NFSv4: Are portmap_enable, rpc_lockd_enable, rpc_statd_enable needed?

[littlesandra88]

According to the Red Hat Enterprise Linux docs

http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-nfs.html

then are portmap, rpc.lockd, and rpc.statd not needed on RHEL5 if NFSv4 is used, as their funtionality is in the protocol.

The FreeBSD Handbook doesn't mention this.

Question

Does that mean, that I can safely remove

portmap_enable="YES"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"

from /etc/rc.conf on my FreeBSD 9 server, when I only use NFSv4?

I believe that is correct.

@bbzz

Would you say I also could remove rpcbind_enable ?

Locking and 'stat' functionality is built into the NFSv4 protocol. If you don't need to fall back to NFSv3 then you don't need to start rpc_lockd and rpc_statd. As for the port mapper (rpcbind), RCng will auto-start it as a dependency for nfs_server.

That's right, I believe only nfsv4_server_enable="YES" is needed if you don't need NFSv3.
