Public bug reported: In documentations mentioned that size_iops_sec is "burst bucket size"
https://docs.openstack.org/cinder/latest/admin/basic-volume-qos.html but in libvirt documentations is: "The optional size_iops_sec element is the size of I/O operations per second" https://libvirt.org/formatdomain.html and in qemu documentations "iops-size" described as "This setting specifies the size (in bytes) of an I/O request for accounting purposes. Larger requests will be counted proportionally to this size." https://github.com/qemu/qemu/blob/master/docs/throttle.txt so I think it is not related to burst bucket size. and of course we do not have support for *_max_length parameters for burst duration in nova. ** Affects: nova Importance: Undecided Status: New ** Summary changed: - size_iops_sec does behaves different that mentioned in docs + size_iops_sec does behave different than mentioned in docs -- You received this bug notification because you are a member of Yahoo!
