Roon on Ubuntu server CIFs problem

I just converted a MacMini to Ubuntu server and installed Roon.
I’m getting a continuous stream of cifs errors even though Roon appears to function(at least for Qobuz)

“cifs: vfs: cifs_mount failed w/return code = -113“

No USB devices are plugged in. Any Linux folks have advice on how to resolve it?

Looking too closely at any OS logs during boot can cause many unnecessary headaches. I’m not saying nothing is wrong, but it is entirely possible that the OS is trying to create your network connections before the network stack has finished booting, in which case there is nothing to worry about. Again, I could be wrong, but I’ve learned these lessons the hard way, long ago. The most important thing is to test the functionality you need once the OS is fully booted.

Are you running a firewall on the server? Also, have you installed cif-utils?

The never ending stream of cifs errors occurs after boot up is complete. Cifs utils are loaded. So is firewall.
Any way to silence the errors so I can type commands without continual display interruption?

What happens with the messages if you turn off UFW?

sudo systemctl stop ufw 

No change, so I restarted ufw

Where is the local library stored? I’m guessing a NAS … if so, check there for errors as . That seems to use SMB 1.0, too.

What’s the output of … ?

smbclient //<server>/share --user <username>

Turns out I didn’t have smbclient installed. After installing smbclient am able to link the music server and use “ls” to list its contents.
The cifs messages still persist.
Do I need to delete the existing storage locations from the roon app and re-enter them the get roon to use smbclient instead of old cifs?

The error messages suggest that something is blocking access. This could be network or the Samba server. Therefore, check logs on that machine.

Since it appears to be working, even with errors, I’m thinking it could be related to IPV6, and this is closed (rejected) by the server. Do you have IPV6 enabled in the router?

You shouldn’t need to recreate the storage locations in Roon.

I don’t have ipv6 turned on.
The cifs errors ceased as soon as roon finished indexing the music library on my other Mac mini. When I did a roon backup the cif errors briefly returned. Other than the cifs errors roon on Linux is a big improvement over macOS.
The reason I changed to Linux was because Apple started randomly running high cpu mediaanalysisd causing roon to loose connections and HQPlayer NAA’s to disconnect.

That’s interesting. Since the errors only occur when indexing or during a backup, I think it could be that the NAS (?) is maxing out briefly, resulting in the connection errors. However, it would appear that retries are successful.

I reinstalled Roon and that eliminated the continuing stream of cif messages. Perhaps the order in which I added the dependencies was to blame. In any case thanks for your help - the issue appears to be resolved now.
