NAME

6       corosync-qnetd-tool - corosync-qnetd control interface.
7

SYNOPSIS

9       corosync-qnetd-tool       [-Hhlsv]      [-c      cluster_name]      [-p
10       qnetd_ipc_socket_path]
11

DESCRIPTION

13       corosync-qnetd-tool is a frontend to the internal  corosync-qnetd  IPC.
14       Its  main  purpose  is  to show important information about the current
15       internal state of corosync-qnetd.
16

OPTIONS

18       -H     Properly shutdown the corosync-qnetd process
19
20       -h     Display a short usage text
21
22       -l     List all clients connected to the  corosync-qnetd  process.  The
23              output is described in its own section below.
24
25       -s     Display status of the corosync-qnetd process.
26
27       -v     Display more verbose output for options -l and -s
28
29       -c     Used  only with the -l option. By default, information about all
30              clients from all clusters is displayed, with  this  option  it's
31              possible  to  filter information from a single cluster given the
32              cluster_name.
33
34       -p     Path to the corosync-qnetd communication socket.

LIST COMMAND OUTPUT

38       Cluster "Cluster":
39           Algorithm:          Fifty-Fifty split (KAP Tie-breaker)
40           Tie-breaker:        Node with lowest node ID
41           Node ID 1:
42               Client address:         ::ffff:127.0.0.1:52000
43               HB interval:            8000ms
44               Configured node list:   1, 2
45               Ring ID:                1.a00000000021b40
46               Membership node list:   1, 2
47               TLS active:             Yes (client certificate verified)
48               Vote:                   No change (ACK)
49        ...
50
51       The output contains a list of clusters. Each cluster  has  the  cluster
52       common  options  Algorithm  (optionally  with Keep Active Partition Tie
53       Breaker information) and Tie-breaker as configured in the corosync.conf
54       file.  Information  about  nodes  follows.   Client  address  is the IP
55       address and port of the client.  HB interval is the heartbeat  interval
56       between  corosync-qnetd and corosync-qdevice client. This option can be
57       configured in corosync.conf.  Configured node list is the list of nodes
58       configured  in  corosync.conf.   Ring  ID  and Membership node list are
59       self-explanatory.  TLS active describes if an  encrypted  transport  is
60       used  between  server  and client.  Vote is last vote sent to corosync-
61       qdevice client. The last ACK/NACK vote (if it exists) is  in  parenthe‐
62       ses.
