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.

Seems the conditional has changed and we should pickup the
tripleo::profile::base::swift::storage::enable_swift_storage
hiera data.
After controller nodes are upgraded the swift services were down
even though there was no stand-alone swift node (the current
conditional was failing as that hiera isn't set any more)

OPM package is metadata package with unversioned requirements which
means that update does not update the dependencies. This leaves us
with old puppet modules and old puppet during the puppet run.

gnocchi when configured with swift will require keystone
to be available to authenticate to migrate to v3. At this
step keystone is not available and gnocchi upgrade fails
with auth error. Instead start apache in step 3, start
apache first and then run gnocchi upgrade in a separate
step and let upgrade happen here.

With the following two changes we increased the timeout for redis and
rabbit for both starting and stopping to 200s:
https://review.openstack.org/386618 newton (merged)
https://review.openstack.org/385555 master (merged)
We want to also fix that on minor updates on all our supported
releases upstream and downstream (newton, mitaka, liberty, kilo).
This way we can guarantee that we have a uniform timeout for
sart and stop for rabbit and redis across all our releases.

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.

We have the following function in the upgrade process after we updated
the packages and called the db-sync commands:
services=$(services_to_migrate)
...
for service in $(services); do
manage_systemd_service start "${service%%-clone}"
check_resource_systemd "${service%%-clone}" started 600
done
The above is broken because $services contains a list of services to
start, so $(services) will return gibberish and the for loop will never
execute anything.
One of the symptoms for this is the openstack-nova-compute service not
restarting on the compute nodes during the yum -y upgrade. The reason
for this is that during the service restart, nova-compute waits for
nova-conductor to show up in the rabbitmq queues, which cannot happen
since the service was actually never started.

The default path if the operator does nothing is to keep the
sahara services on mitaka to newton upgrades.
If the operator wishes to remove sahara services then they
need to specify the provided major-upgrade-remove-sahara.yaml
environment file in the stack upgrade commands.
The existing migration to ha arch already removes the constraints
and pcs resource for sahara api/engine so we just need to stop
it from starting again if we want to remove it.
This adds a KeepSaharaServiceOnUpgrade parameter to determine if
Sahara is disabled from starting up after the controllers are
upgraded (defaults true).
Finally it is worth noting that we default the sahara services
as 'on' during converge here in the resource_registry of the
converge environment file; any subsequent stack updates where
the deployment contains sahara services will need to
include the -e /environments/services/sahara.yaml environment
file.

As per [1] we need to lower osd max object name and namespace len when
upgrading from Hammer and the OSD is backed by ext4.
These could also be given via ExtraConfig but on upgrade we only run
puppet apply after this script is executed, so the values won't be
effective unless the daemon is restarted. Yet we do not want puppet
to restart the daemon because we can't bring all OSDs down
unconditionally or guests will die.

Previously the chown command wasn't traversing symlinks, causing
the new ownership to not be set for some needed files.
This change also ensures the crush map tunables are set to the 'default'
profile after the upgrade.
Finally redirects the output of a pidof to /dev/null to avoid spurious
logging.

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.

tripleo-heat-templates/extraconfig/tasks/major_upgrade_controller_pacemaker_2.sh
has the following code:
...
check_resource mongod started 600
if [[ -n $(is_bootstrap_node) ]]; then
...
tstart=$(date +%s)
while ! clustercheck; do
sleep 5
tnow=$(date +%s)

systemctl_swift start
for service in $(services_to_migrate); do
manage_systemd_service start "${service%%-clone}"
check_resource_systemd "${service%%-clone}" started 600
done
"""
The problem with the above code is that it is open to the following race
condition:
1) Bootstrap node is busy checking the galera status via cluster check
2) Non-bootstrap node has already reached: start_or_enable_service
rabbitmq and later lines. These lines will be skipped because
start_or_enable_service is a noop on non-bootstrap nodes and
check_resource rabbitmq only checks that pcs status |grep rabbitmq
returns true.
3) Non-bootstrap node can then reach the manage_systemd_service start
and it will fail with stuff like:
"Job for openstack-nova-scheduler.service failed because the control
process exited with error code. See \"systemctl status
openstack-nova-scheduler.service\" and \"journalctl -xe\" for
details.\n" (because the db tables are not migrated yet)
This happens because 3) was started on non-bootstrap nodes before the
db-sync statements are complete on the bootstrap node. I did not feel
like changing the semantics of check_resource and remove the noop on
non-bootstrap nodes as other parts of the tree might rely on this
behaviour.

Currently we do the following in the migration path:
pcs property set maintenance-mode=true
if ! timeout -k 10 300 crm_resource --wait; then
echo_error "ERROR: cluster remained unstable after setting maintenance-mode for more than 300 seconds, exiting."
exit 1
fi
crm_resource --wait can actually take forever under certain conditions.
The property will be set atomically across the cluster nodes so we should be good
without this.

After a successful upgrade to Newton, I ran the tripleo.sh
--overcloud-pingtest and it failed with the following:
resources.test_flavor: Not all flavors have been migrated to the API database (HTTP 409)
The issue is the fact that some tables have migrated to the
nova_api db and we need to migrate the data as well.
Currently we do:
nova-manage db sync
nova-manage api_db sync
We want to add:
nova-manage db online_data_migrations
After launching this command the overcloud-pingtest works correctly:
tripleo.sh -- Overcloud pingtest SUCCEEDED

This issue was spotted during major upgrade where we had calls like
this:
servers: {get_param: servers, Controller}
These get_param calls are hanging indefinitely and make the whole
upgrade end in a timeout. We need to put brackets around the get_param
function when there are multiple arguments:
http://docs.openstack.org/developer/heat/template_guide/hot_spec.html#get-param
This is already done in most of the tree, and the few places where this
was not happening were parts not under CI. After this change the
following grep returns only one false positive:
grep -ir get_param: |grep -v -- '\[' |grep ','

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:

Currently we in major_upgrade_controller_pacemaker_2.sh we are calling
ceilometer-dbsync before mongod is actually started (only galera is
started at this point). This will make the dbsync hang indefinitely
until the heat stack times out.
Now this approach should be okay, but do note that when we start mongod
via systemctl we are not guaranteed that it will be up on all nodes
before we call ceilometer-dbsync. This *should* be okay because
ceilometer-dbsync keeps retrying and eventually one of the nodes will
be available. A completely clean fix here would be to add another
step in heat to have the guarantee that all mongo servers are up and
running before the dbsync call.

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:

{'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.
