[Openstack] [OpenStack][Mistral]A simple tool to discover and manage custom actions

[int32bit]

Hi, All,

As we know, Mistral allow developer  write a new custom action, but must
reinstall Mistral service if it was installed in our system[1]. I think
it's hardly acceptable for production environment.

So I write a CLI tool used for automatically discovering & registering
custom actions and no need modify any configuration and reinstall any
service. In fact, it's completely independent with Mistral project.

In addition, this project provide a CLI to manage custom actions, we can
list all registered actions, and unregister any action if it doesn't need
any more.

For more detail, please see mistral-actions
.

It work well on our environment but not sure if there is any potential
risk. Thanks for any suggest and comment.

[Openstack] Neutron unable to create VLAN network

[Timothy Geier]

I’m doing some testing/PoC on an RDO Ocata CentOS7 setup and everything has 
gone well with the exception of configuring multiple VLANs.

After following the configuration detailed at 
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html/networking_guide/sec-connect-instance#Using-VLAN-Provider-Networks
 , neutron errors out with the following:

$ neutron net-create 1_network \
--provider:network_type vlan \
--router:external true \
--provider:physical_network extnet \
--provider:segmentation_id 1 --shared
Unable to create the network. The VLAN 1 on physical network extnet is in use.

extnet is mapped to the OVSbridge br-ex, which has a physical interface that’s 
trunked to all of the available VLANs..trying this command on the other 
available VLANs works, but 1 and 2 (the ones I want to test on) always fails.  
Is there anything obvious to try on the system itself or is this more likely a 
network issue?

Thanks much,

That means vlan 1 is in use by one of the other networks.

Re: [Openstack] Strange: lost physical connectivity to compute hosts when using native (ryu) openflow interface

[Gustavo Randich]

Hi Kevin, here is some information aout this issue:

- if the network outage lasts less than ~1 minute, then connectivity to
host and instances is automatically restored without problem

- otherwise:

- upon outage, "ovs-vsctl show" reports "is_connected: true" in all bridges
(br-ex / br-int / br-tun)

- after about ~1 minute, "ovs-vsctl show" ceases to show "is_connected:
true" on every bridge

- upon restoring physical interface (fix outage)

- "ovs-vsctl show" now reports "is_connected: true" in all bridges
(br-ex / br-int / br-tun)

   - access to host and VMs is NOT restored, although some pings are
sporadically answered by host (~1 out of 20)


- to restore connectivity, we:


  - execute "ifdown br-ex; ifup br-ex" -> access to host is restored,
but not to VMs


  - restart neutron-openvswitch-agent -> access to VMs is restored

Thank you!

Re: [Openstack] Neutron unable to create VLAN network

[Kaustubh Kelkar]

VLAN 1 might be treated as the “default” VLAN by your switch.

[Openstack] 答复: 答复: [openstack-dev] 答复: OpenStack-Ansible HA solution

[Liyuenan (Maxwell Li)]

Hi Sampath

If OSA want to add a role to configure Masakari, maybe I can controbute or 
review some code. I had wrote some ansible yaml yet.

Thank you for your help!

Hi Maxwell,

 > It is so kind of you if you can touch Masakari team.
No problem. I will bring up this topic in Masakari team meetup in Boston summit.
If you are attend to summit, it would be great if you could attend to the 
discussion.
Please check [1] for Masakri meetings at summit. ( it will update)

 I found that OSA use keepalived to resolve controller HA, but 
 whether the keepalived support compute HA? What shoud I do or which 
 file I need to config if I want to resolve compute HA?



 And there are some solutions for compute HA in this web:
 http://aspiers.github.io/openstack-summit-2016-austin-compute-ha/ .
 Would the OSA use pacemaker or some other solutions to support compute HA?

[Openstack] Deployment for production

[Satish Patel]

We did POC on RDO and we are happy with product but now question is, should we 
use RDO for production deployment or other open source flavor available to 
deploy on prod. Not sure what is the best method of production deployment?
