[ironic] [stable] Bifrost stable/stein is broken (by eventlet?): help needed
by Dmitry Tantsur 07 Sep '20

07 Sep '20

Hi folks, I'm trying to revive the Bifrost stable/stein CI, and after fixing a bunch of issues in https://review.opendev.org/749014 I've hit a wall with what seems an eventlet problem: ironic-inspector fails to start with: Exception AttributeError: "'_SocketDuckForFd' object has no attribute '_closed'" in <bound method _SocketDuckForFd.__del__ of _SocketDuckForFd:16> ignored I've managed to find similar issues, but they should have been resolved in the eventlet version in stein (0.24.1). Any ideas? If we cannot fix it, we'll have to EOL stein and earlier on bifrost.

watchdog fed successfully event of 6300esb
by ligang (P) 07 Sep '20

07 Sep '20

Hi folks, I have an question to discuss about the 6300esb watchdog. I think is it possible that qemu can send an event while the watchdog successfully fed by the vm at the first time. Here is the situation: Qemu will send an VIR_DOMAIN_EVENT_ID_WATCHDOG event while watch dog timeout, and if the action of the watchdog in xml of the vm was set to "reset", the vm will be rebooted while timeout. I have an monitor process that register callback function of the VIR_DOMAIN_EVENT_ID_WATCHDOG event, the callback function will send an alarm to my upper layer monitor platform indicate that the vm is fault, and the cluster deployed business on the vm will isolate the vm by the alarm. And after the vm rebooted , the monitor process will receive an reboot event and send it to the platform, the upper layer monitor platform will clear the alarm, and business continue to run on the vm. In most cases ,the watch dog process in vm will feed the watchdog after vm rebooted and all things go back on track. In some other cases,the guestos may failed to start (in my environment vm start failed by io error), but the reboot event will still be received and the alarm will be cleared and the vm is still fault. So the this may not a good idea to clear the alarm by the reboot event. So, I think it will be helpful that the qemu can send an event while the watchdog successfully fed by the vm at the first time. So I can exactly know that the guest os go back on running and the watch dog initialized successfully. Or any other opintion about this situation. Thanks.

by Mark Goddard 07 Sep '20

07 Sep '20

Hi, The next PTG will be virtual again, and held from Monday October 26th to Friday October 30th. For those who have not attended before, the PTG is where we discuss various aspects of the project, and eventually decide on priorities for the next development cycle. I have provisionally booked the same slots as last time: * Monday 26th 13:00 - 17:00 UTC (kolla & kolla ansible) * Tuesday 27th 13:00 - 17:00 UTC (kolla & kolla ansible) * Wednesday 28th 13:00 - 15:00 UTC (kayobe) Please get in touch if you would like to attend but these slots are not suitable for you. In particular, if you are in a time zone where these times are unsociable, we could consider running some sessions during a different 4 hour block. Thanks, Mark

[kolla-ansible] Difference between deploy and reconfigure?
by Tony Liu 06 Sep '20

06 Sep '20

Hi, What's the difference between deploy and reconfigure? I checked some roles, reconfigure.yml just include_tasks deploy.yml. And I didn't find reconfigure as a condition for any tasks or handlers. I checked kolla-ansible script, the difference is ANSIBLE_SERIAL is specified by reconfigure. I also see comment saying "Serial is not recommended and disabled by default.". Here are some cases. I'd like to know which should be used. #1 Add compute. After updating inventory with the new compute node, "deploy --limit new-compute" and "reconfigure --limit new-compute", do they have the same result? If not, what's the difference? #2 Change configuration. In case configuration is changed in global.yml or inventory, which of "deploy" or "reconfigure" should be executed to update the cluster? Same or any difference? #3 Fix the cluster I was told to rerun playbook to fix some problems, like a container was deleted. "deploy --limit host" or "reconfigure --limit host"? Same or any difference? Thanks! Tony

[Kolla Ansible] Error in "heat" stage during deployment - Followed Quick Start Guide (ubuntu 18.04.5, virtualbox)
by Lukasluedke＠web.de 05 Sep '20

