Hi Boris,
so, for what I see the pcs commands that stops and starts the cluster on
the rebooted node should not be used. It can happen that a service fails
to start but we need to investigate why from the logs.

Remember that cleaning up resources can be useful if we know what
happened, but using it repeatedly makes no sense. In addition remember
that you can use just "pcs resource cleanup" to cleanup the entire
cluster status and in some way "start from the beginning".

Now, about this specific problem we need to understand what is happening
here. Correct me if I'm wrong:

1) We have a clean env in which we reboot a node;
    That is correct

2) The nodes comes up, but some resources fails;
    All resources fail

3) After some cleanups the env becomes clean again;

    a)   If VENV is setup by instack-virt-setup ( official guide )
          Mentioned script start.sh works right a way . It comes as well from official guide.

     b) if VENV is setup by Tripleo QuickStart ( where undecloud.qcow2 gets uploaded
          to libvirt pool already having overcloud images integrated per Jon's Video explanation
          QuickStart CI  vs Tripleo CI  )
          then ( via my experience )   before attempting start.sh I MUST  restart PCS Cluster
          on bounced Controller-X , then invoke `. ./start.sh`  ( not simply ./start.sh )
              Pretty often second run start.sh is required from another controller-Y.
          Some times I cannot fix it in script mode and have manually run commands giving
          delay more the 10 sec.  So finally ( about 25 tests passed) I get `pcs status` OK.
          In other words all service are up and running on every controller-X,Y,Z

systematic and can we reproduce it?

Mitaka stable  :-

[tripleo-quickstart@stack] $ bash quickstart --config ./ha.yml $VIRTHOST
By default , no --release specified Mitaka Delorean trunks get selected
Just check /etc/yum.repos.d/ for delorean.repos
quickstart places on   undercloud  when it exits asking to to connect to undercloud
