[ironic] Why do we support RAID level 2?
by Dmitry Tantsur 14 Dec '23

14 Dec '23

Hi folks, I was going through our RAID support and noticed that we declare support for RAID level 2. Per wikipedia [1] it's an extremely rarely used level which offers little benefits. Does anyone remember why we use that? Will anyone cry if we drop it? My worry is officially supporting something that nobody can even test because of lack of hardware or real use case behind it.

[cinder]Cannot create volume from snapshot

Hello guys. I am using Openstack Yoga and Dell Powerstore 5000T When I create volume from a snapshot then I encounter this error cinder.volume.drivers.dell_emc.powerstore.client [req-3384117a-0832-4983-96aa-fd701d68c8eb 6371ebfe0fce499983b1f07e7c34bf6d 4f6902ccd37f4e8f8a1a910641845866 - - -] REST Response: 422 with data {"messages":[{"code":"0xE0A040010003","severity":"Error","message_l10n":"The clone cannot be created because the max number of clones: 32, in a family has been reached.","arguments":["32"]}]} ERROR cinder.volume.drivers.dell_emc.powerstore.client [req-3384117a-0832-4983-96aa-fd701d68c8eb 6371ebfe0fce499983b1f07e7c34bf6d 4f6902ccd37f4e8f8a1a910641845866 - - -] Failed to create clone volume-cc1fdd0b-8dd7-41a2-b63e-1f Do we have any guide about this?

[taskflow][all] Taskflow still using removed asyncore
by Thomas Goirand 14 Dec '23

14 Dec '23

Hi, As per this document: https://docs.python.org/3/whatsnew/3.12.html > Removed > asynchat and asyncore > > These two modules have been removed according to the schedule in > PEP 594, having been deprecated in Python 3.6. Use asyncio instead. > (Contributed by Nikita Sobolev in gh-96580.) Therefore, building the taskflow package (and many other packages that depends on it, like Cinder) fails. Can someone write a patch to get rid of the use of asyncore? Will using asincio instead fail because of our use of Eventlet? Cheers, Thomas Goirand (zigo)

RE: openstack-discuss Digest, Vol 62, Issue 44 Neutron - Issue Urgent
by Asma Naz Shariq 14 Dec '23

14 Dec '23

Hi Openstack Neutron Team, I have deployed Multinode cluster of Openstack through kolla-ansible zed release. The problem I am facing is instances created cannot pick any Ip addresses( Rather than loop back ip or ipv6 addresses) from the assigned networks which I have created provider and self-service flat network type. Hence, I may not be able to ping and ssh instance from the controller node and these instances won’t be able to connect to the internet. Can you guide me how to resolve these issues related to network connectivity so I may able to send you the required files to troubleshoot easily?

The children of Glance images usually are (Cinder) volumes, which therefore live in a different RBD pool "volumes". But if such children do exist a 500 error is thrown by Glance API. There also is an bug about this issue on Launchpad [3]. Manually using the RBD client shows the same error: > # rbd -n client.glance -k /etc/ceph/ceph.client.glance.keyring -p > images children $IMAGE_ID > > 2023-12-13T16:51:48.131+0000 7f198cf4e640 -1 > librbd::image::OpenRequest: failed to retrieve name: (1) Operation not > permitted > 2023-12-13T16:51:48.131+0000 7f198d74f640 -1 librbd::ImageState: > 0x5639fdd5af60 failed to open image: (1) Operation not permitted > rbd: listing children failed: (1) Operation not permitted > 2023-12-13T16:51:48.131+0000 7f1990c474c0 -1 librbd::api::Image: > list_descendants: failed to open descendant b7078ed7ace50d from pool > instances:(1) Operation not permitted So it's a permission error. Following either the documentation of Glance [1] or Ceph [2] on configuring the ceph auth caps there is no mention of granting anything towards the volume pool to Glance. So this is what I currently have configured: > client.cinder > key: REACTED > caps: [mgr] profile rbd pool=volumes, profile rbd-read-only > pool=images > caps: [mon] profile rbd > caps: [osd] profile rbd pool=volumes, profile rbd-read-only > pool=images > > client.glance > key: REACTED > caps: [mgr] profile rbd pool=images > caps: [mon] profile rbd > caps: [osd] profile rbd pool=images > > client.nova > key: REACTED > caps: [mgr] profile rbd pool=instances, profile rbd > pool=images > caps: [mon] profile rbd > caps: [osd] profile rbd pool=instances, profile rbd > pool=images > When granting the glance client e.g. "rbd-read-only" to the volumes pool via: > > # ceph auth caps client.glance mon 'profile rbd' osd 'profile rbd > pool=images, profile rbd-read-only pool=volumes' mgr 'profile rbd > pool=images, profile rbd-read-only pool=volumes' > the error is gone. I am wondering through if this is really just a documentation bug (at OpenStack AND Ceph equally) and if Glance really needs read-only on the whole volumes pool or if there is some other capability that covers asking for child images. All in all I am simply wondering what the correct and least-privilege ceph auth caps for the RBD clients in Cinder, Glance and Nova would look like.

Whenever we do not see a kernel/ramdisk with an image file, we assume it is a whole disk image, and as a result, we don't partition, we only write out what we've been provided.

I realized what was wrong in my case. I have a partition image, and I added the ramdisk and kernel path to 'baremetal_deployment.yaml'. This helped.

openstack cinder client help
by garcetto 13 Dec '23

13 Dec '23

good afternoon, i am trying to use the openstackclient ( https://docs.openstack.org/newton/user-guide/common/cli-install-openstack-c…) but it seems than I cannot use it to see cinder volume snapshot, even the doc say it is possible ( https://docs.openstack.org/python-openstackclient/latest/cli/decoder.html#c… ) [image: image.png] it says " (my-virt-env) user@ostack:~$ openstack snapshot list openstack: 'snapshot list' is not an openstack command. See 'openstack --help'. Did you mean one of these? endpoint add project endpoint create endpoint delete endpoint group add project endpoint group create ... " what am i missing? thank you.

[keystone] Keystone integration with Keycloak
by Franciszek Przewoźny 13 Dec '23

13 Dec '23

Hi all, I'm having some troubles integrating Keystone with Keycloak - pulling username and email from Keycloak using OIDC to Keystone works fine, but pulling groups (list of groups) doesn't. Keycloak provides such data in userinfo (pulled from Google, mapped in Keycloak and added to user): "usergroups": [ "group-a", "group-b", ], Keystone seems to be getting group names, but incorrectly parsing (?) it to a string with commas (instead of semicolon as it's required for multiple group entries to work: https://docs.openstack.org/keystone/latest/admin/federation/mapping_combina…)

[all][tc][cinder] deprecating cinderlib
by Brian Rosmaita 13 Dec '23

13 Dec '23

As discussed at our midcycle meeting last week [0], the Cinder project team hereby announces the deprecation of cinderlib, a library that allows the direct usage of Cinder backend drivers without the cinder services. Cinderlib is a cycle-trailing release, and thus this announcement comes on the heels of the 2023.2 (Bobcat) release of cinderlib, which happened just last week. The Cinder project team will continue to support cinderlib in the stable Maintained branches for their normal lifecycles, as specified by the OpenStack Stable Branch Policy: - stable/2023.2: end of maintenance Spring 2025 - stable/2023.1: end of maintenance Fall 2024 - stable/zed: end of maintenance Spring 2024 The stable/victoria through stable/yoga branches are in Unmaintained status. If you have questions or concerns about the deprecation of cinderlib, please reply to this email or leave a comment on the governance patch: https://review.opendev.org/c/openstack/governance/+/903259 Thank you for your attention to this matter.
