The clustering resource provides functions to allow a cluster to be created and managed.
- Child Topics
- Clustering object model
The object model describing this resource contains the following objects.
- Get quorum device list
Get a list of available quorum devices that are visible to the cluster. This list is the quorum devices that could be used when converting a HNAS gateway system from a single node into a cluster.
- Get quorum device
Get the quorum device that is used by the current cluster.
- Set quorum device
Set the quorum device that is used by the current cluster. For a cluster to be robust, it must have a quorum device, without a quorum device, it is considered degraded.
- Delete quorum device
Deletes the current quorum device that is being used by the cluster. Once the quorum device is deleted, the cluster will be considered degraded and should have a new quorum device configured as soon as possible.
- Delete a cluster node
A cluster is made up from multiple nodes, and a quorum device. If a node is no longer needed as part of a cluster, it can be deleted. Once deleted, the node will revert to a default configuration and will need to be reconfigured manually.
- Rename a cluster node
Change the name of a cluster node.
- Upgrade to a cluster
When first configured, an HNAS gateway system is a standalone system. To improve resilience, nodes can be combined into a cluster. Upgrading to a cluster involves assigning a cluster name, and a quorum device.
- Join an existing cluster
Add a standalone gateway node to an existing cluster. To join a cluster, a node needs to have a node IP address configured in addition to a management IP address. The useAdminVnodeAsPnodeAddress option allows the management address to be used as the node address once the node joins the cluster.
