corosync-qnetd-tool - corosync-qnetd control interface.
corosync-qnetd-tool [-Hhlsv] [-c cluster_name] [-p qnetd_ipc_socket_path]
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.
- -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.
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.
