CI hiccup
by Cédric Jeanneret 21 Jul '21

21 Jul '21

Hello folks, A broadcast to inform you there was some issue in both gerrit (review.opendev.org) and zuul earlier today (around 7am CET). While the issue was corrected in a very short time (thank you Opendev Infra folks!), there was a small issue with zuul - the CI queue got emptied at some point. There was a notification on the IRC: NOTICE: Due to a configuration error unfortunately the Zuul queue was lost. Please recheck any in-flight changes Sooo... yeah. That's about it :). Have a great day all, and be nice to the CI ;) Cheers, C. -- Cédric Jeanneret (He/Him/His) Sr. Software Engineer - OpenStack Platform Deployment Framework TC Red Hat EMEA https://www.redhat.com/

[zun] Disk quota feature
by Cristina Mayo Sarmiento 21 Jul '21

21 Jul '21

Hi, I've installed Openstack Wallaby of Ubuntu 20.04.2. I'm trying to specify quotas in zun containers but the zun-compute log's show this issue: > zun.common.exception.Invalid: Your host does not support disk quota feature. Does exists anyway to solve that? Currently, zun containers can "see" compute node device's mounted in /var completely: > node@compute:~$df -h > Filesystem Size Used Avail Use% Mounted on > udev 126G 0 126G 0% /dev > tmpfs 26G 2.4M 26G 1% /run > /dev/mapper/vg0-lv--root 98G 12G 82G 13% / > tmpfs 126G 0 126G 0% /dev/shm > tmpfs 5.0M 0 5.0M 0% /run/lock > tmpfs 126G 0 126G 0% /sys/fs/cgroup > /dev/sda3 976M 203M 707M 23% /boot > /dev/sda1 511M 7.9M 504M 2% /boot/efi > /dev/mapper/vg0-lv--var 2.9T 965M 2.8T 1% /var > /dev/loop0 56M 56M 0 100% /snap/core18/2074 > /dev/loop2 68M 68M 0 100% /snap/lxd/20326 > /dev/loop1 56M 56M 0 100% /snap/core18/1944 > /dev/loop3 32M 32M 0 100% /snap/snapd/10707 > /dev/loop5 33M 33M 0 100% /snap/snapd/12398 > /dev/loop4 70M 70M 0 100% /snap/lxd/19188 > tmpfs 26G 0 26G 0% /run/user/1000 > overlay 2.9T 965M 2.8T 1% /var/lib/docker/overlay2/0f88afac44d7a661c31d6b7eea85240a2ed8d84aec057f7f761be4a544d1e089/merged > shm 64M 0 64M 0% /var/lib/docker/containers/a4d60834a7ad753bc2971a446dd65c8acabf4d6df074eec846af0ddb2efc84c9/mounts/shm > test@container:~$df -h > df -h > Filesystem Size Used Available Use% Mounted on > overlay 2.9T 964.3M 2.7T 0% / > tmpfs 64.0M 0 64.0M 0% /dev > tmpfs 125.9G 0 125.9G 0% /sys/fs/cgroup > /dev/mapper/vg0-lv--var > 2.9T 964.3M 2.7T 0% /etc/resolv.conf > /dev/mapper/vg0-lv--var > 2.9T 964.3M 2.7T 0% /etc/hostname > /dev/mapper/vg0-lv--var > 2.9T 964.3M 2.7T 0% /etc/hosts > shm 64.0M 0 64.0M 0% /dev/shm > tmpfs 125.9G 0 125.9G 0% /proc/acpi > tmpfs 64.0M 0 64.0M 0% /proc/kcore > tmpfs 64.0M 0 64.0M 0% /proc/keys > tmpfs 64.0M 0 64.0M 0% /proc/timer_list > tmpfs 64.0M 0 64.0M 0% /proc/sched_debug > tmpfs 125.9G 0 125.9G 0% /proc/scsi > tmpfs 125.9G 0 125.9G 0% /sys/firmware Thanks in advance!

