<div class="">I saw something similar did you restart
all the services after the upgrade? Just wonder. I saw
some other issue when I upgraded from 7.3 to 7.4 where
it gave me some vif error after all servers reboot the

<div class=""><br class="">
</div>
<div class="">A few days ago, we made two big
changes on our production infrastructure: we
updated to latest Ocata and we changed the
outgoing port on our network node to a lacp
port. We made the change by switching the
port in br-ex in openvswitch to the new
lacp-backed port. Ever since these two
things happened right after the other, we’ve
ran into two issues, one which has much
worse consequences than the other:</div>
<div class=""><br class="">
</div>
<div class="">1.We can’t add floating ips to
instances anymore. The interface says the
operation completed successfully, the
database gets updated, but the IP address
doesn’t exist in the network namespace on
the network nodes. Strangely enough, the
iptables rules in the NAT table do exist.
The port just doesn’t receive the new
address. Adding the floating ip address
manually to the virtual interface with "ip
netns exec *qrouter namespace id* ip addr
add *ip address* dev *virtual interface*"
solves this, but is in no way a permanent
solution.</div>
<div class=""><br class="">
</div>
<div class="">2.We’re getting an error message
in the L3-agent whenever it starts informing
us it was unable to add some rules in
iptables because there’s a lock on xtables,
while as far as we know, the L3-agent itself
is the one holding the lock. Here’s the
error: </div>
