13 corosync-cfgtool A tool for displaying and configuring active parame‐
14 ters within corosync.
15
17 -i Finds only information about the specified interface IP address
18 with -s.
19
20 -s Displays the status of the current links on this node for
21 UDP/UDPU, while extended status for KNET. If any interfaces are
22 faulty, 1 is returned by the binary. If all interfaces are
23 active 0 is returned to the shell. After each link, the nodes
24 on that link are displayed in order with their status, for exam‐
25 ple there are 3 nodes with KNET transportation: LINK ID 0:
26 id = 192.168.100.80
27 status:
28 node 0: link enabled: 1 link connected: 1
29 node 1: link enabled: 1 link connected: 1
30 node 2: link enabled: 1 link connected: 1
31
32 -b Displays the brief status of the current links on this node
33 (KNET only) when used with "-s". If any interfaces are faulty, 1
34 is returned by the binary. If all interfaces are active 0 is
35 returned to the shell. After each link, the nodes on that link
36 are displayed in order with their status encoded into a single
37 digit. 1=link enabled, 2=link connected, So a 3 in a node posi‐
38 tion indicates that the link is both enabled and connected. The
39 local link (which will only ever be enabled on link 0) shows as
40 enabled but not connected for internal reasons. The output will
41 be: LINK ID 0:
42 id = 192.168.100.80
43 status = 333
44
45 -R Tell all instances of corosync in this cluster to reload
46 corosync.conf.
47
48 -L Tell corosync to reopen all logging files. In contrast to other
49 subcommands, nothing is displayed on terminal if call is suc‐
50 cessful.
51
52 -k Kill a node identified by node id.
53
54 -a Display the IP address(es) of a node.
55
56 -h Print basic usage.
57
58 -H Shutdown corosync cleanly on this node.
