Hi, I am new to pydio. I just install pydio last week on my Debian 11 I want to use my FreeNAS as pydio datasource, the setting was complete, but when I tried to sync, it shows `Error: rename across devices not allowed please fix your backend configuration` followed by some token. Here is what I’ve done 1. Mount NAS pool to `/dataobs` in Debian (pydio user has rwx access) 2. create directory `/mnt/pydio/obs` (pydio user has rwx access to these dir) 3. create symlink `ln -s /dataobs /mnt/pydio/obs/data` 4. create new datasource by selecting Import Existing Data option then select `/mnt/pydio/obs` as data path Pydio user has read write execute access to these directories. I found .pydio file in /mnt/pydio. When I sync the datasource, it shows error log as I mention earlier. Can someone help me with this? ---

Similar problem: > [@Mount smb/cifs as datasource does not work in v4.2.2](https://forum.pydio.com/t/mount-smb-cifs-as-datasource-does-not-work-in-v4-2-2/5361): > > Installed pydio cells v4.2.2 on rocky linux 9, and wanted to use a smb/cifs share as datasource. This does not work and the datasource is shown as “Objects down”. Folder structure: /mnt/pydio/share /mnt/pydio can be read/write from cells, fstab mount entry is set to mount the share under the /share folder. Workaround/tricks with symlinks do not work either.

Thank you, it works. I read in that post, this cross-device is not supported for security reason. What could that be? And is it possible for developer to add some info about this when adding datasource? Something like “please note that cross-device won’t be supported” or something like that. ---