05 Sep '20

Hi everyone, I am new to openstack and just followed the "Quick Start" guide for kolla-ansible [https://docs.openstack.org/kolla-ansible/ussuri/user/quickstart.html] on ussuri release, but now having some problems during deployment. I used virtualbox to create a new vm with ubuntu 18.04.5 [https://releases.ubuntu.com/18.04/ubuntu-18.04.5-live-server-amd64.iso.torr…] and attached one interface (enp0s3, 10.0.2.15) with Nat-Network and the second interface as for the neutron interface (enp0s8, no ip) an internal network and named it "neutron". Then I followed the guide to create a new virtual python environment (logged in over ssh using "user" user). -- sudo apt-get update sudo apt-get install python3-dev libffi-dev gcc libssl-dev sudo apt-get install python3-venv python3 -m venv $(pwd) source $(pwd)/bin/activate pip install -U pip pip install 'ansible<2.10' -- Everything seems to work as mentioned with no problems so far. (Beside the missing "python-venv" package in the docs) -- pip install kolla-ansible sudo mkdir -p /etc/kolla sudo chown $USER:$USER /etc/kolla cp -r $(pwd)/share/kolla-ansible/etc_examples/kolla/* /etc/kolla cp $(pwd)/share/kolla-ansible/ansible/inventory/* . mkdir /etc/ansible sudo nano /etc/ansible/ansible.cfg ### content from /etc/ansible/ansible.cfg [defaults] host_key_checking=False pipelining=True forks=100 ### -- I then modified the "multinode" file to only deploy on localhost (replaced all control01, etc. with localhost) as I first wanted to try openstack on one node. The ping worked, changed the globals.yml file according to the documentation, then bootstrap and the prechecks worked so far with no issue. -- ansible -i multinode all -m ping kolla-genpwd sudo nano /etc/kolla/globals.yml ### additional content of /etc/kolla/globals.yml kolla_base_distro: "ubuntu" kolla_install_type: "source" network_interface: "enp0s3" neutron_external_interface: "enp0s8" kolla_internal_vip_address: "10.0.2.10" ### kolla-ansible -i ./multinode bootstrap-servers kolla-ansible -i ./multinode prechecks -- But on the deploy stage I am stuck right now: -- kolla-ansible -i ./multinode deploy -- The mentioned error is telling me, that the keystone service is not available. I attached the error log file, because the error is longer. As a side node, now when I try to login using tty, the vm is nearly frozen and only prompts very, very slowly (about 10 minutes for prompt). ssh in putty is also frozen and the connection broke after about 30 minutes. Does anyone know what is wrong or has some hints/insight on how to correctly deploy openstack using kolla-ansible? Best Regards, Lukas Lüdke

[TC] Looking for a volunteer to help with community goal selection
by Nate Johnston 04 Sep '20

04 Sep '20

TC members, Since I have not been able to get in contact with Graham, I would like to see if there is anyone who would like to work with me for the selection of community goals for the W series. The commitment would be to identify a few good candidates that have well formulated goal proposals and champions, which usually involves a meeting followed by some reaching out and logistical work. I am hoping to increase the pool of those familiar with the goal selection process, so this is a great place to jump in if you have not done this before. Also, if Graham does have time then we can make sure to include him as well. Two is good but three is better! Please let me know if you are interested. Thanks! Nate

Mentoring Boston University Students
by Kendall Nelson 04 Sep '20

04 Sep '20

Hello! As you may or may not know, the last two years various community members have mentored students from North Dakota State University for a semester to work on projects in OpenStack. Recently, I learned of a similar program at Boston University and they are still looking for mentors interested for the upcoming semester. Essentially you would have 5 to 7 students for 13 weeks to mentor and work on some feature or effort in your project. The time to apply is running out however as the deadline is Sept 3rd. If you are interested, please let me know ASAP! I am happy to help get the students up to speed with the community and getting their workspaces set up, but the actual work they would do is more up to you :) -Kendall (diablo_rojo)

[all][TC] OpenStack Client (OSC) vs python-*clients
by Belmiro Moreira 04 Sep '20

04 Sep '20

Hi, during the last PTG the TC discussed the problem of supporting different clients (OpenStack Client - OSC vs python-*clients) [1]. Currently, we don't have feature parity between the OSC and the python-*clients. Different OpenStack projects invest in different clients. This can be a huge problem for users/ops. Depending on the projects deployed in their infrastructures, they need to use different clients for different tasks. It's confusing because of the partial implementation in the OSC. There was also the proposal to enforce new functionality only in the SDK (and optionally the OSC) and not the project’s specific clients to stop increasing the disparity between the two. We would like to understand first the problems and missing pieces that projects are facing to move into OSC and help to overcome them. Let us know.

