Environment

VMware ESXi 8.0.x

Cause

The messages seen in the issue described above are evidence of lock files in the NFS server.

Resolution

To resolve the locks on the NFS side, please contact your storage vendor.

 

If the VM is still not powering on after the lock issue is mitigated on the storage side, please raise a ticket with VMware by Broadcom.
