Issue/Introduction
VM Creation task fails with the following error
"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
There are numerous 'RPC to DOM op create returned: No connection' error messages in the vmkwarning.log, and many events stating 'DOMOwnerUnsubscribeClusterEncrState:5925: DOM Owner on xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx received premature cluster encryption state unsubscription' in the vmkernel.log.
In this case, we identified a combination of fault domain misconfiguration and a network driver issue that caused the VM creation failure
Resolution
We deleted the existing fault domains and created four new fault domains that were in line with the vSAN RAID 5 storage policy.
Each host was placed in vSAN maintenance mode, and the old icen driver was updated to the latest version (icen version 1.15.2.0-1OEM).

After updating, the vSAN node was rebooted and then exited the vSAN maintenance mode, and the same process was followed for other vSAN nodes too.
After completing above tasks, the vSAN VM creation issue was resolved.
