Comment 1 Peter Hudec 2018-08-22 21:52:52 UTC
see the notes on github issue for one backup SW

https://github.com/openbacchus/bacchus/issues/30

When I add VM disk checking part, it works as expected or as in previous version of ovirt.

disk_attachments_service = vms_service.vm_service(vm.id).disk_attachments_service()
disk_attachments = disk_attachments_service.list()
for disk_attachment in disk_attachments:
    disk = connection.follow_link(disk_attachment.disk)
    print("DISK %s: %s" % (disk.name, disk.status))
    while disk.status != types.DiskStatus.OK:
        time.sleep(1)
        disk = connection.follow_link(disk_attachment.disk)
        print("DISK %s: %s" % (disk.name, disk.status))

Anything changed in disk locking recently?
AFAIK there was no change on virt side in any 4.2.z at least

Seems like a duplicate of 1628909, from what Arik says it seems to be existing also in 4.1
