NextCloud Verzeichnis auf OMV Folder legen

Hey, i setup my NextCloud and want to set my Data Directory to a Shared Folder in my Open Media Vault Raid. But Nextcloud doesn’t have any Permissions to this Folder. Does anyone know how to add permissions without taking all permissions from OMV.

Links to my shared Folder Raid: /srv/dev-disk-by-uuid-003db74c-0da1-4372-90e1-30dc19c9f61c/nextcloud

Looking forward to fix the problem.
