SYSTEM AND METHOD FOR HANDLING MULTI-NODE FAILURES IN A DISASTER RECOVERY CLUSTER |
| 摘要 |
A system and method for handling multi-node failures in a disaster recovery cluster is provided. In the event of an error condition, a switchover operation occurs from the failed nodes to one or more surviving nodes. Data stored in non-volatile random access memory is recovered by the surviving nodes to bring storage objects, e.g., disks, aggregates and/or volumes into a consistent state. |

1. A method comprising:
determining that a candidate node is not available for a switchover operation; identifying an alternate node for the switchover operation; determining whether the identified alternate node is capable of handling a load from a plurality of other nodes; in response to determining that the identified alternate node is capable of handling the local from the plurality of other nodes, performing a switchover operation to transfer ownership of one or more objects from the plurality of other nodes to the identified alternate node; and recovering data from a non-volatile memory to the one or more objects; and bringing online the one or more objects. |
