VNX NFS - Timeout during mount

Question

Hello Folks,

I've created a file system, mounted, exported, nfs server is running. I can ping from the server_2 to client and vice versa

When I try to mount I am getting time outs. I dont want secnfs or v4. I am only trying to do nfsv3

I am running RHEL6.5 on the client side.

[nasadmin@vmgvnx01-p ~]$ server_version ALL

server_2 : Product: EMC File Server Version: T7.1.65.8

server_3 : Product: EMC File Server Version: T7.1.65.8

[nasadmin@vmgvnx01-p ~]$ server_export ALL

server_2 :

export "/vmg-nfs-01" rw=* root=* access=*

export "/" anon=0 access=128.221.252.100:128.221.253.100:128.221.252.101:128.221.253.101

server_3 : no entries

[nasadmin@vmgvnx01-p ~]$ server_mount ALL

server_2 :

root_fs_2 on / uxfs,perm,rw

root_fs_common on /.etc_common uxfs,perm,ro

vmg-nfs-01 on /vmg-nfs-01 uxfs,perm,rw

server_3 :

root_fs_3 on / uxfs,perm,rw,

root_fs_common on /.etc_common uxfs,perm,ro,

Any idea whats going on?

check firewalls, routes

ravi_g · Answer

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

bergec · Answer

You should not use '' in the export options (rw= etc...) Use IP addresses or subnets Claude

Rainer_EMC · Answer

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 ?

VivekSoni · Answer

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.
