Rpc.statd

Overview

A daemon that listens for reboot notifications from other hosts, and manages the list of hosts to be notified when the local system reboots. Used by NFS locking mechanism.

Prevent to Boot

chkconfig --level 2345 nfslock off

Handling NFS Locking in Absence of rpc.statd

If we attempt to mount a NFS file on a host that does not run rpc.statd, we get this:

[root@shrike rackstation]# mount -t nfs 192.168.1.4:/volume3/nopartnerwiki /rackstation/nopartnerwiki/
mount.nfs: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd.

For front-end machines that are designed to exclusively access the remote storage, maintaining local locks might be acceptable. TODO: do more research on that, this is just intuition by now. What exactly does a NFS lock do?

In order to maintain local locks, mount like this:

mount -t nfs -o nolock 192.168.1.4:/volume3/nopartnerwiki /rackstation/nopartnerwiki/
