NAME

kerrighed_nodes - File hosting nodes list and session number of a Kerrighed cluster.

DESCRIPTION

The kerrighed_nodes file contains the list of nodes belonging to the Kerrighed cluster. Each node name is on a separate line and is followed by the logical node number and the name of the network device to use for Kerrighed communications.

The session field contains identifier of the cluster. When several Kerrighed clusters have to share the same Ethernet switch, each cluster should define a different session identifier to avoid collisions. A session identifier is a simple integer.

The nbmin field is used to define the number of nodes to be automatically started when a Kerrighed cluster is booting. This field is optional. When this field is set, the use of the krgadm is not needed any more. During the boot phase of cluster nodes when the kerrighed module is loaded, Kerrighed waits for "nbmin" nodes to be up. Then the required number of nodes are up, Kerrighed is automatically started.

Example 1. kerrighed_nodes

         session=1
         nbmin=4
         node1:0:eth0
         node2:1:eth0
         node3:2:eth0
         node4:3:eth0
       
 

The default location for the kerrighed_nodes file is the /etc/kerrighed/ directory.
