4.2 Main CF table

When the GUI is first started, or after the successful completion of the configuration wizard, the main CF table will be displayed in the right panel. A tree showing the cluster nodes will be displayed in the left panel (see "Figure 4.4 Cluster Admin main window.")

The tree displays the local state of each node, but does not give information about how that node considers other nodes. If two or more nodes disagree about the state of a node, one or more colored exclamation marks appear next to the node. Each exclamation mark represents the node state of which another node considers that node to be.

The table in the right panel is called the main CF table. The column on the left of the table lists the CF states of each node of the cluster as seen by the other nodes in the cluster. For instance, the cell in the second row and first column is the state of fuji3 as seen by the node fuji2.

There is an option at the bottom of the table to toggle the display of the state names. This is on by default. If this option is turned off, and there is a large number of nodes in the cluster, the table will display the node names vertically to allow a larger number of nodes to be seen.

There are two types of CF states:

Local states are the states a node can consider itself in.
Remote states are the states a node can consider another node to be in.

The following table lists these various states.

Table 4.1 Local states
CF state		Description
UNLOADED		The node does not have a CF driver loaded.
LOADED		The node has a CF driver loaded, but is not running.
COMINGUP		The node is in the process of starting and should be UP soon.
UP		The node is up and running normally.
INVALID		The node has an invalid configuration and must be reconfigured.
UNKNOWN		The GUI has no information from this node. This can be temporary, but if it persists, it probably means the GUI cannot contact that node.
UNCONFIGURED		The CF driver is loaded but the node is not yet configured to run CF.

The following table lists the remote states.

Table 4.2 Remote states
CF state		Description
UP		The node is up and part of this cluster.
DOWN		The node is down and not in the cluster.
UNKNOWN		The reporting node has no opinion on the reported node.
LEFTCLUSTER		The node has left the cluster unexpectedly, probably from a crash. To ensure cluster integrity, it will not be allowed to rejoin until marked DOWN.
