that? Do you mean mount it via Additional Storage?

Mounting is adding it onto the OS in a way that makes it look like the shared network is directly attached to the system.
In windows, mounting would basically be adding it with a letter path so that programs could open it as if it was a drive attached to the system.

TrueNAS is built as a "locked-down" appliance. The developers behind it expect you to only use what is in the GUI they provide.
They give you the freedom to mess around with the system shell, but the developers don't support you there.

There's no way to mount network shares with the GUI. You'll have to use the system shell to do this, but this is unsupported.
What that means is that a future update may wipe out your mounted shares since they expect you to not install or change things outside of the GUI.

Thanks for the breakdown. It's only temporary so if it's something I can do just to get access to the media for the time being I can test out Jellyfin in more depth.

It would be easier for you to transfer over your data from the Synology NAS to your TrueNAS server.
Is there a particular reason you haven't done so yet? Does your TrueNAS server currently not have enough storage? Or is it because you can't afford the down time as you wait for the data transfer to complete?

A few reasons, yes. I'm using 3.5 drives on the Synology NAS, the goal was to move over to 2.5 ssd's, but haven't got the drives yet, in addition, if I am not mistaken when I move the drives over, they'll require a format, which requires empty drives.