[nova] Session Recording for Feedback
by Apsey, Christopher 04 Sep '20

04 Sep '20

Nova supports using the websockify -record functionality to capture frames sent over arbitrary console sessions. Currently, the record = path/to/file option in nova.conf saves these sessions on nova-(spice|vnc)proxy endpoints at the specified path in the format of /path/to/file.(session number). These session numbers appear to be incrementally created starting from 1 and don't really have an association with their respective instance from what I can tell. It would be useful to have these files saved using the instance UUID instead. Ignoring that minor problem, playing back these files is a challenge. I've tried using noVNCs vnc_playback.html function from both the master branch and stable/v0.6 with no luck - it looks like the libraries and the utilities haven't been maintained at the same cadence and there are missing functions that the player is expecting. My goal here is to be able to capture the activities of students as they progress through various exercises and then have instructors be able to go over their work with them after the fact if they have questions. Has anyone been able to do this (or something like this) successfully, or are we just better off trying to do this in-band per instance? Chris Apsey GEORGIA CYBER CENTER

[oslo] Feature Freeze
by Ben Nemec 03 Sep '20

03 Sep '20

This is just a heads up that Oslo is now in feature freeze. Any changes that would require a feature release of an Oslo library will need to request an FFE if they want to make the Victoria release. Please send an email tagged "[oslo][ffe]" to the list to make such a request. I expect we'll branch the Oslo repos in the near future, so some feature development can continue then. However, we generally prefer not to merge invasive changes between feature freeze and release just in case a last-minute bugfix backport is needed. Disentangling a bug fix from a major feature could be a chore. Thanks. -Ben

Hi All, I was wondering if anyone has come across an issue with libvirt seemingly having an issue with instances all of a sudden "locking up" with the following error: Failed to terminate process 2263874 with SIGKILL: Device or resource busy In the nova logs I am seeing: 2020-09-03 09:13:43.208 2659995 INFO nova.compute.manager [req-7ffb9b7c-799b-40dc-be04-598bfda2e2fc 6ddb647baf9343b09d7f8f7a32b0b43d 8cce5e1532e6435a90b168077664bbdf - default default] [instance: f3a8c916-28f5-432d-9b8e-c3056d2dee5a] Rebooting instance 2020-09-03 09:15:52.429 2659995 WARNING nova.virt.libvirt.driver [req-7ffb9b7c-799b-40dc-be04-598bfda2e2fc 6ddb647baf9343b09d7f8f7a32b0b43d 8cce5e1532e6435a90b168077664bbdf - default default] [instance: f3a8c916-28f5-432d-9b8e-c3056d2dee5a] Failed to soft reboot instance.

It seems to be caused when a reboot happens to an instance. If you reset the state and try again, the same error occurs. You also seemingly cannot kill off any libvirt process that is attached to that instance. To me it looks like it could be a kernel issue with libvirt but I could be wrong? Does anyone know of a workaround for this other than maybe restarting a compute host? Many thanks,

[openstack-ansible] OpenStack Ansible deployment fails due to lxc containers not having network connection

I'm trying to deploy OpenStack Ansible. When running the first playbook ```openstack-ansible setup-hosts.yml```, there are errors for all containers during the task ```[openstack_hosts : Remove the blacklisted packages]``` (see below) and the playbook fails. ``` fatal: [infra1_repo_container-1f1565cd]: FAILED! => {"changed": false, "cmd": "apt-get update", "msg": "E: The repository 'http://ubuntu.mirror.lrz.de/ubuntu bionic Release' no longer has a Release file.

Running ```ip r``` on the infra_cinder container yields: ``` 10.0.3.0/24 dev eth2 proto kernel scope link src 10.0.3.5 192.168.110.0/24 dev eth1 proto kernel scope link src 192.168.110.232 ``` so there seems to be no default route which is why the connection fails (similar for the other infra containers). Shouldn't OSA automatically configure this? I didn't find anything regarding a default route on containers in the Docs.

