I have a TrueNas Scale NAS as my primary server and I want it to back up to an old Drobo 5N2.I installed SyncThing on both devices and created shared folders via the Drobo. Syncthing seems to see both devices. The folders all show as “Up to Date”. The problem I’m having is that neither device shows the other as ”Connected”. The TrueNAS device shows the Drobo as “Disconnected (Unused)” and the Drobo simply says “Disconnected”. I have tried adding a file to one of the shared folders and it never appears on the other side. The versions differ between the tow instances of Syncthing. The TrueNAS version is 2.5.10.3 and the Drobo version is 1.2.1. I would install a newer version on the Drobo, but no binary exists currently. Is it possible the version mismatch is causing this problem? I’m open to any suggestions. My goal is for the Drobo to serve as a backup for the TrueNAS system. Thanks in advance for any help or suggestions.
“Disconnected (Unused)” means that there are no Folders being shared. Share a Folder from one side, and accept it on the other. Syncthing 2.x and 1.x should be cross compatible.
Thanks so much for the reply. It looks like my knowledge of syncthing is lacking (no surprise there!). I didn’t know I had to accept a share. How is this done? Can it be done from the GUI?
That’s usually the easiest way. If you have a Folder you want to share ready to go, click Edit, go to the Sharing tab, and check the box for the Remote Device you want to share the Folder with. On the other Device, open the GUI and there should be a dialog box asking if you want to accept the shared Folder. Once it’s accepted you’ll configure the local directory for the Folder to use, among other options.
“Unused” means that there are no Folders being shared, no matter if it’s connected or disconnected.
This would only work if the TrueNAS was connected to the Drobo i.e. it was “Connected (Unused)”. If it’s disconnected, there’s no connection to advertise the share over.
I doubt this is sharing related, it seems like a connection issue, especially since the TrueNAS doesn’t show as “Unused” on the Drobo, which implies the Drobo shared a folder with the TrueNAS.
Versions 1.29.6 and newer are not compatible with versions 1.2.2 and older. OP is running version 1.2.1.
Thanks for the corrections sir!
Rats! Thanks for the information. I kind of guessed the versions had something to do with it. I guess if I want to continue, I’ll have to try and rebuild syncthing for the drobo with current sources. I’ve never compiled an app for a drobo before, so this should be interesting. I’ll need to find a cross compiler for ARM processors, though
I briefly looked into this and from what I’ve seen, the drobo distribution for syncthing just downloads the official (precompiled) releases: droboapp-syncthing/app.sh at master · vrillusions/droboapp-syncthing · GitHub
(However, the script will need to be adjusted for syncthing v2, as it uses old-style command flags which are no longer supported by any recent version)
