Scanning the media folder does not add new media

[dsides]

First of all, I'm a big fan of Subsonic, and I have even donated to the project. It works very well, and I rarely run into issues. Using dSub on my Nexus 4 is a treat, and I love how I can carry my entire music collection wherever I go. However, I've been having this issue below since I started using Subsonic back in November.

Problem Description: Whenever Subsonic scans for newly added files in the "Enabled folder", it doesn't discover them. The only way I can get Subsonic to see my new files, and folders (if there is a new artist) is by first clicking "Clean up database" and then deleting the media folder, and re-enabling it. Simply forcing Subsonic to scan the media folder does nothing. I have tried clicking "refresh" but that does nothing.

Any help would be great.

Troubleshooting Steps: None. Other than what's stated above.

Playback Application and version: Remote web interface via (Firefox or Chrome) and dSub on various Android devices.

Having the same issue.

Subsonic is working great so far but recently I added new files and Subsonic only registered the folders but not the content of these folders as if they were empty.
I refreshed many times, updated the database, cleaned the database, nothing can seems to work and the log doesn't state for any error.

Is there a way to activate a debug log ?

I checked the rights and they are all the same than the other files that have succesfully been registered before.

This happened without having updated anything neither on the server nor on Subsonic so I really don't understand what is happening here.

Regards.

I guess I'm on something ...

After many refresh/database cleanup/folders scan, nothing changed, I can see the folders in Subsonic but they are empty.

I moved my empty folders to the "Incoming" folder and then, everything is fine in "Incoming".
I then move them from "Incoming" to my root folder (where they were before) and now, everything is fine.

Maybe an option to force rebuild of the folder structure/database would be nice since it seems clean databse/scan folders doesn't work well.

[ksn]

I am having the same problem as the original post. My library is currently linked to a network drive \\ipaddress\music.

Scanning does not update new songs. I have to delete the folder, clean up the database, then rescan the folder, which takes a considerably long time.

I have 13 days left on my trial and would really like to upgrade to pro, but not if I can't figure out why I can't easily update the library.

Any help is appreciated,
Thanks!

How do you have your drives mapped?

I had mine mapped from my server (running Linux) to a Windows PC (where my media is stored) as follows: (each line was a separate mapping, and a separate Windows Share)

\\server\media\music\
\\server\media\videos\
\\server\media\audiobooks\

And then in Subsonic, had each of these as a separate media folder.

When I figured out the problem as being a WINDOWS issue, I made changes to the IRPStackSize, but this would work for a while and then crap out again until I increased the IRP again, rebooted, synced, and waited for it to crap out yet again.

So, I made the following changes: On my Windows machine, I moved all of my media into a single folder/share called "Media", and mounted this single share in Linux as \\server\media\media\.

And then from Subsonic, I used the following as media folders:

\\server\media\media\music
\\server\media\media\videos
\\server\media\media\audiobooks

And I haven't run into the missing folders issue since.

Thanks, I'm not sure what an IRP Stack is. My Subsonic is installed on a Windows 7 machine.

I have an external drive connected to my router (airport extreme). Currently, I'm accessing it through \\ksn\music\ and in Subsonic I have it set up as \\ksn\music\ as well.

Do you mean, I should set up the subdirectories in Subsonic? So like:
\\ksn\music\rock
\\ksn\music\instrumentals

If your Subsonic is installed on the same PC as the one where you store your media, then you probably won't need to edit the IRP - that's mainly for accessing files from another computer.

Here's how I have mine configured in Subsonic:

And how it's set up on my Windows machine:

I have the "Media" folder shared on Windows, and mapped to my Linux server. Previously, I had each of the subfolders as a separate share (ie. "Music", "Movies", and "Audiobooks", and each of these mapped to Linux separately.) This is where the IRP thing came into play - too many network connections to the same computer.

If your media is on the same computer as Subsonic, then in the media folders section, you should be able to just enter C:\Music or D:\Music to the paths - you don't need to enter the full "UNC" path.

Settings/Media folders - uncheck all folders.

Scan with all folders unchecked.

Clean db

Recheck all media folders.

Scan library

Enjoy

This works for me almost every time but I feel like this needs to happen to frequently when using it with network shares.

I'm certainly not suggesting that this is the way it should work - just merely sharing what I've found to be helpful.

I've moved all my sites to the Madsonic fork and find it to be very stable and not as prone to this issue.

There have been many nagging issues that never seem to get fixed with Subsonic, but I'm not the developer and can't explain why some of the persistent problems never get addressed. The underlying db crashes and failures are repeatedly referenced in posts, but never seem to get fixed. Hakko frequently posts about the shortcomings of the db Subsonic uses and has moves to Postgres in his Music Cabinet fork. MadEvil, Hakko, and Bushman4 have far more expertise in this area than I and many of their posts contain additional information on this topic.

I've moved to the Madsonic fork on a Windows Server platform using the latest Java version and 64 bit Tomcat 7 to run the war version. I am very happy with the features, stability, and integration with the Madsonic Android app.

YMMV

HTH

Additionally, MadEvil is very active on his forum site and addresses users questions and issues very quickly.

I tried installing Madsonic, it's pretty cool, but same issue with scanning new media. Have to clear DB and rescan in order to add new files.

[GJ51]

Did you do a "Clean" install - removing all traces of any previous installation first?

I have two instances of Madsonic running and neither has any of the problems you're having. We add music almost daily without any problems. If you're installing over the old db you're most likely retaining the original defect that is causing the issue.

Save the data directory in a backup area. Uninstall Subsonic/Madsonic, delete the data directory, uninstall java.

Reboot the host machine, do a clean install of Java to the latest version, then install the latest version of Madsonic. This will generate a new clean db to start out with. Then start adding your music media folders.

[ksn]

Hmm, I uninstalled Madsonic, deleted the folder in Program Files, reinstalled and after changing a couple settings, all the music was back without having to do any scanning. What am I missing in the uninstall?

[GJ51]

The data directory with the database - in Windows it's stored at C:\Subsonic.

The error is most likely in the database. When you reinstall any Subsonic version it will look to see if the data directory is still there and then use it. To generate a clean db you need to delete the original data directory first if you want a new clean db.

I'm not that familiar with Linux, but I think it's in something like var\Subsonic.
