[tc][ptl][infra] Resolution: Mandatory Repository Retirement
by Jeremy Stanley 22 Jul '19

22 Jul '19

When an effort ceases to be an official part (deliverable) of OpenStack with the intent to continue development outside OpenStack's technical governance, the maintainers of that codebase may end up later abandoning it or making other choices at odds with OpenStack policies with no clear indication to consumers. Some folks may have been using it when it was still part of OpenStack, and so may continue to have expectations which are no longer in sync with reality. To solve this, a resolution has been proposed asserting that software which is removed from OpenStack's technical governance in the future can only be continued as a fork, so that its original Git repository in the "openstack" namespace on OpenDev can be retired with a clear message letting consumers of that source code know what has happened and where it has gone. Some breathing room is allowed, as the initial draft includes measures to allow any deliverable repositories which move out of OpenStack prior to the end of the current development cycle (Train) to be renamed into new OpenDev namespaces with a redirect before the new policy goes into effect. The text of the proposed resolution can be found here: https://review.opendev.org/670741 Please follow up on the above review with any comments/concerns, or you can express them as a reply to this ML thread, or in private to me or any other TC members. Thanks for reading! -- Jeremy Stanley

[openstack-ansible][tripleo] creating collaborative acl
by Mohammed Naser 22 Jul '19

22 Jul '19

Hi everyone, I briefly brought this up in the TripleO Ansible meeting however there seems to be more work happening together on OpenStack Ansible roles from the TripleO side (alongside cross-project gating, which is awesome!) Having said that, it seems like we're building more of an upstream relationship to TripleO but I think there is a lot of benefit of making it more of a collaboration between the teams. Therefore, I'd like to propose that we create a Gerrit group called "openstack-ansible-collab". This ACL will be seeded with tripleo-ansible-core and openstack-ansible-core and it will ideally be placed on two initial repositories: - openstack/ansible-config_template - openstack/ansible-role-python_venv_build - openstack/openstack-ansible-os_tempest Those are repositories that are actively being used by TripleO and they are even getting CI tested from TripleO. They make the most sense to start with. TripleO has been around for a while and they have a solid core team that I (personally) feel okay with having core to those repos for now (and more as we work on them together). In terms of governance, these projects will remain under OpenStack-Ansible governance. Please let me know what you think of this proposal? Thanks, Mohammed

Dear Team, Plz clear doubt about cinder control path and data path. If control path goes off and data path continue then still vm continues to use attached volumes.

Hi everyone, I'm thrilled to announce that Guang Yee has agreed to rejoin the keystone core reviewer team. Guang is a former core who was instrumental in many of keystone's key features. We're lucky to have him back to lend his experience and knowledge to our current challenges. Welcome back, Guang! Colleen

[keystone] Shanghai PTG planning
by Colleen Murphy 20 Jul '19

20 Jul '19

Hi team, The foundation has asked us to let them know whether we'll be needing PTG space in Shanghai. The keystone team usually has good attendance at PTGs and makes good use of the time, but I know this next one may be hard for some people to attend so I don't want to automatically assume we'll use it this time. If you wish to attend the next PTG and have a semi-reasonable amount of confidence that you may be able to, please add your name to the etherpad: https://etherpad.openstack.org/p/keystone-shanghai-ptg Please do this by Monday, August 5 so that I have time to respond to the foundation by August 11. Feel free to also start brainstorming topics for the PTG (no deadline on this). Colleen

local storage + remote replication
by Volodymyr Litovka 20 Jul '19

20 Jul '19

Dear colleagues, this question isn't about Openstack, it's rather general question about cloud data storing. It is obvious, that distributed network storage is generally slower than local storage, while is much more reliable. Keeping in mind, that reliability of hardware components became better and better with time (e.g. MTBF of HP DL380G2 is almost 14 years), power systems are reliable enough (if built with reliability in mind), it is safe to say that the most possible source of problems is failure of storage itself, not motherboard or NIC or power supply. Why not to use kind of caching, quickly saving data on local storage, ACKing the operation and replicating changed blocks to remote storage in background during idle time? Having a local RAID1 (with checksums to allow distinguish between failed and correct copy of the data block) + remote replication will give a high speed and enough level of reliability. The only case of temporary slowing down is migration to another node (not pretty often event?) with gradual back replication (from remote storage to local, as the VM will request data) which will last some time from start at new node. Are there serious concerns against such approach? I will appreciate your opinion on this topic. Thank you! -- Volodymyr Litovka "Vision without Execution is Hallucination." -- Thomas Edison
