If you’ve spent any time poking around the process tree on a modern Linux machine (especially RHEL/CentOS 7+ or Fedora), you’ve probably spotted a mysterious process called nfs-cfged .

It’s the configuration negotiation daemon for NFSv4.1 and later, specifically for pNFS (parallel NFS) and flex files . The Old Way vs. The New Way Traditionally, an NFS client learned everything about a mount from a single server. That server told the client: “Here are your files, here are your permissions.”

It sits there, using almost no CPU and very little memory. It’s easy to ignore—but when NFS mounts start acting up, knowing what this process does can save you hours of head-scratching.

sudo systemctl mask nfs-config.service sudo systemctl stop nfs-config On non-systemd distros, you may need to remove the init script or comment out relevant lines in /etc/default/nfs-common . Think of a traditional NFS server as a librarian who both helps you find a book and hands it to you.

nfsstat -m | grep -i "layout" If you see layout=flexfiles or layout=files , nfs-cfged is earning its keep.
