[Rdo-list] Manual creation of stripped lvm volume in cinder.
by Rafał Radecki
Hi All.
I am using RDO Juno on CentOS 7 and currently am trying to change an
existing volume attached to an openstack instance. The cinder node is a
separate one from the compute node with mentioned instance. On cinder node
I am using LVM backend with ISCSI. I noticed that when I create a volume in
cinder it is created as a linear one in LVM and I would like to change it
to a stripped one to take advantage of multiple physical disks available.
Is there a way to manually create a LVM volume, notify iscsi daemon on
cinder node to export it and the mount it on the target instance? Any howto
about that? ;)
Or maybe is there a way to tell cinder to create stripped logical volumes
in LVM backend by default (instead of linear ones)?
BR,
Rafal.

Does cloud-native have to mean all-in? by Gordon Haff
Cloud-native application architectures promise improved business agility
and the ability to innovate more rapidly than ever before. However, many
existing conventional applications will provide important business value
for many years. Does an organization have to commit 100% to one
architecture versus another to realize true business benefits?

Right, what Lars means is that eth1 is physically connected to a
network with the 10.1.0.0/24 subnet, and eth2 is physically connected
to a network with the 10.2.0.0/24 subnet.
You might notice that in Lars's instructions, he never puts a host IP
on either interface.

Let me refer you to this page, which explains the basics of creating
and managing Neutron networks:
http://docs.openstack.org/user-guide/cli_create_and_manage_networks.html
You will have to create an external network, which you will associate
with a physical network via a bridge mapping. The default bridge
mapping for br-ex is datacentre:br-ex.
Using the name of the physical network "datacentre", we can create an
external network:
[If the external network is on VLAN 104]
neutron net-create ext-net --router:external \
--provider:physical_network datacentre \
--provider:network_type vlan \
--provider:segmentation_id 104
[If the external net is on the native VLAN (flat)]
neutron net-create ext-net --router:external \
--provider:physical_network datacentre \
--provider:network_type flat
Next, you must create a subnet for the network, including the range of
floating IPs (allocation pool):
neutron subnet-create --name ext-subnet \
--enable_dhcp=False \
--allocation-pool start=10.10.10.50,end=10.10.10.100 \
--gateway 10.10.10.1 \
ext-net 10.10.10.0/24
Next, you have to create a router:
neutron router-create ext-router
You then add an interface to the router. Since Neutron will assign the
first address in the subnet to the router by default (10.10.10.1), you
will want to first create a port with a specific IP, then assign that
port to the router.
neutron port-create ext-net --fixed-ip ip_address=10.10.10.254
You will need to note the UUID of the newly created port. You can also
see this with "neutron port-list". Now, create the router interface
with the port you just created:
neutron router-interface-add ext-router port=<UUID>
>> If you want to be able to ping 10.10.10.x from the host, then you

I think you will have better luck once you create the external network
and router. You can then use namespaces to ping the network from the
router:
First, obtain the qrouter-<UUID> from the list of namespaces:
sudo ip netns list
Then, find the qrouter-<UUID> and ping from there:
ip netns exec qrouter-XXXX-XXXX-XXX-XXX ping 10.10.10.1

[Rdo-list] Skipping resources while running stack update
by Qasim Sarfraz
Folks,
I have an overcloud stack with three controller and three computes. I want
to scale out the cluster by adding new compute nodes.
But I don't want to update the resources on already installed overcloud
nodes. Is there a way to do this?

[Rdo-list] Max VM filesystem size?
by Erich Weiler
Hi Y'all,
I have a bunch of OpenStack Nova nodes, each with 11TB of local disk for
Cloud VMs. This is all on RDO - RHEL 7 on OpenStack Kilo. That local
storage is configured with a XFS filesystem.
If I specify 8TB on 'root filesystem size' in a flavor, it only seems to
be able to make a 2TB root filesystem on the guest. No matter what
guest OS I use (I've tried CentOS 7.1, Ubuntu 15.10, others) it only
seems to be able to create a 2TB root filesystem. I've also tried
making a 5GB root filesystem and specifying 8TB for ephemeral disk, but
the ephemeral disk that shows up on /tmp in the guest is only 2TB as well.
Is there a 2TB KVM limit on VM size? Max file size in ext4 and XFS is
well beyond 2TB, so I don't think that's it... Maybe a limit in KVM or
libvirt?
The qemu xml file on the node does specify a 8TB disk....
Any insight most welcome!!
cheers,
erich

[Rdo-list] Quick rabbitmq question....
by Erich Weiler
Hi Y'all,
I'm sure someone has encountered this issue... basically my rabbitmq
instance on my controller node is running out of file descriptors, this
is on RHEL 7. I've upped the max file descriptors (nofile) to 1000000
in /etc/security/limits.conf, and my sysctl limit for file descriptors
is equally huge. Yet, I can't get my rabbitmq process to get it's
limit's past 1000 or so:

This is causing huge problems in my OpenStack cluster (Kilo Release).
I've read that you can set this limit in /etc/rabbitmq/rabbitmq-env.conf
or /etc/rabbitmq/rabbitmq.config but no matter what I do there I get
nothing, after restarting rabbitmq many times. Does this have something
to do with systemd?

Anyone know how to get the file descriptor limits up for rabbitmq? I've
only got like 40 nodes in my OpenStack cluster, and it's choking, and I
need to add several hundred more nodes...
Any help much appreciated!!! I looked around the list and couldn't find
anything on this, and I've RTFM'd as much as I could...
cheers,
