SOLVED: Sync Progress Stuck at 0%

[Maoam]

System Information:
Operating System: Ubuntu
Installation Type: Baremetal

Problem Description:
Two days ago, I attempted to directly connect my NFS-linked local folders in Jellyfin by adding the path
nfs/{IP}.
When I tried to save this, the interface prompted me to enter a valid path. Thinking that it was looking for the NFS folder path, I appended a
'/' to the end and saved the changes.
However, when I initiated a library sync, the progress remained stuck at 0%. This issue persists across all scanning attempts, even after deleting every library entry. Currently, with no libraries configured, the sync still halts at 0%, prompting me to stop the Jellyfin server temporarily.

Steps Taken:

• Attempted to add NFS path in Jellyfin.
  
• Modified path by adding '/' at the end.
  
• Deleted all library entries in an attempt to resolve the issue.
  

Current Status:

• No libraries are configured, yet sync progress is consistently stuck at 0%.
  
• Jellyfin server has been stopped temporarily due to this issue.
  

Any assistance would be greatly appreciated. Thank you!

It says, UnauthorizedAccessException "permission denied." Do you have the correct user permissions set for Jellyfin to access the folder? It also looks like the directory watcher is /. That don't seem right. Open your nfs folder in in your file browser, and if you have access, try to use that path.

Thank you very much for your reply.
The correct nfs path ist actually /mnt/nfs/... while in the logs it say's /home/myuser so. I guess your right and jellyfin doesn't have the permission for the user home directory. My thought is that when I saved the '/' path it saved the user homedirectory to the Library and since the first scan kicked in it keeps looping every time when a scan starts, which fails every time duo to the directory permission issue. The question is why does it still want to access over and over again, even tough I did remove every single library.

Open your nfs folder in in your file browser, and if you have access, try to use that path.

Accessing the actual nfs directory mnt/nfs/ and it's files works without any issue via ssh.


I guess one thing I could try is granting jellyfin the homedir permission and see if the issue resolves it self, which I will try as soon as I am at home again.

In the meantime, I welcome any other potential solutions.

"/" is stuck somewhere in jellyfin's database and all the config files that define your libraries probably no longer have it. Another user had this issue. I recall they opted to just start from scratch.

Never do this.  If you have files that a service user frequently needs access to you should relocate the files.  Your home is YOUR home and has sensitive files in it that NO ONE should have access to.

Thanks for your advice!
I’ve decided to reset my Jellyfin setup based on your suggestions, rather than tampering with dangerous permissions.

I really appreciate your help!
