In ocata we changed the ha policy to "ha-exactly" via the following changes:
- tht: Iace6daf27a76cb8ef1050ada0de7ff1f530916c6
- puppet-tripleo: Ib62001c03e1e08f58cf0c6e0ba07a8879a584084
We initially also took care of changing this policy (which is set in the
pacemaker resource agent) for the M/N upgrade path:
I2468a096b5d7042bc801a742a7a85fb1521c1c02
In the end we decided against changing the policy in Newton as well (it
was only for ocata) as it was too close to the release date and we took
the safer path.
This patch does two things:
1) It renames the upgrade function to "newton_ocata" since that is the
only upgrade path we need to take care of
2) It reinstates the actual upgrade function which was mistakenly
removed via an unrelated change in the ceilometer upgrade path:

Currently when we call the major-upgrade step we do the following:
"""
...
if [[ -n $(is_bootstrap_node) ]]; then
check_clean_cluster
fi
...
if [[ -n $(is_bootstrap_node) ]]; then
migrate_full_to_ng_ha
fi
...
for service in $(services_to_migrate); do
manage_systemd_service stop "${service%%-clone}"
...
done
"""
The problem with the above code is that it is open to the following race
condition:
1. Code gets run first on a non-bootstrap controller node so we start
stopping a bunch of services
2. Pacemaker notices will notice that services are down and will mark
the service as stopped
3. Code gets run on the bootstrap node (controller-0) and the
check_clean_cluster function will fail and exit
4. Eventually also the script on the non-bootstrap controller node will
timeout and exit because the cluster never shut down (it never actually
started the shutdown because we failed at 3)
Let's make sure we first only call the HA NG migration step as a
separate heat step. Only afterwards we start shutting down the systemd
services on all nodes.
We also need to move the STONITH_STATE variable into a file because it
is being used across two different scripts (1 and 2) and we need to
store that state.

We currently set the stonith property from all controller nodes during
upgrade. This is racy and can actually end up disabling stonith after
the upgrade even if when it was enabled.
Let's set the property only from the bootstrap node.

Before this change we checked the cluster for any failed actions and
we stopped the upgrade process if there were any.
This is likely eccessive as a failed action could have happened in the
past and the cluster is now fully functional.
Better to check if any of the resources are in Stopped state and break
the upgrade process if any of them are.
We also need to restrict this check to the bootstrap node because
otherwise the following might happen:
1) Bootstrap node does the check, it is successful and it starts
the full HA -> HA NG migration which *will* create failed actions
and will start stopping resources
2) If the check now starts on a non-bootstrap node while 1) is ongoing,
it will find either failed actions or stopped resources so it will
fail.

This commit does the following:
1. We now explicitly disable/stop and then remove the resources that are
moving to systemd. We do this because we want to make sure they are all
stopped before doing a yum upgrade, which otherwise would take ages due
to rabbitmq and galera being down. It is best if we do this via pcs
while we do the HA Full -> HA NG migration because it is simpler to make
sure all the services are stopped at that stage. For extra safety we can
still do a check by hand. By doing it via pacemaker we have the
guarantee that all the migrated services are down already when we stop
the cluster (which happens to be a syncronization point between all
controller nodes). That way we can be certain that they are all down on
all nodes before starting the yum upgrade process.
2. We actually need to start the systemd services in
major_upgrade_controller_pacemaker_2.sh and not stop them.
3. We need to use the proper bash variable name
4. Use is_bootstrap_node everywhere to make the code more consistent

Currently we do not disable openstack-cinder-volume during our
major-upgrade-pacemaker step. This leads to the following scenario. In
major_upgrade_controller_pacemaker_2.sh we do:
start_or_enable_service galera
check_resource galera started 600
....
if [[ -n $(is_bootstrap_node) ]]; then
...
cinder-manage db sync
...
What happens here is that since openstack-cinder-volume was never
disabled it will already be started by pacemaker before we call
cinder-manage and this will give us the following errors during the
start:
06:05:21.861 19482 ERROR cinder.cmd.volume DBError:
(pymysql.err.InternalError) (1054, u"Unknown column 'services.cluster_name' in 'field list'")