[API SIG] Ending office hours for the API-SIG
by Michael McCune 03 Sep '20

03 Sep '20

hello all, the API-SIG has held meetings and office hours for several years now. since our migration from a weekly meeting to an office hour we have monitored a continual decrease in attendance for these hours, aside from the core membership. after discussion over the course of the last month or two, we have agreed to end the API-SIG office hours. we will hold office hours this week as our final meeting. if you need to contact the SIG in the future, we are still available in the #openstack-sdks channel on freenode as well as here on the mailing list. in the future we would like to see continued migration of the API-SIG closer to the SDKs group. these two groups will essentially become a singular place to discuss all things related to SDKs and APIs in OpenStack. thank you all for the years of participation and discussion that helped us as a community to define a set of best practices and guidelines for API work in OpenStack. peace o/

senlin auto scaling question
by Satish Patel 03 Sep '20

03 Sep '20

Folks, I have created very simple cluster using following command openstack cluster create --profile myserver --desired-capacity 2 --min-size 2 --max-size 3 --strict my-asg It spun up 2 vm immediately now because the desired capacity is 2 so I am assuming if any node dies in the cluster it should spin up node to make count 2 right? so i killed one of node with "nove delete <instance-foo-1>" but senlin didn't create node automatically to make desired capacity 2 (In AWS when you kill node in ASG it will create new node so is this senlin different then AWS?)

[kolla] questions when using external mysql
by sosogh 03 Sep '20

03 Sep '20

Hi list: I want to use kolla-ansible to deploy openstack , but using external mysql. I am following these docs: https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html https://docs.openstack.org/kolla-ansible/latest/reference/databases/externa…. I have some questions: ################ ## Question 1 ## ################ According to the offical doc , if setting it in inventory file(multinode), kolla-ansible -i ./multinode deploy will throw out error: I guest when kolla-ansible running the playbook against myexternalmariadbloadbalancer.com , the """register: find_custom_fluentd_inputs""" in """TASK [common : Find custom fluentd input config files]""" maybe null . ################ ## Question 2 ## ################ According to the offical doc , If the MariaDB username is not root, set database_username in /etc/kolla/globals.yml file: But in kolla-ansible/ansible/roles/xxxxxx/tasks/bootstrap.yml , they use ''' login_user: "{{ database_user }}" ''' ， for example : So at last , I took the following steps: 1. """not""" setting [mariadb] in inventory file(multinode) 2. set "database_user: openstack" for "privillegeduser" PS: My idea is that if using an external ready-to-use mysql (cluster), it is enough to tell kolla-ansible only the address/user/password of the external DB. i.e. setting them in the file /etc/kolla/globals.yml and passwords.yml , no need to add it into inventory file(multinode) Finally , it is successful to deploy openstack via kolla-ansible . So far I have not found any problems. Are the steps what I took good ( enough ) ? Thank you !

[ovn][neutron][ussuri] How to configure for overlay in DPDK with OVN ?

Hi, I’m trying to implement dpdk-ovs with ovn for our openstack environment. I create a bond interface(tunbound) with ovs and tun0 and tun1 are slave interfaces of the bond interface named tunbond. Bridge br-int fail_mode: secure datapath_type: netdev Port tunbond Interface tun0 type: dpdk options: {dpdk-devargs="0000:1a:00.1", n_rxq="2"} Interface tun1 type: dpdk options: {dpdk-devargs="0000:d8:00.1", n_rxq="2"} Port br-int Interface br-int type: internal Now, I need to configure remote-ovn options to the ovs. *I am confused how can I define the IP address of the bonded interface with ovs?* Theses are commands for connect remote ovn services. ovs-vsctl set open . external-ids:ovn-remote=tcp:{controller ip}:6642 ovs-vsctl set open . external-ids:ovn-encap-type=geneve *1* This below command make it me confused. ovs-vsctl set open . external-ids:ovn-encap-ip={local ip} How should I resolve this issue?

[tripleo, ironic] Error: Could not retrieve ... pxelinux.0
by Pete Zaitcev 02 Sep '20

