COROSYNC-QNETD-TOOL(8)

NAME
corosync-qnetd-tool - corosync-qnetd control interface.

SYNOPSIS
corosync-qnetd-tool [-Hhlsv] [-c cluster_name] [-p qnetd_ipc_socket_path]

DESCRIPTION
corosync-qnetd-tool is a frontend to the internal corosync-qnetd IPC. Its main purpose is to show important information about the current internal state of corosync-qnetd.

OPTIONS

-H  Properly shutdown the corosync-qnetd process

-h  Display a short usage text

-l  List all clients connected to the corosync-qnetd process. The output is described in its own section below.

-s  Display status of the corosync-qnetd process.

-v  Display more verbose output for options -l and -s

-c  Used only with the -l option. By default, information about all clients from all clusters is displayed, with this option it's possible to filter information from a single cluster given the cluster_name.

-p  Path to the corosync-qnetd communication socket.

LIST COMMAND OUTPUT
Cluster "Cluster":
    Algorithm:          Fifty-Fifty split (KAP Tie-breaker)
    Tie-breaker:        Node with lowest node ID
    Node ID 1:
        Client address:         ::ffff:127.0.0.1:52000
        HB interval:            8000ms
        Configured node list:   1, 2
        Ring ID:                1.a00000000021b40
        Membership node list:   1, 2
        TLS active:             Yes (client certificate verified)
        Vote:                   No change (ACK)
 ...
The output contains a list of clusters. Each cluster has the cluster common options Algorithm (optionally with Keep Active Partition Tie Breaker information) and Tie-breaker as configured in the corosync.conf file. Information about nodes follows. Client address is the IP address and port of the client. HB interval is the heartbeat interval between corosync-qnetd and corosync-qdevice client. This interval depends on the timeout option that can be set in the corosync.conf file. Configured node list is the list of nodes configured in corosync.conf. Ring ID and Membership node list are self-explanatory. TLS active describes if an encrypted transport is used between server and client. Vote is last vote sent to corosync-qdevice client. The last ACK/NACK vote (if it exists) is in parentheses.
