Old thread I know, but thought I would respond that what the OP is trying to do is technically possible. I'm looking to do something similar and found a way, but still testing to see if there are any downsides. I have reasons that I need to keep my mp3 and flac files separate, but I don't want users have to navigate down separate trees to see albums by the same artist. Following Spaceinvader One's video How to setup a root share in unRAID, 1 share to rule them all! 2 Minute Tips Ep 02, I was able to use that infomation to solve this problem. Here is what I did:
1. Create a share called "Music" and set to one drive (disk1)
2. In that share, create at least one folder. I use folders with single letters and then put artists under those, e.g. "A\ABBA", or "B\Brahms". So, I just created the folder "A"
3. Edit the share and set it to a different drive (disk2)
4. Open the share and create a different folder, e.g. "B"
5. Edit the share and set it to both drives and make it read only.
6. Under Settings\SMB I added the following under "Samba extra configuration"
[MP3]
path = /mnt/disk1/Music
comment =
browseable = no
# Public
public = yes
writeable = yes
vfs objects =
[Flac]
path = /mnt/disk2/Music
comment =
browseable = no
# Public
public = yes
writeable = yes
vfs objects =
This creates two new shares that are hidden, but writable. User can go to the "Music" share to brows and play any music (MP3 or Flac). But, to write new files I would have to go to the MP3 or Flac shares created through the SMB settings.
