Talk:NFS

I think that /etc/systemd/system/auto_share.service should contain the following line after Description:

After=NetworkManager-wait-online.service
Before=systemd-user-sessions.service

The rationale for this is that you need to wait for the network to be up and running before attempting an NFS connect from client-side. You also need to perform the NFS mountings before making user sessions available, because the latter may be dependent on the former. For example, my bash profile is stored on a remote server, so I need NFS drives mounted before I even attempt a login. On some systems, maybe the whole home directory is on a different computer (as would be the case for thin clients), meaning that they should definitely be mounted before users can log in.

You need to enable NetworkManager-wait-online.service like so:

# systemctl enable NetworkManager-wait-online

I can't help thinking that this is a bit of a kludge in any event, and is a scenario that should be handled automatically by systemd.

/etc/systemd/system/auto_share.service is a bad place to create the file. Instead, do it in the standard way by creating it as /lib/systemd/system/auto_share.service and re-enabling it using the command

# systemctl reenable auto_share.service

Make iptables.rules syntax more clear

For me the file /etc/iptables/iptables.rules didn't exist so I created it with the lines in Firewall configuration section. After that iptables failed to start, giving syntax errors. After some searching, I added "*nat" at top and "COMMIT" at bottom of the file, and it worked. Will adding this info make it more clear or should we leave it way it is? axper (talk) 18:48, 28 September 2013 (UTC)

If /etc/iptables/iptables.rules didn't exist then you didn't use a firewall and there was no need to do any configuration to enable NFS access through a firewall. I don't think we should add too much information about how to configure a firewall in general on the NFS page. I checked the ssh page to see how they address firewalls (ssh was the first thing I could think of that probably needs some firewall configuration) and they use command like

# iptables -I INPUT 1 -p tcp --dport 22 -j ACCEPT

instead of editing iptables.rules. Should we change the article to show commands similar to above rather than talking about /etc/iptables/iptables.rules or should we just keep the one sentence mentioning the port numbers and protocols? Crawlman (talk) 07:24, 18 December 2013 (UTC)

Add "enable rpc-statd.service" in the Mounting From Linux Section

Ensure that rpc.statd, the daemon that listens for reboot notifications from other hosts, is running on the client. If not, start it with:

# systemctl start rpc-statd.service

and for future reboots, enable it with:

# systemctl enable rpc-statd.service

This avoids the error message:

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

Add a new note below

Note: Server name needs to be a valid hostname (not just IP address). Otherwise mounting of remote share will hang.

Suggested:

Note: Not all servers run the same NFS package. For example, Debian Squeeze will reject mount -t nfs4, but it accepts mount -t nfs. Check man mount for the full list of options.
