NAMEcorosync-qdevice-tool - corosync-qdevice control interface.
SYNOPSIScorosync-qdevice-tool [-Hhsv] [-p qdevice_ipc_socket_path]
DESCRIPTIONcorosync-qdevice-tool is a frontend to the internal corosync-qdevice IPC. Its main purpose is to show important information about the current internal state of corosync-qdevice.
OPTIONS-H Properly shutdown the corosync-qdevice process -h Display a short usage text -s Display the status of the corosync-qdevice process. The output is described in its own section below. -v Display more verbose output for the -s option. -p Path to the corosync-qdevice communication socket.
STATUS COMMAND OUTPUTQdevice information ------------------- Model: Net Node ID: 1 HB interval: 10000ms Sync HB interval: 30000ms Configured node list: 0 Node ID = 1 Heuristics: Enabled Ring ID: 1.a00000000021b48 Membership node list: 1 Quorate: Yes Quorum node list: 0 Node ID = 1, State = member Expected votes: 2 Last poll call: 2016-06-24T17:05:20 (cast vote) Qdevice-net information ---------------------- Cluster name: Cluster QNetd host: localhost:5403 Connect timeout: 8000ms HB interval: 8000ms VQ vote timer interval: 5000ms TLS: Supported Algorithm: Fifty-Fifty split Tie-breaker: Node with lowest node ID Poll timer running: Yes (cast vote) State: Connected Heuristics result: Pass (regular: Pass, membership: Fail, connect: Fail) TLS active: Yes (client certificate sent) Connected since: 2016-06-24T17:02:35 Echo reply received: 2016-06-24T17:05:15 The output is split into a generic qdevice section and a model specific section. Most of the items are just taken from corosync.conf file. It's helpful to note that the Membership node list is the membership list of the current node and should match the quorum node list. Last poll call is the timestamp (in iso format) of the last call to the votequo‐ rum_qdevice_poll function. For model net, it's good to check the Poll timer running state. Internally, model net sup‐ ports 3 states. Not voting (when Poll timer running is No, which means corosync-qdevice is waiting for corosync-qnetd to reply), voting (without cast vote, it means that the corosync-qnetd algorithm decides that the current node shouldn't get a vote) and voting (with cast vote).
