check firewalls, routes

Yeah, I already checked the firewalls and routes. the VNX and the RHEL client are in the same LAN.

I enabled debug param for nfs to 7 but do not see any thing in the log. where is the debug log located? Though I am having persistent DNS errors as in the lab I cannot connect to DNS. I also added the client and pushed the hosts file on server_2

At this point I am trying to re-init everything (is there a KB for this) as it is a new setup

Take a network trace

You should not use "" in the export options (rw= etc...)

Use IP addresses or subnets

Claude is right – an asterix wildcard (*) is not a valid syntax for exporting a NFS share

Please check the VNX NFS manual or at least take a look at “man server_export”

What does a “showmount –e ” issued from your NFS client report ?

True, if you need all the users in the network to access the export, just export without mentioning the IPs. It should look something like the following from your VNX/Celerra CLI:

# server_export server_2 -P nfs /NFS

# server_export server_2

server_2 :

export "/NFS"

From the client/host side when you check for the availability of the network export over the interface, it should look like the following:

[root@nfstest ~]# showmount -e xx.xx.xx.xx

Export list for xx.xx.xx.xx:

/NFS                (everyone)

Just go ahead and mount it then.

Hope this helps.
