[Nova] Suggestion needed for detach-boot-volume design
by Zhenyu Zheng 08 Jan '19

08 Jan '19

Hi Nova, Happy New Year! I've been working on detach-boot-volume[1] in Stein, we got the initial design merged and while implementing we have meet some new problems and now I'm amending the spec to cover these new problems[2]. The thing I want to discuss for wider opinion is that in the initial design, we planned to support detach root volume for only STOPPED and SHELVED/SHELVE_OFFLOADED instances. But then we found out that we allowed to detach volumes for RESIZED/PAUSED/SOFT_DELETED instances as well. Should we allow detaching root volume for instances in these status too? Cases like RESIZE could be complicated for the revert resize action, and it also seems unnecesary. Thoughts?

[dev][keystone][nova][oslo] unified limits + oslo.limit interface questions
by Lance Bragstad 08 Jan '19

08 Jan '19

Hi all, Before the holidays there was a bunch of discussion around unified limits and getting that integrated into nova. One of the last hurdles is smoothing out the interface between nova and the oslo.limit library, which John and Jay were helping out with a bunch. There are a couple of WIP patches proposed that attempt to work through this [0][1][2]. Now that people are starting to recover from the holidays, I wanted to start a thread on what remains for this work. Specifically, what can we do to air out the remaining concerns so that we can release a useable version of oslo.limit for services to consume. Thoughts? [0] https://review.openstack.org/#/c/615180/ John's WIP'd integration patch [1] https://review.openstack.org/#/c/602201/ nova specification [2] https://review.openstack.org/#/c/596520/21 XiYuan's patch to sort out the interface from oslo.limit

The spec for huawei ibmc drvier has been post here: https://storyboard.openstack.org/#!/story/2004635 , waiting for review. 2. About the third-party CI part, we provide mocked unittests for our driver's code. Not sure what third-party CI works for in this case. What else we should do? Thanks Qianbiao.NG

[dev] 'sqlalchemy.exc.NoSuchTableError: migration_tmp' errors due to SQLite 3.26.0
by Stephen Finucane 08 Jan '19

08 Jan '19

Just to note that I'm currently unable to run nova unit tests locally on Fedora 29 without downgrading my sqlite package. The error I'm seeing is: sqlalchemy.exc.NoSuchTableError: migration_tmp The root cause appears to be a change in 3.26.0 which is breaking sqlalchemy-migrate, as noted here: https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1807262 Corey Bryant has proposed the patch for this patch, linked below, which should resolve this. Any chance an sqlalchemy-migrate core could look at this before I reach the point of not being able to downgrade my sqlite package and run nova unit tests? :) https://review.openstack.org/#/c/623564/5 Stephen
