Describe your issue
Hello everyone, thanks in advance for your support. 
My setup currently consists of yunohost (vm), Qnap NAS and the Nextcloud App.
I want to use a nfs share as /home/yunohost.multimedia/ folder. My Yunohost VM only has 56GB HDD and my NAS has 3TB.
I have successfully moved the yunohost.multimedia folder, mounted my nfs share to /home/yunohost.multimedia and copied the files back.
After the I checked the permissions and did chown and chmod to match the old folder.
I can now upload new files and folders.
BUT I cant delete anything in the /home/yunohost.multimedia/share folder or the share folder itself.
As far as I checked the ACL is different and I tried to set it back.
But I get “setfacl: /home/yunohost.multimedia/: Operation not supported”
Thanks again for your help.
Kind regards Hans