Hello: I wanted to give the TripleO a try, so started follow our installation guide for Ussuri, and eventually made it to "openstack undercloud install". It fails with something like this: Aug 28 10:10:53 undercloud puppet-user[48657]: Error: /Stage[main]/Ironic::Pxe/File[/var/lib/ironic/tftpboot/ipxe.efi]: Could not evaluate: Could not retrieve information from environment production source(s) file:/usr/share/ipxe/ipxe-x86_64.efi Aug 27 20:05:42 undercloud puppet-user[37048]: Error: /Stage[main]/Ironic::Pxe/Ironic::Pxe::Tftpboot_file[pxelinux.0]/File[/var/lib/ironic/tftpboot/pxelinux.0]: Could not evaluate: Could not retrieve information from environment production source(s) file:/tftpboot/pxelinux.0 Does anyone have an idea what it wants? I added a couple of packages on the host system that provided the files mentioned in the message, but it made no difference. Ussuri is conteinerized anyway. Since I'm very new to this, I have no clue where to look at all. The nearest task is a wrapper of some kind, so the install-undercloud.log looks like this: 2020-08-28 14:11:31.397 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] TASK [Run container-puppet tasks (generate config) during step 1 with paunch] *** 2020-08-28 14:11:31.397 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] Friday 28 August 2020 14:11:31 -0400 (0:00:00.302) 0:06:28.734 ********* 2020-08-28 14:11:32.223 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] changed: [undercloud] 2020-08-28 14:11:32.325 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] 2020-08-28 14:11:32.326 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] TASK [Wait for container-puppet tasks (generate config) to finish] ************* 2020-08-28 14:11:32.326 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] Friday 28 August 2020 14:11:32 -0400 (0:00:00.928) 0:06:29.663 ********* 2020-08-28 14:11:32.948 60599 WARNING tripleoclient.v1.tripleo_deploy.Deploy [ ] WAITING FOR COMPLETION: Wait for container-puppet tasks (generate config) to finish (1200 retries left). . . .

Re: [neutron][ovn] OVN Performance
by Apsey, Christopher 02 Sep '20

02 Sep '20

All, Just wanted to loop back here and give an update. For reference, [1] (blue means successful action, red means failed action) is the result we got when booting 5000 instances in rally [2] before the Red Hat OVN devs poked around inside our environment, and [3] is the result after. The differences are obviously pretty significant. I think the biggest change was setting metadata_workers = 2 in neutron_ovn_metadata_agent.ini on the compute nodes per https://bugs.launchpad.net/neutron/+bug/1893656. We have 64C/128T on all compute nodes, so the default neutron calculation of scaling metadata workers based on available cores created 900+ connections to the southbound db at idle; after the control plane got loaded up it just quit around 2500 instances (my guess is it hit the open file limit, although I don’t think increasing it would have made it better for much longer since the number of connections were increasing exponentially). Capping the number of metadata workers decreased open southbound connections by 90%. Even more telling was that rally was able to successfully clean up after itself after we made that change, whereas previously it wasn’t even able to successfully tear down any of the instances that were made, indicating that the control plane was completely toast. Note that the choppiness towards the end of [3] had nothing to do with OVN – our compute nodes had a loadavg approaching 1000 at that point, so they were just starved for cpu cycles. This would have scaled even better with additional compute nodes. The other piece was RAFT. Currently, RDO is shipping with ovs 2.12, but 2.13 has a bunch of RAFT fixes in it that improve stability and knock out some bugs. We were having issues with chassis registration on 2.12, but after using the 2.13 package from cbs, all those issues went away. Big thanks to the great people at Red Hat on the cc line for volunteering their valuable time to take a look. I’m now significantly more comfortable with defaulting to OVN as the backend of choice as the performance delta is now gone. That said, should the community consider dropping linuxbridge as the backend in the official upstream docs and jump straight to OVN rather than ml2/OVS? I think that would increase the test base and help shine light on other issues as time goes on. My org can devote some time to doing this work if the community agrees that it’s the right action to take. Hope that’s helpful!

Coincidentally, Red Hat scale engineers just published an article [1] about work they've done to scale RH-OSP 16.1 (== OpenStack Train on CentOS 8, with OVN 2.13 and TripleO) to 700 compute nodes.

Graceful stopping of RabbitMQ AMQP notification listener
by Anil Jangam 02 Sep '20

