Hello all, first of all thank you very much for this stable virtualization environment. It has been a pillar for our company’s business for more than 5 years now and after migrating from version 3 to 4 it has been so stable ever since. Anyway, I ran into a problem I cannot fix on my own yesterday: After a lot of consideration and hesitation since this is a production environment I followed the upgrade guide (https://www.ovirt.org/documentation/upgrade_guide/), configured a vanilla CentOS 8 server as controller, decommissioned the old 4.3 controller and fired up the new one. It worked like a charm until I tried to migrate VMs, start new ones or even create new disks. We use Ceph as managed storage, providing a SSD only and a HDD only pool. The UI simply told me that there was an error. I started investigating the issue and found corresponding log entries in ovirt-engine.log: 2021-03-22 10:36:37,247+01 ERROR [org.ovirt.engine.core.common.utils.cinderlib.CinderlibExecutor] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-24) [67bf193c] cinderlib execution failed: But that was all the engine had to say about the issue. There was no stack trace or additional information. There is no logfile in /var/log/ovirt-engine/cinderlib/, the directory simply is empty while on the other controller it was frequently filed with annoying „already mounted“ messages. Can anyone help me with that issue? I searched the web for a solution or someone else with the same problem, but came up empty. Is there a way to turn up the log level for cinderlib? Are there any dependencies I have to install besides the ovirt packages? Any help is very much appreciated!

Hello all, hello Benny, thank you very much for the helpful answer and pointing me to the documentation. After setting up the server from scratch, installing some dependencies and fixing the issue of a missing __DEFAULT__ volume type in the ovirt_cinderlib database I hit a new bump: psycopg2.ProgrammingError: column volumes.service_uuid does not exist The /var/log/ovirt-engine/cinderlib/cinderlib.log file contains a somewhat lengthy entry of a failed SQL query basically telling me that the database structure is not what is expected by ovirt. I upgraded from 4.3 to 4.4 using the backup/restore upgrade method and would have thought oVirt’s engine-setup had migrated the database to a new model. Do I have to execute some upgrade command manually? Kind regards and thanks for all the help, Marc -- ________________________________________________________________________ Dipl.-Inform.
