Unable to attach the datastore using the NFSv4.1 protocol for ESXi6, ONTAP version cDOT8.2

Unable to attach the datastore using the NFSv4.1 protocol for ESXi6, ONTAP version cDOT8.2

 

I have cluster with two nodes and SVM is enabled with NFSv4 and NFSv4.1 is enabled. Created the volume and a export policy. Now i am trying to add the datastore to the ESXi6.0 using the NFSv4.1. Throws the below error in the vcenter server

An error occurred during host configuration.
Operation failed, diagnostics report: Sysinfo error on operation returned status : Timeout. Please see the VMkernel log for detailed error information

 


Checked the VMkernel log on the ESXi server and below is the snippet.

Could not understand from the log what the problem is. Need help in resolving the issue.

Re: Unable to attach the datastore using the NFSv4.1 protocol for ESXi6, ONTAP version cDOT8.2

Re-create the error and then generate an ASUP with type "all" and PM me the SN/sysid so I can have a look.

 

::> autosupport invoke * -type all

 

If you can get a packet trace during the issue, even better.

 

A few questions:

 

- What is the mount syntax?

- Are you mounting via VSC?

- What data LIF are you trying to mount?

- What volume?

- Does the mount work from regular Linux clients via v4.1 (ie RHEL)?

- Does the mount work via NFSv3 in ESX?

 

Once I have the ASUP I can try to piece together what (if any) config issues you might have and review logs.