In bug https://bugs.launchpad.net/tripleo/+bug/1615035 we fixed the
scheduler_host setting which got deprecated in newton. It seems also the
scheduler_driver settings needs tweaking:
systemctl status openstack-nova-scheduler.service:
2016-09-24 20:24:54.337 15278 WARNING stevedore.named [-] Could not load nova.scheduler.filter_scheduler.FilterScheduler
2016-09-24 20:24:54.338 15278 CRITICAL nova [-] RuntimeError: (u'Cannot load scheduler driver from configuration %(conf)s.',
{'conf': 'nova.scheduler.filter_scheduler.FilterScheduler'})
Let's set this to default during the upgrade step. From newton's nova.conf:
The class of the driver used by the scheduler. This should be chosen
from one of the entrypoints under the namespace 'nova.scheduler.driver'
of file 'setup.cfg'. If nothing is specified in this option, the
'filter_scheduler' is used.
This option also supports deprecated full Python path to the class to
be used. For example, "nova.scheduler.filter_scheduler.FilterScheduler".
But note: this support will be dropped in the N Release.

This is the initial work to have a function that migrates a full HA
architecture as deployed in Mitaka to the HA architecture as deployed in
Newton where only a few resources are managed by pacemaker.
The sequence is the following:
1) We remove the desired services from pacemaker's control. The services
at this point are still running normally via the systemd service as
invoked by pacemaker
2) We do a "systemctl stop <service>" on all controllers for all the
services that were removed from pacemaker's control. We do this to make
sure that during the yum upgrade, the %post sections that call
"systemctl try-restart" do not take ages, because at this point during
the upgrade rabbit is down. The only exceptions are "openstack-core"
and "delay" which are dummy pacemaker resources that do not exist on
the system
3) We do a "systemctl start <service>" on all nodes for all the services
mentioned above.
We should probably merge this patch only when newton has branched as it
is very specific to the M/N upgrade.

For N we cannot assume services are managed by pacemaker.
This adds functions to check if a service is systemd or
pcmk managed and start/stops it accordingly. For pcmk,
only stop/disable on bootstrap node for example, whereas
systemd should stop/start on all controllers.
There is also an equivalent change to the check_resource
which has been reworked to allow both pcmk and systemd.

values yes/no/auto, however in the script we checked for '0' instead of
'no', which means the only effective values were yes/auto. This is now

When the overcloud is upgraded we do a yum update of the packages.
This step might introduce a newer galera version. In such a situation
we need to dump the db and restore it. The high-level workflow should
be the following:
1) During the main upgrade step, before shutting down the cluster
we need to dump the db
2) We upgrade the packages
3) We briefly start mysql on a single node while making sure that
/root/.my.cnf is briefly moved out of the way (because it contains
a password) and import the data. After the import we shutdown this
mysql instance
4) We let the cluster start up normally
The above steps will take place in the following scenarios.
Given a locally installed mariadb version X.Y.Z and release R,
we will dump and restore the DB under the following conditions:
A) MySqlMajorUpgrade template parameter is set to 'auto' and
the upgraded package differs in X, Y *or* Z. We basically don't
dump automatically if the release field changes.
B) MySqlMajorUpgrade template parameter is set to 'yes'
When MySqlMajorUpgrade is set to 'no', no dumping will be performed.
Note that this will give a non functional upgrade if a major mariadb
upgrade is taking place.

Since the Liberty release, the number of services managed by pacemaker
on HA Overcloud has increased. This has an impact on
major_upgrade_controller_pacemaker_1.sh, where cluster sync timeout
value tuned for older releases is now becoming too low.
Raise the cluster sync timeout value to a sensible limit to
give pacemaker enough time to stop the cluster during major upgrade.

It is best if we disable stonith if a cluster has it configured and on,
before we call "pcs cluster stop --all", because should a service fail
to stop for whatever reason, pacemaker will fence the node where it
happened. This is something that we unlikely want during an upgrade as
it will make things worse.
Once the cluster is stopped we can reenable stonith (if it was enabled
to start with) in the CIB while the cluster is shut down.

If "pcs cluster stop --all" is executed on a controller that
happens to have a VIP on the internal network, pcs may use the
VIP as the source address for communication with another cluster
node. When pacemaker is stopped this VIP goes away, and pcs never
receives a response from the other node. This causes pcs to hang
indefinitely; eventually the upgrade times out and fails.
Disabling the VIPs before stopping the cluster avoids this
situation.

Old overcloud images don't have python-zaqarclient installed, and new
overclouds' os-collect-config are configured with Zaqar support. This
together means that on upgrade we need to install python-zaqarclient,
otherwise os-collect-config will be restarted during yum update and
crash due to trying to import missing Python module from zaqarclient.
