How to Configure Immich to Use a Mounted or Remounted Storage Drive
Immich stores uploaded photos, videos, thumbnails, encoded video, and profile assets in its configured upload library. When a server gains a larger disk, a USB drive, a NAS mount, or a remounted storage path, the administrator can move Immich’s media storage there by changing the host path that Docker binds into the Immich container. The safest approach is to stop Immich, copy the existing library, mount the drive reliably, update the Immich environment file or Docker Compose volume mapping, then start the stack again and verify that the application can read and write normally.
