[ovirt-users] Using a synology as an nfs storage

Hello, I'm setting up a 3 node cluster with the ovirtnode iso and a seperate server with the engine on and a synology for nfs storage. I have done my configuration and I'm able to mount the share manually on the node with a command. Also on the server with the engine on I can mount it manually. But when I want to do it through the webinterface to add a data domain it say the permissions are wrong. Any idea's on how to figure this out ? Kind regards.
