NOTE:
AppleTalk is not supported on clustered disk resources. AppleTalk requires local memory for volume indexing. On failover events, the memory map is lost and data corruption can occur.
Cluster groups and resources, including file shares
The Failover Cluster Management tool (Start > Administrative Tools > Failover Cluster Management) provides complete online help for all cluster administration activities.
Cluster resources include administrative types of resources as well as file shares. The following sections include overview and planning issues for cluster groups, cluster resources, and clustered file shares.
Creating and managing these resources and groups must be managed through Failover Cluster Management.
Cluster group overview
A default cluster group is automatically created when the cluster is first created. This default cluster group contains an Internet Protocol (IP) Address resource, a Network Name resource, and the Quorum disk resource. When the new cluster is created, the (IP) address and the cluster name that were specified during setup are set up as the IP address and network name of this default cluster group.
CAUTION:
Do not delete or rename the Cluster Group or IP Address. Doing so results in losing the cluster and requires reinstallation of the cluster.
When creating groups, the administrator's first priority is to gain an understanding of how to manage the groups and their resources. Administrators may choose to create a resource group and a virtual server for each node that will contain all resources owned by that node, or the administrator may choose to create a resource group and virtual server for each physical disk resource. Additionally, the administrator should try to balance the load of the groups and their resources on the cluster between the nodes.
Node-based cluster groups
Creating one resource group and one virtual server for each node facilitates group and resource administration. This setup allows administrators to include all file share resources under one group. Clients access all of the resources owned by one node through a virtual server name.
