[kolla] Ussuri -source images now use stable branches tarballs
by Michał Nasiadka 23 Sep '20

23 Sep '20

Hello, Since [1] was merged - Kolla source type images are using stable branch tarballs for OpenStack projects - compared to latest point releases - as previously. There are some projects though, that kolla-build uses point releases for those, the list can be found in version-check tool source [2]. Users that want to build source images using latest point releases - can run tools/version-check.py with --versioned-releases option (-v) - and it will adapt sources list accordingly.

Hello, After discussion in IRC I booked a slot for Storlets project in the Wallaby vPTG. I created a planning etherpad[1] so please put your name/nick if you are interested to join , and also put any topics you want to discuss there. [1] https://etherpad.opendev.org/p/storlets-ptg-wallaby Currently we have a slot from 13:00 UTC booked, but if we don't see attendance from EMEA/NA, we might reschedule it to "earlier" slots since current active cores are based in APAC. Please let me know if you have any questions. Thank you Takashi

[all][elections][tc] Stepping down from the TC
by Nate Johnston 22 Sep '20

22 Sep '20

All, I have decided not to run for reelection to the TC. Although I remain a part of the OpenStack community my responsibilities have shifted away from engineering, and I strongly believe that the TC should be composed of people who are actively creating or operating OpenStack on a daily basis. I am deeply appreciative for all of the support I have recieved from current and former TC members. I also want to take this chance to tell my story a bit, in hopes that it will encourage others to participate more with the TC. A year ago when I joined the TC I did not have a clear idea what to expect. I had observed a few TC meetings and brought one issue to the TC's attention, but since I did not have background on the workstreams in progress, there was a lot that I did not understand or could not contextualize. So what I did was observe, gathering an understanding of the issues and initiatives and raising my hand to participate when I felt like my efforts could make a difference. I was pleasantly surprised how many times I was able to raise my hand and work on things like community goals or proposals like distributed project leadership. The fact that I have not been around since the beginning - my first significant code contributions were merged in the Mitaka cycle - and I did not already know all the names and histories did not matter much. What mattered was a willingness to actively engage, to participate in thoughtful discernment, and when the opportunity presented itself to put in the work. I feel like I made a difference. And if you don't feel the calling to join the TC, that is fine too. Be a part of the process - join the meetings, discuss the issues that cut across projects, and have your voice heard. If you are a part of creting or using OpenStack then you are a part of the TC's constituency and the meetings are to serve you. You don't have to be a member of the TC to participate in the process. Thanks so much, Nate Johnston

Re: Ussuri CentOS 8 add mptsas driver to introspection initramfs

Hi, thanks a lot. That did the trick. Now it loads the module automatically. I even added another driver and it works like a charm. :) Best Regards, Oliver Am 15.

[openstack][cinder] volume_copy_bps_limit
by Ignazio Cassano 22 Sep '20

22 Sep '20

Hello stackers, I am using cinder netapp nfs driver and I have vm performances problems during the backup of volumes. My backup tool make snapshots of volumes, then, on compute notes, it use virt-convert for creating a volume backup on another nfs backend using a different vlan. But during the virt-convert a lot of read are done on netapp and my virtual machines become very slow. I am asking if volume_copy_bps_limit can help me to mitigate. Please, anyone could help me ?
