Linux – How to NFSv4 share a ZFS file system on FreeBSD

freebsdlinuxnfszfs

Using FreeBSD 9, and created a ZFS file system like so

zfs create tank/project1
zfs set sharenfs=on tank/project1

There are many howto's on setting up NFSv3 on FreeBSD on the net, but I can't find any one NFSv4 and when the NFS share is done with ZFS.

E.g. this howto say I have to restart the (NFSv3) by nfsd -u -t -n 4, but I don't even have nfsd.

When I do

# echo /usr/ports/*/*nfs*
/usr/ports/net-mgmt/nfsen /usr/ports/net/nfsshell /usr/ports/net/pcnfsd /usr/ports/net/unfs3 /usr/ports/sysutils/fusefs-chironfs /usr/ports/sysutils/fusefs-funionfs /usr/ports/sysutils/fusefs-unionfs
#

I don't see any NFSv4 servers, which I could install with pkg_add.

Question

How do I install and setup NFSv4, so I can mount the share from e.g. a Linux host?

NFSv4 is built in on FreeBSD (Experimental support in 8.x, production quality in 9.x and lter).
The nfsd should be located in /etc/rc.d/nfsd

You should first enable it within rc.conf file or running /etc/rc.d/nfsd onestart

1) Enable nfs
echo nfs_server_enable="YES" >> /etc/rc.conf

For NFSv4 you will also need the following:

echo nfsv4_server_enable="YES" >> /etc/rc.conf (To enable NFSv4)
echo nfsuserd_enable="YES" >> /etc/rc.conf (The NFS user/group info needed for v4)

2) Create directories and export them

# mkdir -p /mnt/{dir1,dir2}
# vi /etc/exports

(add the following lines to the /etc/exports file)

/mnt/dir1  -alldirs  192.168.1.x/24
/mnt/dir2  -alldirs  192.168.1.x/24

3) restart nfsd either using /etc/rc.d/nfsd restart or service nfsd restart

See The section of the FreeBSD handbook dealing with NFS for more information.