02 Sep '20

Hi, I have coded OpenStack AMQP listener following the example and it is working fine. https://github.com/gibizer/nova-notification-demo/blob/master/ws_forwarder.… The related code snippets of the NotificationHandler class are shown as follows. # Initialize the AMQP listener def init(self, cluster_ip, user, password, port): cfg.CONF() cluster_url = "rabbit://" + user + ":" + password + "@" + cluster_ip + ":" + port + "/" transport = oslo_messaging.get_notification_transport(cfg.CONF, url=cluster_url) targets = [ oslo_messaging.Target(topic='versioned_notifications'), ] endpoints = [self.__endpoint] # Initialize the notification listener try: self.__amqp_listener = oslo_messaging.get_notification_listener(transport, targets, endpoints, executor='threading') except NotImplementedError as err: LOGGER.error("Failed to initialize the notification listener {}".format(err)) return False LOGGER.debug("Initialized the notification listener {}".format(cluster_url)) return True # Arm the compute event listeners def start_amqp_event_listener(self): # Start the notification handler LOGGER.debug("Started the OpenStack notification handler") self.__amqp_listener.start() # Disarm the compute event listeners def stop_amqp_event_listener(self): LOGGER.debug("Stopping the OpenStack notification handler") if self.__amqp_listener is not None: self.__amqp_listener.stop() I am using this interface from a new process handler function, however, when I invoke the stop_amqp_eent_listener() method, my process hangs. It does not terminate naturally. I verified that the self.__amqp_listener.stop() function is not returning. Is there anything missing in this code? Is there any specific consideration when calling the listener from a new process? Can someone provide a clue? # Stop the worker def stop(self): # Stop the AMQP notification handler self.__amqp_handler.stop_amqp_event_listener() LOGGER.debug("Stopped the worker for {}".format(self.__ops_conn_info.cluster_ip)) /anil.

[Magnum][Kayobe] Magnum Kubernetes clusters failing to be created (bugs?)
by Tony Pearce 02 Sep '20

02 Sep '20

Hi guys, I hope you are all keeping safe and well at the moment. I am trying to launch Kubernetes clusters into Openstack Train which has been deployed via Kayobe (Kayobe as I understand is a wrapper for kolla-ansible). There have been a few strange issues here and I've struggled to isolate them. These issues started recently after a fresh Openstack deployment some months ago (around February 2020) to give some context. This Openstack is not "live" as I've been trying to get to the bottom of the issues: Issue 1. When trying to launch a cluster we get error "Resource Create Failed: Forbidden: Resources.Kube Masters.Resources[0].Resources.Kube-Master: Only Volume-Backed Servers Are Allowed For Flavors With Zero Disk. " Issue 2. After successfully creating a cluster of a smaller node size, the "resize cluster" is failing (however update the cluster is working). Some background on this specific environment: Deployed via Kayobe, with these components: Cinder, Designate, iscsid, Magnum, Multipathd, neutron provider networks The Cinder component integrates with iSCSI SAN storage using the Nimble driver. This is the only storage. In order to prevent Openstack from allocating Compute node local HDD as instance storage, I have all flavours configured with root disk / ephemeral disk / swap disk = "0MB". This then results in all instance data being stored on the backend Cinder storage appliance. I was able to get a cluster deployed by first creating the template as needed, then when launching the cluster Horizon prompts you for items already there in the template such as number of nodes, node flavour and labels etc. I re-supplied all of the info (as to duplicate it) and then tried creating the cluster. After many many times trying over the course of a few weeks to a few months it was successful. I was then able to work around the issue #2 above to get it increased in size. When looking at the logs for issue #2, it looks like some content is missing in the API but I am not certain. I will include a link to the pastebin below [1]. When trying to resize the cluster, Horizon gives error: "Error: Unable to resize given cluster id: 99693dbf-160a-40e0-9ed4-93f3370367ee". I then searched the controller node /var/log directory for this ID and found "horizon.log [:error] [pid 25] Not Found: /api/container_infra/clusters/99693dbf-160a-40e0-9ed4-93f3370367ee/resize". Going to the Horizon menu "update cluster" allows you to increase the number of nodes and then save/apply the config which does indeed resize the cluster. Regarding issue #1, we've been unable to deploy a cluster in a new project and the error is hinting it relates to the flavours having 0MB disk specified, though this error is new and we've been successful previously with deploying clusters (albeit with the hit-and-miss experiences) using the flavour with 0MB disk as described above. Again I searched for the (stack) ID after the failure, in the logs on the controller and I obtained not much more than the error already seen with Horizon [2]. I was able to create new flavours with root disk = 15GB and then successfully deploy a cluster on the next immediate try. Update cluster from 3 nodes to 6 nodes was also immediately successful. However I see the compute nodes "used" disk space increasing after increasing the cluster size which is an issue as the compute node has very limited HDD capacity (32GB SD card). At this point I also checked 1) previously installed cluster using the 0MB disk flavour and 2) new instances using the 0MB disk flavour. I notice that the previous cluster is having host storage allocated but while the new instance is not having host storage allocated. So the cluster create success is using flavour with disk = 0MB while the result is compute HDD storage being consumed. So with the above, please may I clarify on the following? 1. It seems that 0MB disk flavours may not be supported with magnum now? Could the experts confirm? :) Is there another way that I should be configuring this so that compute node disk is not being consumed (because it is slow and has limited capacity). 2. The issue #1 looks like a bug to me, is it known? If not, is this mail enough to get it realised? Pastebin links as mentioned [1] http://paste.openstack.org/show/797316/ [2] http://paste.openstack.org/show/797318/ Many thanks, Regards, Tony Pearce

