[CentOS] rpc.statd is not running but is required for remote locking.

Hello

I'm trying to mount a nfs system. But i receive this message:

mount  -t nfs  <IP>:/backup /backupnfs
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.
mount.nfs: an incorrect mount option was specified

After a fews searchs on google

i tried to execute the files:

sbin/rpc.statd
/usr/sbin/start-statd
