NFS Datastore Inaccessible after Reboot – How to Fix

NFS datastores can be described as an easy way to store data on VMware ESXi hosts. However, sometimes NFS datastores become inaccessible after an ESXi host reboot. This stops us from accessing our data.

Some of the common reasons why an NFS datastore becomes inaccessible after an ESXi host reboot include:

• Network configuration issues
• Misconfiguration of the NFS server or ESXi host
• Problems with the NFS server

Troubleshooting Tips

1. First, we have to verify that the ESXi host has the correct network configuration, including IP address, subnet mask, default gateway, and DNS settings after a reboot.
2. Next, verify that the NFS server hosting the datastore is up and running after the reboot. We also have to check the NFS service is active and functioning correctly by checking the NFS server’s logs or console for any errors or issues.
3. Then, it is time to review the NFS server’s configuration to ensure that it allows connections from the ESXi host. We have to verify that the ESXi host’s IP address or hostname is listed as an allowed client on the NFS server.
4. Now, we have to check the ESXi host’s auto-mount settings to ensure that the NFS datastore is set to automatically mount after a reboot. According to our experts, we can find these settings in the vSphere Web Client by heading to Configuration > Storage > NFS.
5. We also have to check that the NFS share has the correct permissions configured to allow the ESXi host to access it. We can check this by heading to the NFS server’s configuration.
6. In some cases, firewall rules or security settings on the ESXi host, NFS server, or any intermediate network devices may block the NFS communication.
7. Our experts also recommend checking the mount options used for the NFS datastore on the ESXi host. They have to match the configuration of the NFS server.
8. Verify the NFS version used by both the ESXi host and the NFS server are compatible.
9. Furthermore, we can review the ESXi host’s logs for any error messages or warnings related to the NFS datastore.
10. Finally, test the connectivity to the NFS server from the ESXi host’s console or SSH session using tools like ping or traceroute.
