nfs stopped working!

[darthwonka]

Clients are giving the following error:

# mount -t nfs 10.1.0.16:/share/nethome /data/nethome
# mount: 10.1.0.16:/share/nethome failed, reason given by server: Permission denied

We tried rebooting the NAS device and the client.. Same error.
Nothing on the web interface jumps out as a problem. Any suggestions?

[darthwonka]

okay.. the NFS check boxes mysteriously turned off. And they didn't turn back on after reboot.

So is this working?

If NFS on the Server is enabled and clients are not able to successfully logon - here is some items to check to mounting nfs.

Please enter these command from client side:
1. rpcinfo -p IP_of_nfsserver
You should see a list that contain : portmapper, nfs, mountd,nlockmgr, status

2. showmount -e IP_of_nfsserver you should see a list of NFS shares
II. check if your ip address has sufficient right to enter chosen share
III. If above commands give a positive output, please use this mount options:

mount -t nfs -o tcp, rsize=1500, wsize=1500
IP_of_nfsserver:/share/SHARE_NAME

IV. It could be a firewall on client side, for check it out, please turn off firewall.
