I travel quite a lot and I’ve recently been adding more CDs to my library only to realise I didn’t force a rescan of the storage on the server.
My Server is a Headless Mac Mini M4, with my music stored on a Synology NAS. The music is accessed from the NAS by the Mac using NFS mounts. As the music isn’t held on the Mac the auto recognising of new tracks doesn’t work so I have to manually force a rescan.
Anyway, it would be great if I could also force a rescan from the Arc App.
There is an auto-rescan interval - this should work.
Maybe I missed it, where is that located ?
In the settings of the watched network share in Roon, I think
It’s somewhere - many NAS devices don’t properly announce new files over the network, and a regular auto-scan is the normal solution. @DDPS can you tell us where the NAS sync interval setting is?
Well the inotify based file “announcement” is more relevant when using local (non-network) drives (i.e., RoonOnNAS with local NAS storage).
The Automatic Rescan Interval is only available when using networked storage volumes. And while @James_H is indeed using networked storage, Roon doesn’t know that right now because his configuration is pointing to the local mounted volume rather than the “raw” SMB mount.
If @James_H reconfigures his storage location to point to smb://{NAS address}/music instead, then he should see the Automatic Rescan Interval setting, I believe…
That said, he might not even need the Automatic Rescan Interval if he wishes to use the tips at A Roon on (Synology) NAS Primer to increase the inotify limits on the NAS.
Thanks for the replies. I moved away from SMB as I had previously used it for Plex and Synology and it was ok for a while until Apple changed something in Sequoia. NFS works well for me with the Mac running Sequoia 15.5 and I use it for more than Roon. (I was going to use wireshark or something similar to see what network calls were being made from my desktop to the Mac Mini then see if I could set my own task up)
@DDPS thanks for the link to your post of runing Roon on your NAS, we have a smilar setup, I run pfsense and have a 1621+ with a 5 bay expansion. I work with docker daily but don’t run much on Docker on DSM at home, I prefer to run Roon natively on the Mac Mini.
On a side note with the recent changes to Synology and their own hard drive lock-in I’ll probably be moving over to something else and end up with TruNas, but that is a different story.
So back to my current issue with NFS and not automated way of rescanning my storage I will wait to see if Roon adds this. Even if interval scanning was available it would be good to be able to force scan from the Arc app.
As a longtime Synology fan, I am not taking this as a doom-and-gloom scenario.
First off, Synology always had a list of certified drives they would support; that’s not new at all. But while they came out of the 2025 starting gate stating that their new models would only support their own, they also noted that their process would extend to third party drives, just with a more rigorous process, and just a few days ago, they became more transparent:
Important part quoted here:
Chang added that Synology will soon make third-party hard drives compatible with its new NAS drives.
However, they must comply with Synology’s compatibility policy and undergo the same rigorous testing.
“We still welcome third parties to join Synology’s ecosystem and have invited vendors to join our validation program,” he said.
“We have a standard that requires more than 7,000 hours of testing and meeting a strict benchmark.”
And then there is this:
Interestingly, the compatibility page no longer allows you to look up any xx25 products at all right now, e.g.:
Whereas a couple weeks ago, they did indeed list only their drives.
I think this is moving a bit, and expect some openings moving forward. For me, so long as WD decides to go for the new certification process, I will be happy.
