This failure is also prevalent in the upgrade suite:

thanks @ljflores, I also saw that in a different rados suite: https://pulpito.ceph.com/nmordech-2026-02-25_11:36:23-rados-wip-rocky10-branch-of-the-day-2026-02-24-1771941190-distro-default-trial/

and fixed that issue. I was checking the latest rados result which included an updated commit and I don't see the issue there anymore.
