What OS image can I use for Docker Swarm in Magnum?
by Paolo Celati 26 Aug '21

26 Aug '21

Hi, I'm looking to set up Docker Swarm using Openstack Magnum and I noticed the user guide for magnum lists only Fedora Atomic as supported. If I'm not mistaken though Atomic has been discontinued for a while now, so I'm wondering what you use for this use case. Can I use Fedora CoreOS instead, and if so are there any gotchas I should know as a first time Magnum user? Thanks in advance, Paolo

[cinder] high-priority reviews this week
by Brian Rosmaita 26 Aug '21

26 Aug '21

Hello Cinder team, As I mentioned at today's meeting, the cinderclient must be released next week, and this means that any Xena cinder features that we want supported in the Xena cinderclient need to merge into cinder first. We've got two cinder patches that introduce new microversions, and thus impact cinderclient. So please put the following patches at the top of your reviewing list: (1) "Snapshot in-use volumes without force flag" cinder: https://review.opendev.org/c/openstack/cinder/+/789564 cinderclient: (simply requires bump in MAX_VERSION, will be done in the release note patch) (2) "Expose volume & snapshot use_quota field" cinder: https://review.opendev.org/c/openstack/cinder/+/786386 cinderclient: https://review.opendev.org/c/openstack/python-cinderclient/+/787407 (very small patch) A slight complication is that 786386 is stacked on top of some other patches. On the other hand, these are all nicely done and present learning opportunities: - https://review.opendev.org/c/openstack/cinder/+/791240/ -- this is a good one to review if you're interested in how the automated tests to verify the request/response samples in the api-ref work - https://review.opendev.org/c/openstack/cinder/+/786383 -- relatively small patch with great unit test coverage - https://review.opendev.org/c/openstack/cinder/+/786384/ -- this is a good one if you want to get better acquainted with Cinder's use of Oslo Versioned Objects - https://review.opendev.org/c/openstack/cinder/+/786385 -- this is worth looking at to see the online data migration strategy Cinder uses to enable rolling upgrades - https://review.opendev.org/c/openstack/cinder/+/786386 -- this is the patch that introduces a new API microversion; it looks big, but a lot of the files are sample requests/responses for the api-ref Happy reviewing!

[election][TripleO] James Slagle candidacy for TripleO PTL for Yoga
by James Slagle 26 Aug '21

26 Aug '21

I'm submitting my candidacy for TripleO PTL. I look forward to the opportunity to help the community as we tackle some of our upcoming challenges — the transition to CentOS/RHEL 9, increasing complexity around container management, and revisiting our commitments to our adopted tooling. I'd suggest that to assist with these efforts, we focus on our review prioritization and in progress work streams. I would like to see folks representing review priorities during the TripleO meeting and on an etherpad. I'd also like to see less parallel streams of work, with the opportunity for more folks to collaborate on common priorities. If elected as PTL, I would plan to organize the efforts around such an approach. Thank you for the consideration. https://review.opendev.org/c/openstack/election/+/805840 -- -- James Slagle --

[kolla][wallaby] nova_libvirt restarting causes vm shutdown
by Ignazio Cassano 26 Aug '21

26 Aug '21

Hello, I tried to update kolla wallaby because new images has been released. During the update nova_libvirt container restarted and all vm went down. So I verified that every time I restart nova_libvirt container, all vm restarted and nova_compute reports lost connection with libvirt. In openstack installations where docker is not used, the libvirt restart does not cause vm shutdown. I opened a bug: https://bugs.launchpad.net/kolla-ansible/+bug/1941706 Ignazio

by wodel youchi 25 Aug '21

25 Aug '21

Hi, I am trying to deploy openstack with tripleO using VMs and nested-KVM for the compute node. This is for test and learning purposes. I am using the Train version and following some tutorials. I prepared my different template files and started the deployment, but I got these errors : *Failed to provision instance fc40457e-4b3c-4402-ae9d-c528f2c2ad30: Asynchronous exception: Node failed to deploy. Exception: Agent API for node 6d3724fc-6f13-4588-bbe5-56bc4f9a4f87 returned HTTP status code 404 with error: Not found: Extension with id iscsi not found. for node* and *Got HTTP 409: {"errors": [{"status": 409, "title": "Conflict", "detail": "There was a conflict when trying to complete your request.\n\n Unable to allocate inventory: Unable to create allocation for 'CUSTOM_BAREMETAL' on resource provider '6d3724fc-6f13-4588-bbe5-56bc4f9a4f87'.

[ops] [cinder] Cinder driver for Dell EMC PS Series on Train
by Massimo Sgaravatto 25 Aug '21

25 Aug '21

Dear all In our Cloud we have multiple backends for Cinder. One of them is using the Dell EMC PS Series volume driver My understanding (reading https://docs.openstack.org/releasenotes/cinder/ussuri.html) is that the driver doesn't work anymore in >= Ussuri A while ago we migrated to Train (using CentOS7 as operating system) and everything kept working fine. We are now trying to migrate to CentOS8 (still using Train) and the cinder volume service for the equallogic backend doesn't work anymore In the log file I found something like this [*] We already planned to dismiss that backend (but we planned to do that before next Openstack update). Does anyone know if that driver is supposed to work with Train and CentOS8 (and therefore python3) ? Thanks, Massimo [*] 021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps [req-9fee10a8-4ad4-4bb3-a04c-46ef6919bb0f - - - - -] Error running command.: TypeError: must be str, not bytes 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps Traceback (most recent call last): 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps File "/usr/lib/python3.6/site-packages/cinder/volume/drivers/dell_emc/ps.py", line 248, in _run_ssh 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps timeout=self.configuration.ssh_conn_timeout) 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps File "/usr/lib/python3.6/site-packages/cinder/volume/drivers/dell_emc/ps.py", line 72, in __inner 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps res = gt.wait() 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps File "/usr/lib/python3.6/site-packages/eventlet/greenthread.py", line 181, in wait 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps return self._exit_event.wait() 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps File "/usr/lib/python3.6/site-packages/eventlet/event.py", line 125, in wait 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps result = hub.switch() 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps File "/usr/lib/python3.6/site-packages/eventlet/hubs/hub.py", line 298, in switch 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps return self.greenlet.switch() 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps File "/usr/lib/python3.6/site-packages/eventlet/greenthread.py", line 221, in main 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps result = function(*args, **kwargs) 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps File "/usr/lib/python3.6/site-packages/cinder/volume/drivers/dell_emc/ps.py", line 196, in _ssh_execute 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps self._get_output(chan) 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps File "/usr/lib/python3.6/site-packages/cinder/volume/drivers/dell_emc/ps.py", line 175, in _get_output 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps out += ret 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps TypeError: must be str, not bytes 2021-08-25 10:13:06.637 30932 ERROR cinder.volume.drivers.dell_emc.ps
