Hello, first make sure that the service log files are rotating, should be. psql database has some limitations, the notable one is that it always grows. there are automatic procedures that are called vacuum, which reclaim space. when vacuum is running there is significant slow down, so these are not run often. if you have storage constraint maybe you need to increase the auto vacuum interval[1], or run manually[2] in the past using other applications I found up that there is lower downtime when simply stopping application and performing backup/restore of the database. but in case of ovirt-engine this option is not valid.
