[ovirt-users] ERROR: update or delete on table "luns" violates foreign key constraint...

Hi, I have two-node self hosted engine cluster with iscsi shared storage. Every ovirt-engine restart produces the following error in /var/log/ovirt-engine/engine.log. After that engine works without any problems. How to fix it? 2015-12-18 11:33:00,053 ERROR [org.ovirt.engine.core.bll.storage.SyncLunsInfoForBlockStorageDomainCommand] (org.ovirt.thread.pool-8-thread-11) [674068d8] Command 'org.ovirt.engine.core.bll.storage.SyncLunsInfoForBlockStorageDomainCommand' failed: CallableStatementCallback; SQL [{call deletelun(?)}]; ERROR: update or delete on table "luns" violates foreign key constraint "disk_lun_to_lun_fk" on table "disk_lun_map" Detail: Key (lun_id)=(36001405821da830526f48d0a961767c8) is still referenced from table "disk_lun_map".
