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

[Arik Hadas]

Hi,

This is a bit aggressive solution to remove all snapshots with the memory.

Can you confirm that a storage domain that was active while creating the snapshot with memory was removed from the system?
This is something that was not covered and could lead to the reported issue.

Until we come up with a proper solution, you can use the following query to identify the exact problematic snapshots and remove them before upgrading:
select vm_name, snapshots.description as snapshot_name, snapshot_id from snapshots join vm_static on vm_id=vm_guid where CAST(split_part(memory_volume, ',', 1) AS UUID) not in (select id from storage_domain_static);

Regards,
Arik
