I was really struggling to get my NFSv4 server working properly - especially with configuring `idmapd` and making sure my exports were set up correctly. This guide broke it down so well, and I finally got everything running smoothly. The explanation of the `/etc/exports` options was super helpful, especially `root_squash` and `no_subtree_check` - I had no idea those settings could impact performance so much!

Can you please go to your server and do:

ls -ld /NFS-SHARE /NFS-SHARE/mydir

I need to see your permissions, the owner and the group of these folders, in order to troubleshoot some of my permission problems.

@JNat,
I am sorry it’s taken me so long to post a reply to your question. I used a Debian box as NFS server for this article, so it’s likely that some of the package name may differ a little. You may want to refer to this link for details on installing the server using a CentOS box: https://www.howtoforge.com/setting-up-an-nfs-server-and-client-on-centos-6.3. Hope it helps! Don’t hesitate to drop another comment if for some reason it doesn’t work for you – I promise to reply faster than this time.
On a side note, if you’re relatively new to Linux, I’d highly recommend you download The Linux Command Line from linuxcommand.org. It is by far the best introductory book to Linux.
Finally, thanks for your kind words about my work.

@Christopher,
The INVALIDARGUMENT message makes me think there must be a problem with your exports. Please refer to this link for the NFS server installation on CentOS 7, until I can revise this article and others in the LFCE/S series: http://www.server-world.info/en/note?os=CentOS_7&p=nfs

I have been trying to setup this up under Centos 7.1 but RPCBIND service is always giving an error when I check the status:

root@LFCE ~]# service rpcbind status

The LFCE exam is now using Centos 7! We need to fix this soon..
