resolved – fsinfo ERROR: Stale NFS file handle POST

May 15th, 2014

Today when I tried mount NFS share from one NFS server, it timeout with "mount.nfs: Connection timed out".

I tried to search something in /var/log/messages but no useful info there was found. So I used tcpdump on NFS client:

[root@dcs-hm1-qa132 ~]# tcpdump -nn -vvv host 10.120.33.90 #server is 10.120.33.90, client is 10.120.33.130

The reason of "ERROR: Stale NFS file handle POST" may caused by the following reasons:

1.The NFS server is no longer available
2.Something in the network is blocking
3.In a cluster during failover of NFS resource the major & minor numbers on the secondary server taking over is different from that of the primary.

To resolve the issue, you can try bounce NFS service on NFS server using /etc/init.d/nfs restart.

Good Luck!
