NAME
clinfo - display cluster information SYNOPSIS
clinfo [-nh] DESCRIPTION
The clinfo command displays cluster configuration information about the node from which the command is executed. Without arguments, clinfo returns an exit status of 0 if the node is configured and booted as part of a cluster. Otherwise, clinfo returns an exit status of 1. OPTIONS
The following options are supported: -h Displays the highest node number allowed to be configured. This is different from the maximum number of nodes supported in a given cluster. The current highest configured node number can change immediately after the command returns since new nodes can be dynami- cally added to a running cluster. For example, clinfo -h might return 64, meaning that the highest number you can use to identify a node is 64. See the Sun Cluster 3.0 System Administration Guide for a description of utilities you can use to determine the number of nodes in a cluster. -n Prints the number of the node from which clinfo is executed. EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 An error occurred. This is usually because the node is not configured or booted as part of a cluster. ATTRIBUTES

VOTEQUORUM_LEAVING(3)				    Corosync Cluster Engine Programmer's Manual 			     VOTEQUORUM_LEAVING(3)

NAME
votequorum_leaving - Tell other nodes that we are leaving the cluster SYNOPSIS
#include <corosync/votequorum.h> int votequorum_leaving(votequorum_handle_t handle); DESCRIPTION
The votequorum_leaving function is used to tell the other nodes in the cluster that this node is leaving. They will (when the node actually leaves) reduce quorum to keep the cluster running without this node. This function should only be called if it is known that the node is being shut down for a known reason and could be out of the cluster for an extended period of time. Normal behaviour is for the cluster to reduce the total number of votes, but NOT expected_votes when a node leave the cluster, so the clus- ter could become inquorate. This is correct behaviour and is ther eto prevent split-brain. Do NOT call this function unless you know what you are doing. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS
The errors are undocumented. SEE ALSO
