Re: [Openstack] LinuxBridge Agent Error

Mon, 10 Apr 2017 13:21:07 -0700

Installing the "conntrack-tools" package from the "centos-openstack-ocata" repository seems to have fixed the problem.
My question is if this should have happened automatically during installation and if yes why it didn't happen? 

Best,

G.

Hello,

I am on CentOS 7 and this is a manual Ocata installation as described
on the deployment guide.

My cloud seems to be operating normally even with these messages. The
thing is that I don't like all these (there are a whole bunch of them
every second) in my log files.

I will try to see if I am missing the "conntrack" and try to install
the patch that will provide more info..


Best,

G.


Is this a packstack installation?

You may be missing whatever package in your distro provides the
