statd records information about each monitored NFS peer on persistent storage. An NFS server can use this hostname to send asynchronous GRANT calls to a client, or to notify the client it has rebooted. The Linux NFS server can provide the client’s caller_name or the client’s network address to rpc. statd.

Why is RPC-statd and nfslock not enabled?
So at the time of system restart as rpc-statd and nfslock service are static and not enabled, there is an alert in monitoring system that statd is not working. Now we want to start only rpc-statd and nfslock service and do not want to start nfs service at the time of server restart.
What to do if rpc.statd is not running?
After making changes to /etc/services, restart rpcbind in client with command “rcrpcbind restart” and test your mount again. The file /etc/services had been incorrectly modified and the word “rpcbind” was missing from “sunrpc” lines.
Why is my NFSD and statd not working?
The strange thing is that nfsd was still running, but statd wasn’t. After a reboot, nfsd also didn’t work (because it needs rpcbind ). It’s almost like these files disappeared while the system was running.