[puppet][TripleO] Is the OpenDev yum-puppetlabs mirror still used?
by Clark Boylan 20 Jul '21

20 Jul '21

Hello, The OpenDev team has been looking at our AFS disk utilization with an eye towards pruning and trimming out content that is no longer used. We've noticed that the yum-puppetlabs mirror [0] is fairly sizeable [1] and we're wondering if it is still being used. If it is still being used do you need all of the contents of the mirror or can we trim it back? Currently looks like there is content for older Fedora releases, SLES, and various puppet versions. It also looks like we may not have synced this recently (not sure why yet). Any info you can provide on how this is used is much appreciated.

[dev][infra][tact-sig] Dropping debian-stretch images from OpenDev
by Jeremy Stanley 20 Jul '21

20 Jul '21

Due to storage pressure in a variety of our subsystems (node images, caches, package mirrors) we're looking at under-utilized aging platforms with an eye for cleaning those up to free some space and reduce our management overhead. High on that list are our debian-stretch nodes and associated mirroring. Stretch was released over four years ago, and became effectively obsolete when Buster was released two years ago. It reached normal EOL one year ago and has limited LTS for only another eleven months. We've had newer debian-buster images available in OpenDev for a couple of years already, and more recently debian-bullseye which is due to be officially released soon. Almost nothing uses the debian-stretch label in master branch configs according to codesearch, though I expect some projects are still relying on it to perform tests on a few of their older stable branches. They may also be relying on the inappropriately-named "debian-stable" nodeset which is based on debian-stretch, though again I see a very low incidence of it in master branches at least. If we were to drop our debian-stretch nodes and debian-stable nodeset definition, how much of an impact would it be on projects? Would a few weeks be enough time for those affected to prepare, or should we be thinking more on the order of months? -- Jeremy Stanley

[openstack-ansible] Configure API endpoints on port 443
by Gilles Mocellin 20 Jul '21

20 Jul '21

Hi OSA users, Does someone have a guide to configure a deployment via openstack-ansible and have all API endpoints on HTTPS/443 ? Of course to distinguish the services, we should user either : - DNS names : https://image.endpointdomain.tld, https:// compute.endpointdomain.tld... - URI : https://endpointdomain.tld/image, https://endpointdomain.tld/ compute... As I understand, HAproxy configuration is really different for these cases only one frontend instead of on by service ?

Dears, As discussed during today's meeting [1], I have reserved the October 19 (Tuesday) 07-09 UTC timeslot in the Bexar Zoom room. I have also kickstarted the etherpad for the PTG. Please feel free to add your discussion topics. Finally, please remember to register for the PTG itself.

[TripleO] Yoga PTG timeslots vote
by Marios Andreou 20 Jul '21

20 Jul '21

Hello TripleO in case you missed the announcement from Ashlee at [1] the yoga ptg will be on October 18-22. We need to decide on the timeslot to use so we can reserve a room to meet. I started a doodle poll at [2] please indicate which time works best for you. The times in the doodle poll are UTC so you need to work out what it means for your location. I arbitrarily chose tuesday 19th but same times will apply to all days. In the last two virtual PTGs used the 1300-1700 UTC - so sanity check does this time still work best for the majority of our community? Rooms should be reserved by July 21 so lets close this poll on Tue 20 and we can discuss if needed during the scheduled irc meeting on the 20th. thanks, marios [1] http://lists.openstack.org/pipermail/openstack-discuss/2021-July/023540.html [2] https://doodle.com/poll/mre6tghmbntbivdd

Re: Setting bandwidth limit
by Rodolfo Alonso Hernandez 20 Jul '21

20 Jul '21

Hello Felipe: Did you configure both the server and the agent? Probably you configured the server correctly, this is why you can create and apply the QoS policies. But you also need to configure the OVS agent [1]. In the plugin ML2 config (by default /etc/neutron/plugins/ml2/ml2_conf.ini), you need to configure the agent extension: [agent]extensions = qos Check this config file and then enable the OVS agent debug logs (restarting the agent). Check the logs for any QoS message there. You should also check: - For BW limit ingress rules (ingress from the VM point of view, this is the default point of view): the OVS agent creates a QoS register and a queue register in the OVS DB table. You should see them using ovs-vsctl tool. - For BW limit egress: the OVS agent modifies the port Interface table, setting the "ingress_policing_rate" and "ingress_policing_burst" (we don't do traffic shaping, we drop packets exceeding the max rate but it works). I hope that helps you to debug what is happening there. Regards.
