[nova][cinder] future of rebuild without reimaging
by Bence Romsics 06 Apr '23

06 Apr '23

Hi All! We have users who use 'rebuild' on volume booted servers before nova microversion 2.93, relying on the behavior that it keeps the volume as is. And they would like to keep doing this even after the openstack distro moves to a(n at least) zed base (sometime in the future). As a naive user, it seems to me both behaviors make sense. I can easily imagine use cases for rebuild with and without reimaging. However since the implementation of https://specs.openstack.org/openstack/nova-specs/specs/zed/implemented/volu… rebuild without reimaging is only possible using an old microversion (<2.93). With that change merged, rebuild without reimaging seems to be a somewhat less than fully supported feature. A few examples of what I mean by that: First, there's this warning: https://opendev.org/openstack/python-openstackclient/src/commit/5eb89e4ca1c… In which it is unclear to me what exactly will become an error in a future release. Rebuild with a different image? Or any rebuild with microversion <2.93? Then old nova microversions may get dropped. Though what I heard from nova folks, this is unlikely to happen. Then there are a few hypothetical situations like: a) Rebuild gets a new api feature (in a new microversion) which can never be combined with the do-not-reimage behavior. b) Rebuild may have a bug, whose fix requires a microversion bump. This again can never be combined with the old behavior. What do you think, are these concerns purely theoretical or real? If we would like to keep having rebuild without reimaging, can we rely on the old microversion indefinitely? Alternatively shall we propose and implement a nova spec to explicitly expose the choice in the rebuild api (just to express the idea: osc server rebuild --reimage|--no-reimage)? If the topic is worth further discussion beyond the ML, I can also bring it to the nova ptg. Thanks in advance, Bence Romsics (rubasov) ps: I'll be afk for a few days, but I'll follow up next Tuesday.

[nova][cinder] Providing ephemeral storage to instances - Cinder or Nova
by Christian Rohmann 04 Apr '23

04 Apr '23

Hello OpenStack-discuss, I am currently looking into how one can provide fast ephemeral storage (backed by local NVME drives) to instances. There seem to be two approaches and I would love to double-check my thoughts and assumptions. 1) *Via Nova* instance storage and the configurable "ephemeral" volume for a flavor a) We currently use Ceph RBD als image_type (https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.im…), so instance images are stored in Ceph, not locally on disk. I believe this setting will also cause ephemeral volumes (destination_local) to be placed on a RBD and not /var/lib/nova/instances? Or is there a setting to set a different backend for local block devices providing "ephemeral" storage? So RBD for the root disk and a local LVM VG for ephemeral? b) Will an ephemeral volume also be migrated when the instance is shutoff as with live-migration? Or will there be an new volume created on the target host? I am asking because I want to avoid syncing 500G or 1T when it's only "ephemeral" and the instance will not expect any data on it on the next boot. c) Is the size of the ephemeral storage for flavors a fixed size or just the upper bound for users? So if I limit this to 1T, will such a flavor always provision a block device with his size? I suppose using LVM this will be thin provisioned anyways? 2) *Via Cinder*, running cinder-volume on each compute node to provide a volume type "ephemeral", using e.g. the LVM driver a) While not really "ephemeral" and bound to the instance lifecycle, this would allow users to provision ephemeral volume just as they need them. I suppose I could use backend specific quotas (https://docs.openstack.org/cinder/latest/cli/cli-cinder-quotas.html#view-bl…) to limit the number of size of such volumes? b) Do I need to use the instance locality filter (https://docs.openstack.org/cinder/latest/contributor/api/cinder.scheduler.f…) then? c) Since a volume will always be bound to a certain host, I suppose this will cause side-effects to instance scheduling? With the volume remaining after an instance has been destroyed (beating the purpose of it being "ephemeral") I suppose any other instance attaching this volume will be scheduling on this very machine? Is there any way around this? Maybe a driver setting to have such volumes "self-destroy" if they are not attached anymore? d) Same question as with Nova: What happens when an instance is live-migrated? Maybe others also have this use case and you can share your solution(s)? Thanks and with regards Christian

[nova][heat] The next steps to "fix" libvirt problems in Ubuntu Jammy
by Takashi Kajinami 03 Apr '23

03 Apr '23

Hello, Since we migrated our jobs from Ubuntu Focal to Ubuntu Jammy, heat gate jobs have become very flaky. Further investigation revealed that the issue is related to something in libvirt from Ubuntu Jammy and that prevents detaching devices from instances[1]. The same problem appears in different jobs[2] and we workaround the problem by disabling some affected jobs. In heat we also disabled some flaky tests but because of this we no longer run basic scenario tests which deploys instance/volume/network in a single stack, which means we lost the quite basic test coverage. My question is, is there anyone in the Nova team working on "fixing" this problem ? We might be able to implement some workaround (like checking status of the instances before attempting to delete it) but this should be fixed in libvirt side IMO, as this looks like a "regression" in Ubuntu Jammy. Probably we should report a bug against the libvirt package in Ubuntu but I'd like to hear some thoughts from the nova team because they are more directly affected by this problem. I'm now trying to set up a centos stream 9 job in Heat repo to see whether this can be reproduced if we use centos stream 9. I've been running that specific scenario test in centos stream 9 jobs in puppet repos but I've never seen this issue, so I suspect the issue is really specific to libvirt in Jammy.

