Environment:
a PC with samba server enabled as a storage connected with GbE to the Roon Server machine. The player a COS H1 DAC connected to the USB port on the Roon Server machine.
Thanks for providing that information and for attaching those logs. The Core machine does appear to be quite a bit under spec’d, our recommended guidelines can be found here.
As for the main issue at hand, there are two things:
The logs are saying that you appear to be out of space on that ROCK device’s database directory.
You are not using the newest Roon OS version, the current one is build 174. You can click on the “Reinstall” button in the ROCK WebUI to upgrade it and I would make a backup of your current db first.
I would first try to make a backup of your current database, save it somewhere safe, perform the update to build 174, then possibly look for a bigger hard drive and better CPU for your ROCK. Our suggested ROCK hardware can be found here.
I click on the “Reinstall” button in the ROCK WebUI.
After it have done the reinstall (it shown update successfully), I found the Roon OS version is still 1.0 (build 159) stable.
Is there anything I need to take care?
I was afraid that might happen. It looks like your ROCK is out of space and it can’t perform the upgrade to the newest OS. I would go ahead with making the database backup and upgrade the hard drive/CPU first. After the new drive is in place you can restore and upgrade the ROCK firmware as it will have more free space available.
