I didn't find any of these messages in the larger cloud, at all. The only thing I found in our own is this line matching the timestamp of the validation failure: 192.168.160.9 - - [19/Aug/2025:21:24:39 +0200] "GET /v3/9f743e485e3f477c8935dd29903a1147/volumes/detail HTTP/1.1" 401 114 "-" "cinder-csi-plugin/v1.32.0 gophercloud/v2.5.0" 130959(us) But I don't have an explanation yet why it would fail. I don't manage our k8s infrastructure so I have no idea if anything failed on that side. But I'll try to find out if this had any impact. But again, I found only 3 occurences in total over the last few of weeks, so it doesn't seem to be a real issue for us. Zitat von Eugen Block <eblock@nde.ag>:
I don’t have an answer, I just wanted to share that I see one single message like yours for today. I haven’t checked older logs yet, I’ll take another look when I find the time. This cluster (Caracal) is not that heavily used, though. But I have access to another cluster which is larger than ours and with way more traffic. I will take a look there as well. But they’re running on Victoria…

Hi all, has really no one else seen this behavior? Keystone logs are still flooded with TokenNotFound: Failed to validate token (≈18k/day). I already verified: * Clock skew and memcached → fine * Disabled token cache (revocation_cache_time = 0) → no effect * keystone_authtoken config → consistent * Nova/Cinder show also InvalidToken at the same time Keystone logs TokenNotFound (but the request ID don't match) Any ideas on what could trigger this in 2024.1 / Keystone 25.0.1 would be very welcome. Best regards, Marc

I am running into an issue with our OpenStack Kolla-Ansible deployment (Release 2024.1, Keystone 25.0.1) where Keystone logs are being flooded (18k per day) with TokenNotFound: Failed to validate token stack traces[1].
From the traceback, it seems these requests are attempting to validate tokens that have already been revoked. The majority of these come from Nova and Cinder, but the request_id from Keystone does not appear in their logs.
Instead of finding the matching requests in Nova or Cinder logs, I only see InvalidToken: Token authorization failed messages[2]. Most of the time, the platform does not show any user-visible issues in these areas, although occasional failures can be observed. Could this indicate an issue with token caching or revocation list synchronization between services? Memcached looks fine. Any ideas what could be triggering this behavior are welcome. If you need more Information please let me know. Thanks in advance.
