CVMCluster Agent

Table 5-9 provides a description of the CFSCluster agent.

    CVMCluster Agent

Description

Controls node membership on the cluster port associated with CVM. The CVMCluster resource requires the CVMMultiNIC resource and must be configured to depend on CVMMultiNIC. The CVMCluster agent executable is /opt/VRTSvcs/bin/CVMCluster/CVMClusterAgent. The type definition is in the file /etc/VRTSvcs/conf/config/CVMTypes.cf. The configuration is added to the main.cf file after running the cfscluster config command. 

Entry Points

  • Online—Joins a node to the CVM cluster port.
  • Offline—Removes a node from the CVM cluster port.
  • Monitor—Monitors the node's CVM cluster membership state.
  • Clean—A null operation for a cluster file system mount.
