Description of the bug

At startup, Jellyfin scans media mounts for drive space, which leads to large delays. The delay varies between 6 to 12 minutes. During this time, I can hear the drives actively working.

Reproduction steps

  1. Have multiple large media mounts
  2. Startup Jellyfin 10.11

What is the current bug behavior?

Delay in startup.

What is the expected correct behavior?

Option to disable scanning media mounts or some improvement in speed.

@enter-a-random-username commented on GitHub (Jun 10, 2025):

I had that in the beginning, but at the moment it takes a few seconds. Did a lot of cleanup and queries got a lot of optimizations,
Maybe i misunderstand the definition of large.

I run on optimistic and Jellyfin DB runs on NVMe and cache for DB on /tmp that is mounted to tmpfs.

Do you use a trigger on application start for scheduler tasks?
