Persisting High Availability Protection State for Virtual Machines Stored on Distributed Object-Based Storage |
摘要 |
Techniques are disclosed for persisting high availability (HA) protection state for virtual machines (VMs) running on host systems of a host cluster, where the host cluster aggregates locally-attached storage resources of the host systems to provide an object store, and where persistent data for the VMs is stored as per-VM storage objects across the locally-attached storage resources comprising the object store. In one embodiment, a host system in the host cluster executing a HA module determines an identity of a VM that has been powered-on in the host cluster. The host system then persists HA protection state for the VM in a storage object of the VM, where the HA protection state indicates that the VM should be restarted on an active host system in the case of a failure in the host cluster. |

1. A method for persisting high availability (HA) protection state for virtual machines (VMs) running on host systems of a host cluster, wherein the host cluster aggregates locally-attached storage resources of the host systems to provide an object store, and wherein persistent data for the VMs is stored as per-VM storage objects across the locally-attached storage resources comprising the object store, the method comprising:
determining, by a first host system in the host cluster executing a first HA module, an identity of a VM that has been powered-on in the host cluster; and persisting, by the first host system, HA protection state for the VM in a storage object of the VM, the HA protection state indicating that the VM should be restarted on an active host system in case of a failure in the host cluster. |
