[Bug]Seafile installation on NFS mounted drive("Invalid cross-device link")

[mjkent]

I am installing Seafile using the default docker compose.

I've mapped the MySQL container data to store on my host mounted NFS drive, as well as Seafile. MySQL starts up correctly(and all my other docker containers).

Here is the volume mapping:

  seafile:
    image: seafileltd/seafile-mc:latest
    container_name: seafile
    ports:
      - "8084:80"
#     - "443:443"  # If https is enabled, cancel the comment.
    volumes:
      - /mnt/media/seafile:/shared   # Requested, specifies the path to Seafile data persistent store.

SeaFile throws this error: https://github.com/haiwen/seafile-docker/blob/504639793b7b0626bc4ffbc8cf49537665cf038c/scripts/scripts_11.0/bootstrap.py#L222

Thanks for helping us resolve the issue. The reason is: os.rename only works if source and destination are on the same file system. So use mv instead of shutil.move (which contains os.rename).