[ptls] PyPI maintainer cleanup - Action needed: Contact extra maintainers
by Jay Faulkner 03 Apr '23

03 Apr '23

Hi PTLs, The TC recently voted[1] to require humans be removed from PyPI access for OpenStack-managed projects. This helps ensure all releases are created via releases team tooling and makes it less likely for a user account compromise to impact OpenStack packages. Many projects have already updated https://etherpad.opendev.org/p/openstack-pypi-maintainers-cleanup#L33 with a list of packages that contain extra maintainers. We'd like to request that PTLs, or their designate, reach out to any extra maintainers listed for projects you are responsible for and request they remove their access in accordance with policy. An example email, and detailed steps to follow have been provided at https://etherpad.opendev.org/p/openstack-pypi-maintainers-cleanup-email-tem… . Thank you for your cooperation as we work to improve our security posture and harden against supply chain attacks. Thank you, Jay Faulkner TC Vice-Chair 1: https://opendev.org/openstack/governance/commit/979e339f899ef62d2a6871a99c9…

[barbican] database is growing and can not be purged
by Pavlo Shchelokovskyy 03 Apr '23

03 Apr '23

Hi all, we are observing the following behavior in Barbican: - OpenStack environment is using both encrypted Cinder volumes and encrypted local storage (lvm) for Nova instances - over the time, the secrets and orders tables are growing - many soft-deleted entries in secrets DB can not be purged by the db cleanup script As I understand what is happening - both Cinder and Nova create secrets in Barbican on behalf of the user when creating an encrypted volume or booting an instance with encrypted local storage. They both do it via castellan library, that under the hood creates orders in Barbican, waits for them to become active and returns to the caller only the ID of the generated secret. When time comes to delete the thing (volume or instance) Cinder/Nova again use castellan, but only delete the secret, not the order (they are not aware that there was any 'order' created anyway). As a result, the orders are left in place, and DB cleanup procedure does not delete soft-deleted secrets when there's an ACTIVE order referencing such secret. This is troublesomes on many levels - users who use Cinder or Nova may not even be aware that they are creating something in Barbican. Orders accumulating like that may eventually result in cryptic errors when e.g. when you run out of quota for orders. And what's more, default Barbican policies do allow 'normal' (creator) users to create an order, but not delete it (only project admin can do it), so even if the users are aware of Barbican involvement, they can not delete those orders manually anyway. Plus there's no good way in API to determine outright which orders are referencing deleted secrets. I see several ways of dealing with that and would like to ask for your opinion on what would be the best one: 1. Amend Barbican API to allow filtering orders by the secrets, when castellan deletes a secret - search for corresponding order and delete it as well, change default policy to actually allow order deletion by the same users who can create them. 2. Cascade-delete orders when deleting secrets - this is easy but probably violates that very policy that disallowed normal users to delete orders. 3. improve the database cleanup so it first marks any order that references a deleted secret also as deleted, so later when time comes both could be purged (or something like that). This also has a similar downside to the previous option by not being explicit enough. I've filed a bug for that https://storyboard.openstack.org/#!/story/2010625 and proposed a patch for option 2 (cascade delete), but would like to ask what would you see as the most appropriate way or may be there's something else that I've missed. Btw, the problem is probably even more pronounced with keypairs - when castellan is used to create those, under the hood both order and container are created besides the actual secrets, and again only the secret ids are returned to the caller. When time comes to delete things, the caller only knows about secret IDs, and can only delete them, leaving both container and order behind. Luckily, I did not find any place across OpenStack that actually creates keypairs using castellan... but the problem is definitely there.

