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 option can be
       configured  in  corosync.conf.   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.
