NFS Timeout Issue on 7-Mode VFiler

[SEENIKANNAN]

Hi,

I having following issue while am trying to mount the NFS share on host,

# mount -v -t nfs nfstesting:/vol/vol0/nfstest  /nfstesting

mount: trying 10.10.30.1 prog 100003 vers 3 prot tcp port 2049

mount: trying 10.10.30.1 prog 100005 vers 3 prot udp port 4046

mount: mount to NFS server 'nfstesting' failed: timed out (retrying).

mount: trying 10.10.30.1 prog 100003 vers 3 prot tcp port 2049

mount: trying 10.10.30.1 prog 100005 vers 3 prot udp port 4046

mount: mount to NFS server 'nfstesting' failed: timed out (retrying).

Would like to know why it's getting timed out even all ports are opened no firewall issue.

Data ONTAP 7 Mode:
111   TCP/UDP portmapper
2049 TCP/UDP nfsd
4046 TCP/UDP mountd
4045 TCP/UDP nlockmgr
4047 TCP/UDP status

Can someone help on this with the troubleshooting?

Regards,

Hi Seenikannan,

Please find some of the troubleshooting steps that we can do to identify the issue:
1) Check license and make sure NFS license is added.
> license show

2) Check If NFS service is running on NetApp and start it if not started.
> nfs status
NFS server is running.

3) From client can we do rpcinfo -p <netapp_interface_ip> and check if we see like shown below :
# rpcinfo -p 10.216.41.183
program vers proto port service
100003 4 tcp 2049 nfs
100011 1 udp 4049 rquotad
100024 1 tcp 4047 status
100024 1 udp 4047 status
100021 4 tcp 4045 nlockmgr
100021 3 tcp 4045 nlockmgr
100021 1 tcp 4045 nlockmgr
100021 4 udp 4045 nlockmgr
100021 3 udp 4045 nlockmgr
100021 1 udp 4045 nlockmgr
100005 3 tcp 4046 mountd
100003 3 tcp 2049 nfs
100005 2 tcp 4046 mountd
100005 1 tcp 4046 mountd
100003 2 tcp 2049 nfs
100005 3 udp 4046 mountd
100003 3 udp 2049 nfs
100005 2 udp 4046 mountd
100005 1 udp 4046 mountd
100003 2 udp 2049 nfs
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper

4) Check /etc/exports have the client IP that is trying to mount is allowed in root hosts list.

>rdfile /etc/exports

>exportfs 

5) You can set the below option and check what ONTAP is reporting when client is trying to mount the exports
> options nfs.mountd.trace on

If the above trouble hooting doesn't help , i would suggest to capture the o/p and open a support ticket.
