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
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 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.