[kolla] Image building question
by Satish Patel 03 Apr '23

03 Apr '23

Folks, I am playing with kolla image building to understand how it works. I am using the following command to build images and wanted to check with you folks if that is the correct way to do it. $ kolla-build -b ubuntu -t source keystone nova neutron glance Does the above command compile code from source or just download images from remote repositories and re-compile them? because in command output I've not noticed anything related to the compiling process going on. Here is the output of all images produced by kolla-build command. Do I need anything else or is this enough to deploy kolla? root@docker-reg:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE kolla/mariadb-server 15.1.0 2a497eee8269 26 minutes ago 595MB kolla/cron 15.1.0 342877f26a8a 30 minutes ago 250MB kolla/memcached 15.1.0 0d19a4902644 31 minutes ago 250MB kolla/mariadb-clustercheck 15.1.0 d84427d3c639 31 minutes ago 314MB kolla/mariadb-base 15.1.0 34447e3e59b6 31 minutes ago 314MB kolla/keepalived 15.1.0 82133b09fbf0 31 minutes ago 260MB kolla/prometheus-memcached-exporter 15.1.0 6c2d605f70ee 31 minutes ago 262MB <none> <none> e66b228c2a07 31 minutes ago 248MB kolla/rabbitmq 15.1.0 8de5c39379d3 32 minutes ago 309MB kolla/fluentd 15.1.0 adfd19027862 33 minutes ago 519MB kolla/haproxy-ssh 15.1.0 514357ac4d36 36 minutes ago 255MB kolla/haproxy 15.1.0 e5b9cfdf6dfc 37 minutes ago 257MB kolla/prometheus-haproxy-exporter 15.1.0 a679f65fd735 37 minutes ago 263MB kolla/prometheus-base 15.1.0 afeff3ed5dce 37 minutes ago 248MB kolla/glance-api 15.1.0 a2241f68f23a 38 minutes ago 1.04GB kolla/glance-base 15.1.0 7286772a03a4 About an hour ago 1.03GB kolla/neutron-infoblox-ipam-agent 15.1.0 f90ffc1a3326 About an hour ago 1.05GB kolla/neutron-server 15.1.0 69c844a2e3a9 About an hour ago 1.05GB kolla/neutron-l3-agent 15.1.0 4d87e6963c96 About an hour ago 1.05GB <none> <none> 486da9a6562e About an hour ago 1.05GB kolla/neutron-linuxbridge-agent 15.1.0 e5b3ca7e099c About an hour ago 1.04GB kolla/neutron-bgp-dragent 15.1.0 ac37377820c6 About an hour ago 1.04GB kolla/ironic-neutron-agent 15.1.0 90993adcd74b About an hour ago 1.04GB kolla/neutron-metadata-agent 15.1.0 8522f147f88d About an hour ago 1.04GB kolla/neutron-sriov-agent 15.1.0 8a92ce7d13c0 About an hour ago 1.04GB kolla/neutron-dhcp-agent 15.1.0 5c214b0171f5 About an hour ago 1.04GB kolla/neutron-metering-agent 15.1.0 7b3b91ecd77b About an hour ago 1.04GB kolla/neutron-openvswitch-agent 15.1.0 1f8807308814 About an hour ago 1.04GB kolla/neutron-base 15.1.0 f85b6a2e2725 About an hour ago 1.04GB kolla/nova-libvirt 15.1.0 0f3ecefe4752 About an hour ago 987MB kolla/nova-compute 15.1.0 241b7e7fafbe About an hour ago 1.47GB kolla/nova-spicehtml5proxy 15.1.0 b740820a7ad1 About an hour ago 1.15GB kolla/nova-novncproxy 15.1.0 1ba2f443d5c3 About an hour ago 1.22GB kolla/nova-compute-ironic 15.1.0 716612107532 About an hour ago 1.12GB kolla/nova-ssh 15.1.0 ae2397f4e1c1 About an hour ago 1.11GB kolla/nova-api 15.1.0 2aef02667ff8 About an hour ago 1.11GB kolla/nova-conductor 15.1.0 6f1da3400901 About an hour ago 1.11GB kolla/nova-scheduler 15.1.0 628326776b1d About an hour ago 1.11GB kolla/nova-serialproxy 15.1.0 28eb7a4a13f8 About an hour ago 1.11GB kolla/nova-base 15.1.0 e47420013283 About an hour ago 1.11GB kolla/keystone 15.1.0 e5530d829d5f 2 hours ago 947MB kolla/keystone-ssh 15.1.0 eaa7e3f3985a 2 hours ago 953MB kolla/keystone-fernet 15.1.0 8a4fa24853a8 2 hours ago 951MB kolla/keystone-base 15.1.0 b6f9562364a9 2 hours ago 945MB kolla/barbican-base 15.1.0 b2fdef1afb44 2 hours ago 915MB kolla/barbican-keystone-listener 15.1.0 58bd59de2c63 2 hours ago 915MB kolla/openstack-base 15.1.0 c805b4b3b1c1 2 hours ago 893MB kolla/base 15.1.0 f68e9ef3dd30 2 hours ago 248MB registry 2 8db46f9d7550 19 hours ago 24.2MB ubuntu 22.04 08d22c0ceb15 3 weeks ago 77.8MB
