Roon didn't automatic add files anymore [Answered]

Hi @Da_Chen ----- Thank you for the continued feedback, and more importantly, thank you for your patience. My apologies for the slow response.

We’ve found that many NAS devices have issues properly communicating changes to OSX in particular. Roon leverages OSX’s network storage infrastructure for watching NAS drives, so if you’re migrating to this setup from local storage or a Windows Core, you’re probably feeling those performance distinctions. Basically, when OSX is aware of a change on the network drive, it lets us know and we update your library immediately, but we don’t always get that notification in as timely a manner as we would like.

However, in certain situations OSX can be unaware of changes, particularly if they are made directly to the network drive without Finder (on the Core machine) being involved. If OSX fails to notice the changes, Roon isn’t notified, and the changes don’t show up in your library until a rescan is triggered.

Unfortunately, we’ve found that most NAS’s just silently report a subset of events, or none at all. We did some research and found that just about every piece of software that attempts to do “real time watching” on NAS’s eventually runs into this limitation, and supplements it with a periodic scan of the storage folder. Plex does it, JRiver does it, so do others, and so does Roon.

Brian discussed some of that here, although I should mention that a few things have changed since then. We have some new plans for improving our real-time scanning, but I don’t have a time frame to report on when that work will happen. In the meantime, we’ve also made the rescan period configurable, so you can have Roon scan more or less often depending on your situation.

Moving forward, in the interest of having a better understanding what your experience has been like (based on the information cited above), can you verify the following for me:

  • In the Synology, can you confirm what your SMB settings are? If you’re not using SMB2 or SMB3, I would recommend trying that.

  • Having some more insight, procedurally speaking, in regard to this comment would be greatly appreciated:

“now i re-organize my files and list all of them with labels, the files are all into their labels folder, that’s the second class, so roon cannot found them instantly.”
