My error is:
mount.nfs4: access denied by server while mounting fileserver:/export/path/one
My question is:
where would the detailed log information be on the server (under systemd)?
I asked a similar question from the Ubuntu client perspective on AskUbuntu. My focus in this question is on the Arch Linux server. In particular, I am looking for logs on the server that will help me understand the problem.
Here's the background:
Our small LAN is running an Arch Linux NFS v4 file server. We have several clients running Ubuntu 15.10 and 16.04. We have one client running Ubuntu 14.04. The 14.04 client will not connect to the file server. The others all connect fine. The settings are the same on all clients. And all clients are listed in /etc/exports on the server.
I need to find more detailed error information on the Arch linux server. However, journalctl does not show anything related to nfs and it does not contain any entries that are related to the nfs access denied errors.
The 14.04 client can ping the fileserver as well as log in via SSH. The user name / ID as well as group match. (I'm using the same user account / uid on both client and server. It is uid 1000.)
Even more info:
$ sudo mount -a (on client)

The fileserver can ping the client.
