Yes, 1%% is smth we're fighting for years, as this setting changes on the swift side from time to time, and I really lost account which one is valid at the moment.

Here's related SWIFT bug:

https://bugs.launchpad.net/swift/+bug/1844368

I've just pushed https://review.opendev.org/c/openstack/openstack-ansible-os_swift/+/782117 to cover this issue. Can you try applying this change manually to see if this works?

Hi Dmitriy,
thanks for your answer! Yes, we do use swift and its use as glance backend is
intentional.

I got the following from the swift-proxy-server logs in the swift container on
the infra host after taking a snapshot:

Mar 22 08:43:43 infra1-swift-proxy-container-27169fa7 proxy-server[87]: Client

On the swift host some services logs contain errors. E.g. the
swift-container-updater service:

Mar 22 08:42:19 bc1bl12 systemd[1]: swift-container-updater.service: Main
process exited, code=exited, status=1/FAILURE

The same exit-code and traceback shows in the logs of swift-container-auditor,
swift-account-auditor and swift-account-reaper services. Does this tell you
anything useful?

We didn't experience any problems when uploading files to containers, only when
taking snapshots of instances.

Kind regards,
Oliver

Hi Olver,

Am I right that you're also using OpenStack Swift and it's intentional to
store images there?
Since the issue is related to the upload process into the Swift. So also
checking Swift logs
be usefull as well.
