for those struggling with permissions with dev folder.
nfs creates a root:root with 775 permissions and fog ftpuser isn’t part of that group
Just use setgid feature on filesystem . it will enable inheritance
first change the owner of the folders and make “users” the group , lets say fog is your ftp user
chown -R fog:users /volume1/images/
#set inheritance to the dev folder
chmod g+s /volume1/images/dev/
now every new file under dev will have the directory group owner
