Pull from another nas with rsync

I’m on community GoldenEye and want to pull from another NAS to truenas. Therefor I followed the steps in Configuring Rsync Tasks | TrueNAS Documentation Hub and did this:

  1. created a rsync module on the second system
  2. under Data Protection I created a job using source a local share and remote server and the module name of step 1
  3. selected pull to make sure to pull from remote → source

Running the task says:

[EFAULT] rsync command returned 23 - PARTIAL. Check logs for further information.

EDIT: tried this with

rsync -av --progress scond-nas::module/folder /mnt/pool0/folder-mirror 

and it works fine
