[RFE] When restoring from backup using engine-backup and files is included in scope, perform sanity check on ENGINE_HEAP_MAX and ENGINE_HEAP_MIN
Last modified: 2017-09-28 05:41:01 EDT
If you're restoring from backup on a system with more RAM than was available when the backup was created, then /etc/ovirt-engine/engine.conf.d/10-setup-java.conf could possibly contain conflicting values that would cause ovirt-engine to fail to run.
In a production environment, when recovering from backup on a new system, ENGINE_HEAP_MAX="2g" was included in 10-setup-java.conf, while the initial engine-setup configuration set the ENGINE_HEAP_MIN to 4g, causing ovirt-engine to crash on startup for heap issues.
