Enable NFS v4 on NAS4Free v9.1
By default NAS4Free has NFS 4 support as provided by FreeBSD 9.1 but it is not enabled. This forum post describes how to enable it.
The NFS mountd is run as follows:
/usr/sbin/mountd -r /etc/exports /etc/zfs/exports
with both /etc/exports and /etc/zfs/exports listed. It is assumed that the /etc/exports file will be overwritten by the web UI when configuration changes are made, so changes are added to the /etc/zfs/exports file in the hope that they will be left undisturbed.
The following must be added to the /etc/zfs/exports file:
V4: /
Procedure
rc.conf
Add the following three variables to the rc.conf page. From the System menu, select Advanced then move to the rc.conf tab:
| Variable | Value |
|---|---|
| nfsv_server_enable | YES |
| nfsv4_server_enable |
YES |
| nfsuserd_enable | YES |
Command scripts
Add the following command script to the Command scripts tab. From the System menu, select Advanced then move to the Command scripts tab:
| Command | Type |
|---|---|
| echo "V4: /" >> /etc/zfs/exports |
PreInit |
Residuals
- consider exporting just the zfs datasets with a export root of "V4: /mnt/tank"
- work out how to get IPv6 NFS exports working
