Description Lukas Bezdicka 2023-08-02 10:55:17 UTC

During investigation of OSP-26886 we noticed that fix for #2186892 introduced breaking change for upgrade.


From now on nova_compute needs to use service_user but that is not set up during the controller upgrade. This blocks volume operations on the cloud breaking the upgrade.

We need to provide nova service_user setting during switch to the hybrid mode of nova_compute.

Comment 4 Lukas Bezdicka 2023-08-09 11:06:43 UTC

I concluded that best WA for this for now is to simply apply the patch on Undercloud before running upgrade prepare.

FAILED QA investigating

Comment 11 Lukas Bezdicka 2023-09-07 07:45:13 UTC

We verified that it does set service token and nova compute sends service token. Failure in CI is some new issue that needs new BZ.
