PCS/Corosync cluster via pcs CLI
Hi everybody,
sorry for the late response but I was on PTO. I don't understand the
meaning of the cleanup commands, but maybe it's just because I'm not
getting the whole picture.
I have to confirm that fault was mine PCS CLI is working on
TripeO QuickStart
but requires pcs cluster restart on particular node which went down
via ` nova stop controller-X` and was brought up via `nova start controller-X`
Details here :-
http://bderzhavets.blogspot.ru/2016/08/emulation-rdo-triple0-quickstart-h...
VENV been set up with instack-virt-setup doesn't require ( on bounced Controller node
)
# pcs cluster stop
# pcs cluster start
Before issuing start.sh
#!/bash -x
pcs resource cleanup rabbitmq-clone ;
sleep 10
pcs resource cleanup neutron-server-clone ;
sleep 10
pcs resource cleanup openstack-nova-api-clone ;
sleep 10
pcs resource cleanup openstack-nova-consoleauth-clone ;
sleep 10
pcs resource cleanup openstack-heat-engine-clone ;
sleep 10
pcs resource cleanup openstack-cinder-api-clone ;
sleep 10
pcs resource cleanup openstack-glance-registry-clone ;
sleep 10
pcs resource cleanup httpd-clone ;
# . ./start.sh
In worse case scenario I have to issue start.sh twice from different Controllers
pcs resource cleanup openstack-nova-api-clone attempts to start corresponding
service , which is down at the moment. In fact two cleanups above start all
Nova Services && one neutron cleanup starts all neutron agents as well.
I was also kept track of Galera DB via `clustercheck`
Thanks.
Boris
I guess we're hitting a version problem here: if you deploy the actual
master (i.e. with quickstart) you'll get the environment with the
constraints limited to the core services because of [1] and [2] (so none
of the mentioned services exists in the cluster configuration).
Hope this helps,
