Hi! What’s not quite right with Roon?

Hi,

So I updated Roon this morning which has been running fine on my QNAP TVS-871 (i3 and 16GB ram) for years and now it won’t start with:

/share/CACHEDEV1_DATA/.qpkg/RoonServer/RoonServer/RoonDotnet/RoonServer: /lib/libstdc++.so.6: version `GLIBCXX_3.4.21’ not found (required by /share/CACHEDEV1_DATA/.qpkg/RoonServer/RoonServer/RoonDotnet/RoonServer)

I found the threads on here about setting up Roon as a Container, which I have successfully done. However, I’ve lost my DB and can’t seem to find a backup. How can I use the DB from my old install (QNAP Roon app) and import it into my Container roon?

Thanks

Dan

Hello @Dan_Mason ,

We have a new Docker QNAP install procedure for installing this, can you please confirm you followed it. Please use that guide for the updated setup on QNAP, you need to install RoonServer as an Application, not a container. Let us know if you need any help along the way.

I have the new RoonSErver applicatoin and using the yaml generator too, Roon is all working and streaming.

My question is, as my old install is still on the disk, how can I extract a copy of my old DB?

Thanks

the supported method is to restore it from a backup generated by RoonServer before the upgrade (remember the pre-upgrade recommendations that most of us ignored - disable storage locations & create a backup ?); if you don’t have a backup, short answer is you can’t & long answer is maybe (try instructions linked below , after you carefully identify the directory / share path to use; edit: if you need help with that, share screenshots of your docker-compose yaml & Roon relevant shares as seen in FileStation) ..

one of the steps listed below is a little more technical, and you will need to open a SSH connection to your QNAP NAS (How do I access my QNAP NAS using SSH?); also it assumes that you didn’t delete the RoonServer QNAP application yet (, but only stopped it from “App Center”); if you did remove RoonServer app, we can check if ROON_ID_DIR was removed too (from SSH connection, run command ls -l /share/CACHEDEV1_DATA/.qpkg/RoonServer/id ) and modify the cp command note: for the SSH connection, you…

Hey @Dan_Mason,

Glad to hear the new install is working and streaming properly. For moving the database, the best method is to restore from a backup, and if that backup was created before the upgrade, that is the supported path. There are other methods, like the one @yo3fxy shared, but those have not been tested or endorsed by us.
