Description
===========
all periodic tasks of nova-compute don't work
report_state works.
Steps to reproduce
==================
after some error of our virtulization product happened.
At that time, get_available_nodes of the driver can not fulfil and throw a exception that does nto inherit from Excetipn
Expected result
===============
all periodic task should keep going
Actual result
=============
all periodic tasks stop
Analysis
=============
I found that the coroutine has disappear and run_periodic_tasks in periodic_task.py does not catch BaseException
Solution
=============
run_periodic_tasks should catch all exception.
This is a major problem. All periodic_task died even those tasks which work well and don't throw exception.
Because they belong to a same coroutine.
We should keep nova-compute robust.
Environment
===========
1. Exact version of OpenStack you are running. See the following
list for all releases: http://docs.openstack.org/releases/
openstack-nova-common-16.0.1-1.el7.noarch
python2-novaclient-9.1.0-1.noarch
python-nova-16.0.1-1.el7.noarch
openstack-nova-compute-16.0.1-1.noarch
2. Which hypervisor did you use?
Our own virtulization product
2. Which storage type did you use?
None
3. Which networking type did you use?
Neutron with our sdn |
