Music library not reacheable because of SMB1

To use a NAS drive with Sonos, the NAS must support the SMB(v1)/CIFS file sharing protocol.

Or use a NAS to SMB v1 gateway for a more secure solution. See the thousands of other SMB v1 posts for more background on this issue.

NAS (any protocol) toSMB v1 gateway: https://stan-miller.livejournal.com/357.html

Hi thanks for your reply.

I used my NAS already for one year with the SONOS system to play the music library on the NAS DS 720+ without any problems.

After Synology release update to DSM 7.0 this service is not working anymore.

This however SMB1 is selected as minimum SMB protocol.

I tried to set back the SMB1 protocol, that Synology offers on his site. But the downloaded file cannot be set back to my NAS (SMBService-x86_64-4.10.18-0189.spk)  

and how can I find out if NAS supports SMB (v1) / CIFS file sharing? thank you

Hi @bentriviani 

This thread is somewhat out of date. Sonos S1 software still requires SMB1, but S2 software now supports SMB2/3, which all NAS servers support.

If you’re on S1, you’ll need to look up your NAS manual on how to make the changes to the settings.

I hope this helps.

@bentriviani You would need to check the manual for your particular NAS to see how to find/change that setting. 

Well, my library became unreachable exactly after I disabled SMB1 on my Windows machines (my library is on a Windows Server, NOT on a NAS device). So much for the thread being “somewhat out of date.”

But once I re-enabled SMB1, I still am not able to connect to my music library. This is a royal mess, folks. The music library set up starts, but after a few minutes I get the below:

Update: this is maybe NOT SMB1 after all. I still have no idea why I was suddenly unable to connect to my music library from any device (the day after I disabled SMB1). The standard suggestion is to remove your library and add it again.

However, my music library is around 100GB, and Sonos (S2) croaks a few minutes after trying to set up the library again. If I [re]build my library a little at a time, it works. But it has to be VERY little, and as you can see it takes time to do this for a library this large.

I see that this is a known issue - documented in other posts. One person even said that 1,100 is about the most that Sonos can bite off at a time.

Is there any intent to fix this? I can open a ticket if I don’t see a response - meanwhile I’ll rebuild my library a little at a time…

Just my 2 cents: my library contains abt. 64,900 items in 6,300 folders, 901 GB. Indexing takes between 5 and 10 minutes. You must have some other sort of problem, I'm sure.

I have/had the same problem. My music library is stored on a Synology DS920+ (SMB3). Using the S2 app I can connect no problem. Using the S1 app doesn't work.

However I can connect to my library with S1 app by using ‘Plex’.
