Hej, Would you mind giving a short guide how to correctly setup Home File-System on NFS? Documentation just informs that: "If you choose Other, then no configuration for a home file-system will be done. In this case, you won’t be able to add any cluster users without further manual steps to setup a home file-system." Cheers, Iggy
