NFS not work ?

[5m1l3]

I have two FreeNAS boxes with 9.2.1.7. Boxes clear installed. (not upgraded)
And i cant mount this nfs from ubuntu (12.04 and 14.04), rpcbind and nfsd at server started.
When i try to mount it:

mount -t nfs 192.168.110.251:/mnt/safe1 /mnt/net
It's just hangup for long time, and after it show mount timeout.

When i do showmount -e 192.168.110.251 (my freenas box)
it hangup for long time, but give me exports list:

root@nfsclient:~# showmount -e 192.168.110.251
Export list for 192.168.110.251:
/mnt/safe1 192.168.110.0

If i from this client try mount another nfs share from test linux box, everything work fine and fast. All boxes in one subnet, all firewalls disabled. I tried to add host name to hosts file for server and client.

Help, help!!! :(

Can somebody help??

 

[Joshua Parker Ruehlig]

I know one thing that helped me on a direct link NFS connection was adding a host entry for my NFS client machine on freenas. not sure if that helps you

 

[5m1l3]

I tried this already, and this not help =-(

 

[5m1l3]

It was a firmware trouble with Cisco SG200-08 switch. Solution downgrade firmware to 1.0.5.1. In any firmware greater than 1.0.5.1 NFS not work, cisco dont resolve trouble.

 

[Havoc70]

How did you downgrade the firmware? I'm having this exact same problem, exact same switches. Though I'm on this version of firmware and still having this problem. Guess I'll try a different switch.
