[ovirt-users] 3.6 -> 4.0 upgrade fails on schema refresh

Hi, I'm upgrading to oVirt 4.0 from 3.6.7 and I didn't found any usable solution for this error and rollback: [ ERROR ] schema.sh: FATAL: Cannot execute sql command: --file=/usr/share/ovirt-engine/dbscripts/upgrade/04_00_0140_convert_memory_snapshots_to_disks.sql [ ERROR ] Failed to execute stage 'Misc configuration': Engine schema refresh failed I see one bugreport but it doesn't clear it out for me, is this a known thing ? Thanks, Matt
