Connectivity to the NFS server is lost

Products

• VMware vCenter Server
• VMware vSphere ESXi

Issue/Introduction

Summary

The event indicates that the ESX host has lost connectivity to the NFS server.

Example

If an NFS volume nfs-share is mounted from host nfs-server:/share, then the following message is displayed if connectivity to the NFS server is lost:

Lost connection to server nfs-server mount point /share, mounted as 1264e433-5854ee53-0000-000000000000 ("nfs-share")

Impact

The NFS volume (and virtual machines residing in the affected volume) are unavailable to the ESX host.

Environment

VMware ESX 4.0.x
VMware vCenter Server 4.0.x

Resolution

Check the networking configuration to make sure that the ESX host can still connect to the NFS server. You can verify whether the NFS server is reachable by logging in to the service console and pinging the NFS server using vmkping:

# vmkping <NFS server>

After connectivity to the NFS server is restored, the volume automatically reconnects, and all virtual machines residing in the affected volume are available again.
