Hi, This looks like a bug. When a disk profile is updated, the QoS should be refreshed for all disks that use the profile. Please open a bug and I will look at it.
It is strange, updating a disk without changing anything should not update the QoS. But if it does, than maybe updating the disk using the API would update QoS too: PUT /ovirt-engine/api/disks/123 <disk></disk> Otherwise the only way to refresh QoS is by migrating or restarting the VMs. Best Regards, Andrej On Thu, 15 Nov 2018 at 10:40, Florian Schmid <[email protected]> wrote: > Hi, > > I think, this is definitely a bug. > > In engine.log, I see some of those entries: > 2018-11-15 09:11:02,668Z INFO > [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] > (default task-777) [3670f111-0be3-474a-ae17-f6b826f6948b] EVENT_ID: > USER_UPDATED_QOS(10,114), QoS Dev was updated.
