RoonServer on ubuntu with root music scan skipped almost 90% of my music

Roon Core Machine

I’m running roon 1.8.931 on ubuntu 20.04 server.

Number of Tracks in Library

17000 tracks in my library

Description of Issue

I’m running RoonServer on ubuntu 20.04 with samba shared, but I want the core running on ubuntu, So I can switch between Mac/Windows without losing my library.

But a very strange thing happened, My library are chowned to my own account, and the RoonServer is started with root. When I add storage to Roon, roon found I have about 17000 tracks, but after scan is done, only about 2000 tracks are scanned and showed in my albums.

I’ve tried mulitple times, but seems everytime I add music stroage always got same result, and this means about 90% of my tracks are skipped when scanning, and there is no error with roon, nor skipped tracks on roon’s window. Like roon found my library about 17000 tracks, but roon only think about 2000 files are actual music files. I tried with force scan, delete whole roon data folder. the resault always the same. Roon reported some tiff files error, then no error, 15000 other tracks are simply ignored.

as my music folder is also shared with smb, So I tried to scan my library on mac, mac as core, and this time every track are scaned without any problem, all my tracks are visible in roon ui.

No error, no skip log, Roon simply thinks that about 90% tracks are not music files when running on ubuntu 20.04 as core.

So how can I fix this problem?

I even tried to run roon server on same user with my music folder’s owner, seems the result are also same.

Martin_Webster · April 20, 2022, 7:40am

Core and Server are the same thing, so I’m a little confused by this. I assume you’re running Roon on Ubuntu, but where are the library files? And how are these presented to Roon, e.g., file path, share?

Steve_Yin · April 20, 2022, 7:54am

I’m running roon server on ubuntu, and my music files are stored on same server under /var/share/musics.

and this folder is also shared with samba.

when running server as core from ubuntu, roon ignored 90% of the music files without any error or ignore log. and of course, I run another roon on my mac connect to this core.

when running server on my own mac, all music files are recognized. roon access my music from samba share.

Steve_Yin · April 20, 2022, 7:58am

when running roon server on ubuntu, the roon server access my music from local file path /var/share/musics.

when running roon server on my own mac, my musics are accessed from samba share to /var/share/music on ubuntu server.

there are so many this kind of error when run roon server on ubuntu. maybe these errors are the actual reason of skipping my music files?

Steve_Yin · April 20, 2022, 9:06am

could this be btrfs problem? I mount my music disk as this:

/dev/sdc1 on /var/share2 type btrfs (rw,relatime,space_cache,subvolid=5,subvol=/)

Martin_Webster · April 20, 2022, 3:08pm

There’s no reason why btrfs shouldn’t work (I just tested this, and it is fine), albeit it’s unclear how and when you mount the drive. Personally, I would mount with fstab by disk-id at startup to a sub-volume, e.g., @music and mount this at /var/share/data (if that’s your preferred location.)

sudo mkfs.btrfs -L data /dev/sdc1
sudo mkdir /var/share/data
sudo mount -o subvolid=5 /dev/sdc1 /var/share/data
sudo btrfs subvolume create /var/share/data/@music

Your fstab entry would look something like this.

UUID=8844ca48-2157-4efe-8966-061e993a73f5 /var/share/data/music           btrfs   defaults,subvol=@music,noatime,space_cache,commit=120,compress=zstd 0       0

You have some discrepancies in your post, e.g., /var/share and /var/share2. Furthermore, why have you used subvol=/ when that would be where you mount the root filesystem or @?

Perhaps share the output from btrfs subvolume list /?

Steve_Yin · April 21, 2022, 1:52am

I have the whole sdc as one volume, and my fstab have this:

/dev/sdc1       /var/share2             btrfs   defaults        0 0

So, I don’t think there is something wrong with my btrfs problem. I created a 'Musicsfolder on/var/share2, then I set roon to use this /var/share2/Musics` as my library folder.

to my knowledge use Disk ID or dev path are both correct, the result are always same on any linux distro.

Steve_Yin · April 21, 2022, 6:51am

the problem here is, when run roon from ubuntu and add local path as music storage, roon simply ignore 90% of my files, and create a lot of errors above, I’ve checked the log, some album successfully recognized by roon don’t have those error log.

