"Failed to connect to owner host xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx". Failed to create object error observed during the creation of virtual machine in vSAN cluster .

Products

• VMware vSphere ESXi

Issue/Introduction

Symptoms:

• The following error appears in vCenter when attempting to create a virtual machine within a vSAN cluster.Cannot complete file creation operation. Failed to connect to owner host xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. Failed to create object. Reserving folder on host.

                  

Environment

• VMware vSAN 7.x
• VMware vSAN 8.x

Cause

• Hosts in the vSAN cluster experience 100% packet loss over the vSAN network due to incorrect or unsupported jumbo frame (MTU 9000) configuration in the network path.

         

Resolution

• As a workaround change the MTU setting to 1500 on the vSAN network to allow successful host communication and virtual machine creation.
• Engage the Physical Network Team to set the MTU (Maximum Transmission Unit) to 9000 on the network. This is required to ensure proper communication between the vSAN cluster hosts.
