corosync-qnetd-tool - corosync-qnetd control interface.
corosync-qnetd-tool [-Hhlsv] [-c cluster_name] [-p qnetd_ipc_socket_path]
is a frontend to the internal corosync-qnetd IPC. Its
main purpose is to show important information about the current internal state
- Properly shutdown the corosync-qnetd process
- Display a short usage text
- List all clients connected to the corosync-qnetd
process. The output is described in its own section below.
- Display status of the corosync-qnetd process.
- Display more verbose output for options -l and
- 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
- Path to the corosync-qnetd communication socket.
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
as configured in the
corosync.conf file. Information about nodes follows. Client address
the IP address and port of the client. HB interval
is the heartbeat
interval between corosync-qnetd
This option can be configured in corosync.conf. Configured node list
the list of nodes configured in corosync.conf. Ring ID
Membership node list
are self-explanatory. TLS active
if an encrypted transport is used between server and client. Vote
last vote sent to corosync-qdevice
client. The last ACK/NACK vote (if
it exists) is in parentheses.