But if run roon on mac, and add smb share as music storage, everything works, no error, and no ignored music.

Martin_Webster · April 21, 2022, 8:10am

Please share the output from btrfs subvolume list /.

I doubt this is relevant to my problem

Martin_Webster · April 21, 2022, 3:41pm

Actually, it is. You failed to mention you’re running in Docker, and you have odd sub-volumes listed. Output from btrfs subvolume list / should look similar to this:

I’d probably disable btrfs support in Docker.

Steve_Yin · April 22, 2022, 2:00am

@Martin_Webster

No, Actually, it is not this problem, I’ve changed docker volume to ext4, then my btrfs subvolume list / show these

ID 3161 gen 972982 top level 5 path var/lib/portables
ID 3162 gen 972983 top level 5 path var/lib/machines

then I cleared /var/roon library, and add my music folder, there are still so many this kind of errors:

and the result are exact same like before, 90% of music files are simply ignored.

And I can’t believe this is btrfs or docker related, because I have a Synology NAS ds917+, which also have docker, all fs are btrfs, roonsever installed, and that don’t have this problem.

Fernando_Pereira · April 22, 2022, 2:41am

Peculiar. I’ve been running RoonServer on Ubuntu Server for 5 years, currently on 20.04.4 LTS. Music files used to be mounted via SMB from Synology, but for the last couple of years they have been in server-local ext4-formatted SSDs. I’ve never seen this problem.

Steve_Yin · April 22, 2022, 5:23am

@Martin_Webster

I have a 4T hard drive, device path is /dev/sdc, I created only one gpt partition on sdc as /dev/sdc1, then I created btrfs on /dev/sdc1 and mount it under /var/share2, then I created a folder Musics on /var/share2, I also have samba share on /var/share2. this server also run roonserver, If I use roon on this server and add music storage from /var/share2/Musics, then roon simply ignore my music files.

ever more strange things happened:
If i copy some folders to another disk which also is btrfs, then roon can see and recognize this. and these are files which roon ignored on /var/share2.

If I mount /dev/sdc1 to /mnt/test then add /mnt/test to roon then I have the same result: most of files are ignored.

If I run roon on my mac, and add those music from samba share, everything works.

Martin_Webster · April 22, 2022, 9:27am

I think your setup is atypical, and this is introducing a problem. And you do have an issue with Docker and BTRFS; that long list of subvolumes confirms this, e.g., undeleted BTRFS volumes.

Im still unclear whether you’re using EXT4 or BTRFS or both with Roon. If the media files are on the 4TB volume and that is BTRFS then you’re still likely having performance problems with Docker and BTRFS. Have you checked page caching and memory usage for that image?

As @Fernando_Pereira says, Roon Server runs well on Ubuntu. I’ve never experienced such issues, then again I don’t run Roon in Docker.

Steve_Yin · April 22, 2022, 9:49am

@Martin_Webster

I did not run roon in docker, docker are another service, roon are installed in ubuntu.

I’ve tried docker prune to remove all those unneeded volume, and the problem are still there.

I have a ds917+ which also have roon and music files are in local path, which runs perfectly. the fs setup is all btrfs, no ext3/4, my ubuntu server is same, only btrfs and no ext3/4.

Martin_Webster · April 22, 2022, 10:07am

It would be helpful if you explicitly state how things are set up when opening a thread.

Based on what you said earlier, this information is irrelevant.

If, as you say, you’re running Roon directly on Ubuntu with BTRFS, then it should work fine. However, your output from btrfs subvolume list / still looks wrong. Where is the / (root) filesystem and your home directory?

I’m using my mac and windows, both installed roon, and mac/windows roon connect to server’s roon and on this server, roon use local folder /var/share2/Musics as storage folder,

roon server running on ubuntu with local storage set to /var/share2/Musics => roon server ignore most of files
roon server running on ubuntu and on ubuntu, I use mount.cifs to mount samba share to /media/musics, then add /media/musics as storage, same result.
on mac/windows, if I choose not to use the roon server on ubuntu, and add music files by samba share, everything works.
