Hi
Has anyone had any experience running a DNS VNF on Openstack. Typically for
these VNFs there is a really huge volume of DNS lookups and this translates to
entries for udp in the conntrack table
Sometimes under load this can lead to
nf_conntrack table being FULL
The default max on most systems
Hi Curtis
Thanks for the help. You were spot on in pointing out the issue
Copy pasted previous nova api haproxy config and forgot to update port
Thanks again

Hi
I made all the changes as documented in
https://docs.openstack.org/ocata/install-guide-ubuntu/nova-controller-install.html
https://docs.openstack.org/ocata/install-guide-ubuntu/nova-compute-install.html
The issue im facing is when nova compute comes up and queries the placement API
it seems
al down how
aggressive they are. One thing I should mention is that if you have a large
number of RPC workers, enabling heartbeats will increase cpu consumption about
1-2% per worker (in our experience). Since its now doing something with
rabbitmq every few seconds. This can also increase load on
ection its using is no
longer valid. Heartbeats by itself solved 90%+ of our issues with rabbitmq and
nodes being disconnected and never reconnecting.

Hi
I am seeing on Kilo if I bring down one contoller node sometimes some computes
report down forever.
I need to restart the compute service on compute node to recover. Looks like
oslo is not reconnecting in nova-compute
Here is the Trace from nova-compute

Hi
In a multi node HA deployment for production does key rotate need a keystone
process reboot or should we just run the fernet rotate on one node and
distribute it without restarting any process
I presume keystone can handle the rotation without a restart?
I also assume this key rotation can
Hi
If we deploy Keystone using memcached as token backend we see that bringing
down 1 of 3 memcache servers results in some tokens getting invalidated. Does
memcached not support replication of tokens
So if we wanted HA w.r.t keystone tokens should we use SQL backend for tokens?

Hi
Have a deployment where keystone sits behind a ha proxy node. Now
authentication requests are made to a vip. Problem is when there is an
authentication failure we cannot track the remote ip that failed login as all
authentication failures show the VIP ip since ha proxy fwds the request to a
Hi
How is the rabbit_ha_queues parameter used in configuration files like
nova.conf, neutron.conf, cinder.conf etc
What happens if on the rabbit node the ha queue is set to mirrored but the ha
queues is set to False on client side

Hi
When we configure the control_exchange parameter in each of the openstack
components it defaults to openstack
Is there a recommendation to have separate exchanges per component or just use
the openstack exchange for rabbit
Is there any impact of using one vs the other
