[Users] Attach nfs domain to gluster dc

[Juan Pablo Lorier]

Hi Dan,

After reading other posts on this matter in the list these days, I've
manually corrected the firewall configuration to allow v3 to work (don't
know if everyone is needed):

# nfs
-A INPUT -p tcp -m tcp --dport 111   -j ACCEPT
-A INPUT -p tcp -m tcp --dport 38467 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 2049  -j ACCEPT
-A INPUT -p udp -m udp --dport 2049  -j ACCEPT
-A INPUT -p udp -m udp --dport 41729  -j ACCEPT
-A INPUT -p tcp -m tcp --dport 48491  -j ACCEPT
-A INPUT -p udp -m udp --dport 43828  -j ACCEPT
-A INPUT -p tcp -m tcp --dport 48491  -j ACCEPT
-A INPUT -p udp -m udp --dport 47492  -j ACCEPT
-A INPUT -p tcp -m tcp --dport 58837  -j ACCEPT

Now I'm changing the settings by overriding the defaults in the domain
and auto negotiating the protocol. This firewall correction may be a
good thing to add in the deploy.
Regards,
