15 Oct '21

Hi everyone, The next vPTG will be held on 18-22 October as I shared at the previous IRC meeting [1]. Registration has already opened [2]. We've decided to have the next vPTG session on the same timeslots, 6-8 UTC, as previous for most of us join from India and APAC regions. I've prepared etherpad for the next vPTG [3]. If you have any suggestion, please add your topic on it.

[dev][cinder] Consultation about new cinder-backup features
by Daniel de Oliveira Pereira 15 Oct '21

15 Oct '21

Hello everyone, We have prototyped some new features on Cinder for our clients, and we think that they are nice features and good candidates to be part of upstream Cinder, so we would like to get feedback from OpenStack community about these features and if you would be willing to accept them in upstream OpenStack. Our team implemented the following features for cinder-backup service: 1. A multi-backend backup driver, that allow OpenStack users to choose, via API/CLI/Horizon, which backup driver (Ceph or NFS, in our prototype) will be used during a backup operation to create a new volume backup. 2. An improved NFS backup driver, that allow OpenStack users to back up their volumes to private NFS servers, providing the NFS hostpath at runtime via API/CLI/Horizon, while creating the volume backup. Considering that cinder was configured to use the multi-backend backup driver, this is how it works: During a volume backup operation, the user provides a "location" parameter to indicate which backend will be used, and the backup hostpath, if applicable (for NFS driver), to create the volume backup. For instance: - Creating a backup using Ceph backend: $ openstack volume backup create --name <backup_name> --location ceph <volume_id> - Creating a backup using the improved NFS backend: $ openstack volume backup create --name <backup_name> --location nfs://my.nfs.server:/backups <volume_id> If the user chooses Ceph backend, the Ceph driver will be used to create the backup. If the user chooses the NFS backend, the improved NFS driver, previously mentioned, will be used to create the backup. The backup location, if provided, is stored on Cinder database, and can be seen fetching the backup details: $ openstack volume backup show <backup_name> Briefly, this is how the features were implemented: - Cinder API was updated to add an optional location parameter to "create backup" method. Horizon, and OpenStack and Cinder CLIs were updated accordingly, to handle the new parameter. - Cinder backup controller was updated to handle the backup location parameter, and a validator for the parameter was implemented using the oslo config library. - Cinder backup object model was updated to add a nullable location property, so that the backup location could be stored on cinder database. - a new backup driver base class, that extends BackupDriver and accepts a backup context object, was implemented to handle the backup configuration provided at runtime by the user. This new backup base class requires that the concrete drivers implement a method to validate the backup context (similar to BackupDriver.check_for_setup_error) - the 2 new backup drivers, previously mentioned, were implemented using these new backup base class. - in BackupManager class, the "service" attribute, that on upstream OpenStack holds the backup driver class name, was re-implemented as a factory function that accepts a backup context object and return an instance of a backup driver, according to the backup driver configured on cinder.conf file and the backup context provided at runtime by the user. - All the backup operations continue working as usual. Could you please let us know your thoughts about these features and if you would be open to adding them to upstream Cinder? If yes, we would be willing to submit the specs and work on the upstream implementation, if they are approved. Regards, Daniel Pereira

[masakari] Proposal to cancel weekly meetings
by Radosław Piliszek 06 Oct '21

06 Oct '21

Dears, Due to low attendance and the current schedule being uncomfortable for me, I propose to cancel the weekly meetings and suggest we coordinate via this mailing list and do ad-hoc chats on IRC as I'm simply lurking there most of the time and answering the messages. Kind regards, -yoctozepto

[ironic][molteniron][qa] Anyone still using MoltenIron?
by Julia Kreger 05 Oct '21

05 Oct '21

Out of curiosity, is anyone still using MotltenIron? A little historical context: It was originally tooling that came out of IBM to reserve physical nodes in a CI cluster in order to perform testing. It was never intended to be released as it was tooling *purely* for CI job usage. The reason I'm asking is that the ironic team is considering going ahead and retiring the repository. Thanks! -Julia

Help with eventlet 0.26.1 and dnspython >= 2
by Thomas Goirand 04 Oct '21

04 Oct '21

Hi, As you may know, eventlet is incompatible with dnspython >= 2.0.0.0rc1. See [1] for the details. However, Debian unstable has 2.0.0. Would there be some good soul willing to help me fix this situation? I would need a patch to fix this, but I'm really not sure how to start. Cheers, Thomas Goirand (zigo)
