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
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.
