Chapter 4. Cluster Administration 69
Cluster and service status includes the following information:
• Cluster member system status
• Service status and which cluster system is running the service or owns the service
The following tables describe how to analyze the status information shown by the Cluster
Status Tool and the clustat utility.
Member Status Description
Member The node is part of the cluster.
Note: A node can be a member of a cluster; however, the node
may be inactive and incapable of running services. For example,
if rgmanager is not running on the node, but all other cluster
software components are running in the node, the node appears as
a Member in the Cluster Status Tool. However, without
rgmanager running, the node does not appear in the clustat
display.
Dead The member system is unable to participate as a cluster member.
The most basic cluster software is not running on the node.
Table 4-1. Member Status for the Cluster Status Tool
Member Status Description
Online The node is communicating with other nodes in the cluster.
Inactive The node is unable to communicate with the other nodes in the
cluster. If the node is inactive, clustat does not display the
node. If rgmanager is not running in a node, the node is
inactive.
Note: Although a node is inactive, it may still appear as a
Member in the Cluster Status Tool. However, if the node is
inactive, it is incapable of running services.
