Move Seafile data to mounted samba dir

Hello. I mount samba dir to /storage, next I copy all files from /var/seafile/shared/seafile/seafile-data to /storage, delete seafile-data dir and create link ln -s /storage seafile-data. But Seafile doesn’t start. Error from log:
*** Running /scripts/…
Traceback (most recent call last):
File “/scripts/”, line 63, in

call(’{} start’.format(get_script(‘’)))

Seafile installed using docker. What is wrong?

Has the seafile user permissions to read/write/exec the mounted folder? Or use symlink?