[nova] providing a local disk to a Nova instance
by Thomas Goirand 01 Sep '20

01 Sep '20

Hi Nova team! tl;dr: we would like to contribute giving instances access to physical block devices directly on the compute hosts. Would this be accepted? Longer version: About 3 or 4 years ago, someone wrote a spec, so we'd be able to provide a local disk of a compute, directly to a VM to use. This was then rejected, because at the time, Cinder had the blockdevice drive, which was more or less achieving the same thing. Unfortunately, because nobody was maintaining the blockdevice driver in Cinder, and because there was no CI that could test it, the driver got removed. We've investigated how we could otherwise implement it, and one solution would be to use Cinder, but then we'd be going through an iSCSI export, which would drastically reduce performances. Another solution would be to manage KVM instances by hand, not touching anything to libvirt and/or OpenVSwitch, but then we would loose the ease of using the Nova API, so we would prefer to avoid this direction. So we (ie: employees in my company) need to ask the Nova team: would you consider a spec to do what was rejected before, since there's now no other good enough alternative? Our current goal is to be able to provide a disk directly to a VM, so that we could build Ceph clusters with an hyper-converged model (ie: storage hosted on the compute nodes). In this model, we wouldn't need live-migration of a VM with an attached physical block device (though the feature could be added on a later stage). Before we start investigating how this can be done, I need to know if this has at least some chances to be accepted or not. If there is, then we'll probably start an experimental patch locally, then write a spec to properly start this project. So please let us know. Cheers, Thomas Goirand (zigo)

[ops] Restructuring OSOPS tools
by Sean McGinnis 31 Aug '20

31 Aug '20

Hello everyone, We recently expanded the scope of the Ops Docs SIG to also include any ops tooling. I think it's now time to move on to the next step of actually getting some of the old tooling in place and organized how we want it. We have several semi-abandoned repos from back when there was more work being done on ops tooling. During the great rebranding, those all were moved under the x/ namespace: https://opendev.org/x/?tab=&sort=recentupdate&q=osops Since these are now owned by an official SIG, we can move this content back under the openstack/ namespace. That should help increase visibility somewhat, and make things look a little more official. It will also allow contributors to tooling to get recognition for contributing to an import part of the OpenStack ecosystem. I do think it's can be a little more difficult to find things spread out over several repos though. For simplicity with finding tooling, as well as watching for reviews and helping with overall maintenance, I would like to move all of these under a common openstack/osops. Under that repo, we can then have a folder structure with tools/logging, tools/monitoring, etc. Then with everything in one place, we can have docs published in one place that helps find everything and easily links between tools. We can also capture some metadata about the tools, and use that to reflect their state in those docs. Please let me know if there are any objects to this plan. Otherwise, I will start cleaning things up and getting it staged in a new repo to be imported as an official repo owned by the SIG. Thanks! Sean

[TripleO][Ussuri] image prepare, cannot download containers image prepare recently
by Ruslanas Gžibovskis 31 Aug '20

31 Aug '20

Hi all, I have noticed, that recently my undercloud is not able to download images [0]. I have provided newly generated containers-prepare-parameter.yaml and outputs from container image prepare providing --verbose and later beginning of --debug (in the end) [0] were there any changes? As "openstack tripleo container image prepare default --output-env-file containers-prepare-parameter.yaml --local-push-destination" have prepared a bit different file, compared what was previously: NEW # namespace: docker.io/tripleou VS namespace: docker.io/tripleomaster # OLD [0] - http://paste.openstack.org/show/rBCNAQJBEe9y7CKyi9aG/ -- Ruslanas Gžibovskis +370 6030 7030
