Hi all, i just upgraded a cluster from 4.3.10 to 4.5.4. 3 hosts, hosted-engine, engine deployment via shell and with restore from backup. Engine update worked fine, but host update from 4.4.10 to 4.5.4 failed because the engine could not initiate a host reboot: 2023-10-10 13:37:27,802+02 WARN [org.ovirt.engine.core.dal.job.ExecutionMessageDirector] (EE-ManagedThreadFactory-engine-Thread-2) [7d4d6 a58] The message key 'SshHostReboot' is missing from 'bundles/ExecutionMessages' 2023-10-10 13:37:27,823+02 INFO [org.ovirt.engine.core.bll.SshHostRebootCommand] (EE-ManagedThreadFactory-engine-Thread-2) [7d4d6a58] Running command: SshHostRebootCommand internal: true.

This also happens when a host is reinstalled via engine webinterface. How can i fix this? The only Workaround i found is rebooting the host via SSH and reactivating it via engine webinterface. Also, i constantly find error messages like these in the engine.log: 2023-10-11 13:54:11,338+02 INFO [org.ovirt.engine.extension.aaa.jdbc.core.Authentication] (default task-815) [] locking user: api-user due to interval failures 2023-10-11 13:54:14,932+02 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-812) [] EVENT_ID: USER_VDC_LOGIN_FAILED(114), User api-user@internal connecting from '<engine-ip>' failed to log in : 'Unable to log in because the password has expired.

Please change the password to proceed.. This only affects the user "api-user". I am still new to oVirt and have no idea what the api-user is trying to do and where. I found https://www.ovirt.org/develop/release-management/features/infra/aaa-jdbc.htm... but havent tried resetting yet because i dont know what will be affected by that. Can anyone help to point me in the right direction? Many thanks in advance :) Regards, Niko
