Subject: lvm2 and docker issue

Hi Steven,

I have run few tests and so far with --ipc=host it looks better, at least I do not see that "stuck" issue when lvcreate is executed.

docker inspect 417f53c7ac84 | grep -i IPC
            "IpcMode": "host",

Now, how do I specify this option when starting kolla containers?

This one I run manually with this command:

docker run --privileged -t -i --ipc=host --net=host --cap-add=ALL -v /dev:/dev -v /run:/run -v /sys/fs/cgroup:/sys/fs/cgroup:ro -v /sys/kernel/config:/configfs -v /lib/modules:/lib/modules -v /var/lib/cinder:/var/lib/cinder -v /etc/iscsi:/etc/iscsi f4118e59a77a

Thank you

Serguei
You have to extend the kolla_docker module.  An example is here:
https://github.com/openstack/kolla/blob/master/ansible/library/kolla_docker.py#L597

Search the file for the word host - you will probably need stuff wherever that is except with pid duplicated with ipc.  I recommend a patch prior to your current patch to introduce the feature to kolla_docker.

Regards
-steve
