[cinder-backup][ceph] cinder-backup support of incremental backup with ceph backend
by Satish Patel 24 May '23

24 May '23

Folks, I have ceph storage for my openstack and configure cinder-volume and cinder-backup service for my disaster solution. I am trying to use the cinder-backup incremental option to save storage space but somehow It doesn't work the way it should work. Whenever I take incremental backup it shows a similar size of original volume. Technically It should be smaller. Question is does ceph support incremental backup with cinder? I am running a Yoga release. $ openstack volume list +--------------------------------------+------------+------------+------+-------------------------------------+ | ID | Name | Status | Size | Attached to | +--------------------------------------+------------+------------+------+-------------------------------------+ | 285a49a6-0e03-49e5-abf1-1c1efbfeb5f2 | spatel-vol | backing-up | 10 | Attached to spatel-foo on /dev/sdc | +--------------------------------------+------------+------------+------+-------------------------------------+ ### Create full backup $ openstack volume backup create --name spatel-vol-backup spatel-vol --force +-------+--------------------------------------+ | Field | Value | +-------+--------------------------------------+ | id | 4351d9d3-85fa-4cd5-b21d-619b3385aefc | | name | spatel-vol-backup | +-------+--------------------------------------+ ### Create incremental $ openstack volume backup create --name spatel-vol-backup-1 --incremental --force spatel-vol +-------+--------------------------------------+ | Field | Value | +-------+--------------------------------------+ | id | 294b58af-771b-4a9f-bb7b-c37a4f84d678 | | name | spatel-vol-backup-1 | +-------+--------------------------------------+ $ openstack volume backup list +--------------------------------------+---------------------+-------------+-----------+------+ | ID | Name | Description | Status | Size | +--------------------------------------+---------------------+-------------+-----------+------+ | 294b58af-771b-4a9f-bb7b-c37a4f84d678 | spatel-vol-backup-1 | None | available | 10 | | 4351d9d3-85fa-4cd5-b21d-619b3385aefc | spatel-vol-backup | None | available | 10 | +--------------------------------------+---------------------+-------------+-----------+------+ My incremental backup still shows 10G size which should be lower compared to the first backup.

[neutron] Deprecate networking-odl project
by Rodolfo Alonso Hernandez 24 May '23

24 May '23

Hello all: During the last releases, the support for "networking-odl" project has decreased. Currently there is no active developer or maintainer in the community. This project depends on https://www.opendaylight.org/; the latest version released is Sulfur (16) while the version still used in the CI is Sodium (11) [1]. I would like first to make a call for developers to update this project. But if this is not possible, I will then start the procedure to deprecate it [2] (**not to retire it**). Regards. [1] https://github.com/openstack/networking-odl/blob/db5c79b3ee5054feb8a17df130… [2] https://docs.openstack.org/project-team-guide/repository.html#deprecating-a…

Designate and neutron - only creating records for floating ips and not servers or ports
by Russell Stather 23 May '23

23 May '23

Hi We have a problem where we can create a floating ip and the neutron integration happily creates the dns record. However, if we create a port or a server the record does not get created. This is a charm installation, with designate using designate-bind as the backend. Any suggestions or places to look would be appreciated. I can't see any errors in the designate logs or the neutron logs. Thanks Russell

Does Openstack have the notion of tenant admin?

Hi, Does Openstack have the notion of tenant admin? If not, can a role be created to simulate such notion?

multi-region deployment
by wodel youchi 23 May '23

23 May '23

Hi, I have been reading about multi-region in openstack. >From my understanding, that keystone and horizon are shared and deployed only in the first region. Is this correct? If yes, what happens if the first region goes down? Regards.

[cinder][dev] Add support in driver - Active/Active High Availability
by U T, Raghavendra 22 May '23

22 May '23

Hi, We wish to add Active/Active High Availability to: 1] HPE 3par driver - cinder/cinder/volume/drivers/hpe/hpe_3par_common.py 2] Nimble driver - cinder/cinder/volume/drivers/hpe/nimble.py Checked documentation at https://docs.openstack.org/cinder/latest/contributor/high_availability.html https://docs.openstack.org/cinder/latest/contributor/high_availability.html… https://docs.openstack.org/cinder/latest/contributor/high_availability.html… Summary of steps: 1] In driver code, set SUPPORTS_ACTIVE_ACTIVE = True 2] Split the method failover_host() into two methods: failover() and failover_completed() 3] In cinder.conf, specify cluster name in [DEFAULT] section cluster = <cluster_name> 4] Configure atleast two nodes in HA and perform testing Is this sufficient or anything else required ? Note: For Nimble driver, replication feature is not yet added. So can the above step 2 be skipped? Appreciate any suggestions / pointers. Regards, Raghavendra Tilay.

Mixing IDE and VIRTIO volumes
by Work Ceph 22 May '23

22 May '23

Hello guys, We have a situation where an image requires an IDE bus in KVM. Therefore, we configured it in OpenStack to have the IDE bus being used. However, when we add new volumes to this VM (server), all of them are being allocated as IDE volumes; therefore, we are limited to 4 volumes in total in the VM. Is it possible to mix different types of volumes in a VM in OpenStack? I know that in other platforms, such as when we use KVM directly, proxmox, Apache CloudStack, we can do such combinations, but we were not able to achieve it in OpenStack. Have you guys worked with similar use cases? I know that I can convert the image to use virtIO or iSCSI bus, and to do that I need to fix/patch the operating system inside the image. However, I would like to check if there is a method to use a root volume of a VM as IDE, and other volumes as virtio to avoid the limit of volumes that IDE has.
