My 3.3.3 setup was very basic so my testing was not extremely extensive, but I wanted to make sure I could still override NFS mount options (I could) to ensure use of RDMA. Now I'd like to downgrade, but that was not as simple as I'd hoped. I could not find any definitive docs on the subject so pieced together the steps. # Backup 3.3.3 $ engine-backup --mode=backup --scope=all --file=engine-20140211-1457.tar.bz2 --log=engine-backup.log # Enabled the 3.4.0 repo per release notes $ yum update ovirt-engine-setup $ engine-setup # I tested 3.4.0 and wanted to "downgrade". $ engine-backup --mode=restore --scope=all --file=engine-20140211-1457.tar.bz2 --log=engine-backup.log FATAL: Engine service is active - can not restore backup $ /etc/init.d/ovirt-engine stop $ engine-backup --mode=restore --scope=all --file=engine-20140211-1457.tar.bz2 --log=engine-backup.log Restoring...

FATAL: Database is not empty Attached are the two engine-cleanup logs from both attempts. The first (from 20140211) was answering "Yes" only to "remove Engine DB content". The second (from 20140212, today) was "Yes" to "remove all components".
