[nova][gate] test_tagged_attachment failing close to 100% in nova-next
by Artom Lifshitz 03 Feb '22

03 Feb '22

https://bugs.launchpad.net/nova/+bug/1959899 The test times out verifying the tags in the metadata API after attaching a NIC and volume. This is happening almost 100% of the time, but I've seen at least a couple of passing runs as well. We have yet to determine what the exact failure mode is - is the metadata API timing out (unlikely, since every other test passes)? Or are the expected tags just not present (more likely)? I'm trying to figure some things out at [1], but other than that this is very much under investigation with no root cause identified yet. [1] https://review.opendev.org/c/openstack/nova/+/827549

[nova][tempest] nova-next gate blocker
by Artom Lifshitz 03 Feb '22

03 Feb '22

nova-next (and possibly others) is broken because of https://bugs.launchpad.net/tempest/+bug/1959682 The fix is at https://review.opendev.org/c/openstack/tempest/+/827305, with a Nova DNM patch to exercise it at https://review.opendev.org/c/openstack/nova/+/827306 Please hold your rechecks until this is resolved. Cheers!

bypass sphinx conf.py from CLI
by Stone, Ronald 03 Feb '22

03 Feb '22

Hi, The StarlingX docs team is implementing the default sphinxcontrib.spelling spelling extension for use from tox via a virtualenv set up for this purpose. We do not want sphinxcontrib.spelling loaded into other tox jobs that won't use it. This means that it cannot be loaded from the standard conf.py. Instead I am bypassing conf.py and setting parameters from the sphinx-build command in the appropriate tox job: sphinx-build -a -E -C --keep-going -d doc/build/doctrees -D extensions=sphinxcontrib.spelling -D spelling_word_list_filename=spelling_wordlist.txt -D rst_prolog="open('./shared/strings.txt', 'r').read()" -t starlingx -t openstack -b spelling doc/source doc/build/spelling {posargs} This works except that we also need to load some strings into the rst prolog for various purposes, and that is failing without warning or errors. I can open the file from a python console. Sphinx-build escapes the single quotes as: open('"'"'./shared/strings.txt'"'"', '"'"'r'"'"').read()' Any suggestions on the correct parameter format appreciated. Ron

[os-brick][nova][cinder][glance] Question about lock_path
by Radosław Piliszek 03 Feb '22

03 Feb '22

Hello Fellow OpenStackers! I have noticed os-brick started using the file locks (in lock_path) to avoid race conditions. I have a question regarding that lock_path - it seems all the cases I have found use separate lock_paths per service, yet the problematic cases listed in the bug report (and the commit message of [1]) suggest that, in case of co-hosted nova-compute, glance-api, cinder-volume and cinder-backup services (or any combination thereof), the lock_path should be shared. Should the deployment projects adapt to actually fix the race condition issue? [1] https://review.opendev.org/c/openstack/os-brick/+/814139 Kind regards, -yoctozepto

[stein][neutron] Static rules losed
by Gargano Andrea 03 Feb '22

03 Feb '22

Hi all, we faced an inssue in our openstack, we have some private clouds with static rules, if the controller that own namespace with the static rule goes down, namespace moves to other controller but it loses the rule. I can still see the rules inside the router on openstack but it doesn't work until recreated. Have you seen something like this? Thank you in advance. Andrea Gargano

[cinder][drivers] stable branch backports
by Brian Rosmaita 02 Feb '22

02 Feb '22

Hello Argonauts, especially vendor driver maintainers: At last week's midcycle meeting, we began a discussion of running third-party CI on stable branch changes. While that continues *not* to be required (it will be re-visited at the Z PTG), we did agree to the following: When a vendor driver patch backport is proposed, we would like to see a clear statement on the gerrit review that the patch has been tested in an appropriate environment. This shouldn't be a big deal because presumably you've done local testing with your backend to ensure that the code works as expected in a stable branch; we're simply asking that this be documented on the backport. cheers, brian

RE: Openstack VLAN provider Network
by DHilsbos＠performair.com 02 Feb '22

02 Feb '22

Felipe; A lot of this will depend on how you have Neutron configured. We use OpenVSwitch. For OpenVSwitch you want a completely unconfigured interface, for VLANs. If you haven't looked at Server World's tutorial for OpenStack, I would suggest you do so. They can be found here: https://www.server-world.info/en/note?os=Ubuntu_20.04&p=openstack_xena2&f=6 https://www.server-world.info/en/note?os=CentOS_Stream_8&p=openstack_xena2&… Pay particular attention to the names br-eth1 and physnet1, and where and how they are used. You are likely going to need to reference the "Configure Neutron #2" page from the tutorial to understand the whole configuration, as these assume #1 and #2 have been completed (#1 walks through how to setup the support services). The tutorials are for VXLAN, but are modifiable to be VLAN. In particular; [ml2_type_vxlan] vni_ranges = 1:1000 becomes: [ml2_type_vlan] network_vlan_ranges = physnet1:1:1000 For you, I believe that last line would be: network_vlan_ranges = physnet1:684:684 What I can't help you with is how this interacts with PackStack.

Thanks Felipe On Wed, Feb 2, 2022 at 12:21 AM <DHilsbos(a)performair.com> wrote: Felipe; I had significant problems with this as well, when I was first setting up our cluster. The first thing to recognize is that the network type is from the stand point of the host (more specifically from the network services host, and the neutron compute hosts), not the network itself. Your VLAN network is actually a physical network (from the standpoint of the host), because it is bound to a physical interface. If you want to actually use it as a vlan type; a) remove the IP address(es) from the interface(s) of the network and compute host(s), and b) properly configure ml2, or an equivalent plugin.
