[ovirt-users] Re: engine-setup failure on 4.1 -> 4.2

Hi all, I have a self hosted engine setup, with 3 servers. I have successfully upgraded several other installations, from 4.1 to 4.2. On one of them I am encountering and issue with the engine-setup. I get the following warning: Found the following problems in PostgreSQL configuration for the Engine database: It is required to be at least '8192' Please note the following required changes in postgresql.conf on 'localhost': 'work_mem' is currently '1024'. It is required to be at least '8192'. postgresql.conf is usually in /var/lib/pgsql/data, /var/opt/rh/rh-postgresql95/lib/pgsql/data, or somewhere under /etc/postgresql* . You have to restart PostgreSQL after making these changes. The database requires these configurations values to be changed. Setup can fix them for you or abort. Fix automatically? (Yes, No) [Yes]: Then, if I select Yes to proceed, I get: [WARNING] This release requires PostgreSQL server 9.5.14 but the engine database is currently hosted on PostgreSQL server 9.2.24. Then finally: [ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode. In that case you should put the system into the "Global Maintenance" mode before running engine-setup, or the hosted-engine HA agent might kill the machine, which might corrupt your data. [ ERROR ] Failed to execute stage 'Setup validation': Hosted Engine setup detected, but Global Maintenance is not set. [ INFO ] Stage: Clean up Log file is located at /var/log/ovirt-engine/setup/ovirt-engine-setup-20190725124653-hvekp2.log [ INFO ] Generating answer file '/var/lib/ovirt-engine/setup/answers/20190725125154-setup.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Execution of setup failed I have put the cluster on global maintenance, though the engine thinks it is not. Are any steps that I may follow to avoid above? I am attaching also the last full setup log. Thank you! Alex
