My installation does not have ocf-tester, There is a program called
ocft with a test option. Not sure if this is a suitable replacement.
If not, how could I get
the ocf-tester program? I ran the ocft program and get the following
output. Not sure what it means.
[root@h2 ovs]# ocft test -n test-ovndb -o master_ip 10.0.0.1
/usr/share/openvswitch/scripts/ovndb-servers.ocf
ERROR: cases directory not found.
I have attached ocf-tester with this mail. I guess it's a standalone
script. If it does not work, I think it's better not to attempt anymore
as we have another way to find out.
Alternately, you can check if the ovsdb servers are started
properly by running
/usr/share/openvswitch/scripts/ovn-ctl --db-sb-sync-from=10.0.0.1
--db-nb-sync-from=10.0.0.1 start_ovsdb
The output are as follows. Should we use --db-sb-sync-from-addr instead?
[root@h2 ovs]# /usr/share/openvswitch/scripts/ovn-ctl
--db-sb-sync-from=10.0.0.1 --db-nb-sync-from=10.0.0.1 start_ovsdb
/usr/share/openvswitch/scripts/ovn-ctl: unknown option
"--db-sb-sync-from=10.0.0.1" (use --help for help)
/usr/share/openvswitch/scripts/ovn-ctl: unknown option
"--db-nb-sync-from=10.0.0.1" (use --help for help)
'ovn-ctl' runs without any error message after I fixed the command
line parameter.
I am sorry for the misinformation, Andy. What you ran is correct. Could
you check the status of the ovsdb servers in h2 after you run the above
command using the following commands.
ovn-ctl status_ovnnb
ovn-ctl status_ovnsb
Both the above commands should return "running/backup". If you see in
the OCF script in the function ovsdb_server_start(), we wait
indefinitely till the DB servers are started. Since the 'start' action
on h2 times out, I doubt that the servers are not started properly.
I think this is mostly due to the crm configuration. Once you add
the 'ms' and 'colocation' resources, you should be able to
overcome this problem.
No, ovndb still failed to launch on h2.

I have never tried colocating two resources with the ClusterIP
resource. Just for testing, is it possible to drop the WebServer
resource?
Done. It did not make any difference that I can see.
