Open Stack

hello
i use masakari for migrate servers when the compute being down.
i install these container on the region:
masakari-monitors
masakari-engine
masakari-api
hacluster-pacemaker
hacluster-corosync
and on the compute server i install "hacluster-pacemaker-remote".
In openstack i created segment and I added 2 hosts (in this case the name
of that 2 hosts are: R3SG5 & R3SG12).
for testing evacuate function i shut off one of that compute that i added
in host.
(in this case i shutoff R3SG5)
i attached the log that i found in this directory:
/var/log/kolla/masakari/masakari-hostmonitor.log

also i checked nova_scheduler logs and on that directory i receive error:

***
ERROR oslo_messaging.rpc.server nova.exception.NoValidHost: No valid host
was found. There are not enough hosts available.
*******

finally in OpenStack dashboard in the notification section tatus change
from running to failed.  after the error state that shows in the
notification section, my VM that was on R3SG5 became to ERROR state and the
VM still exists on  R3SG5 and it doenst been migrated to R3SG12.

could you please help me why evacuate function doesn't work correctly?
