recovery log

A file that maintains a history of all of the transactions affecting the cluster database on all nodes. The recovery log is stored on the cluster's quorum resource and is also referred to as the quorum log.

resource

A physical or logical entity that is capable of being owned by a node, brought online and taken offline, moved between nodes, and managed as a cluster object. A resource can be owned by only a single node at any point in time. A resource is an instance of a resource type.

Resource API

Subset of Failover Cluster API functions that allow a resource DLL to communicate with a Resource Monitor. Some of the functions are implemented by a resource DLL and others are implemented by the Resource Monitor.

resource class

Numeric value that is used to identify failover cluster resources of similar capability, such as resources that can act as storage devices.

resource DLL

Dynamic-link library containing an implementation of the Resource API for a specific type of resource. The resource DLL is loaded into the address space of its Resource Monitor.

Resource Manager

Software component in the Cluster service that works with the Failover Manager to manage resources and groups and initiate failover operations.

Resource Monitor

Component of the Cluster service that manages communication between a node's Cluster service and one or more of its resources.

resource type

A cluster object used to categorize and manage resources sharing similar characteristics. A resource type is implemented in a resource DLL that manages all the resources of that type in the cluster.

rolling upgrade

The process of systematically upgrading each server cluster node while the other nodes continue to provide service. Administrators perform rolling upgrades by failing over all groups on a node, taking the node offline, upgrading the node, bringing it back online, failing back the groups to the node, and continuing to the next node.
