fixes:
|
|
- The ONTAP drivers ("7mode" and "cmode") have been fixed to not report
|
|
consumed space as "provisioned_capacity_gb". They instead rely on
|
|
the cinder scheduler's calculation of "provisioned_capacity_gb". This
|
|
fixes the oversubscription miscalculations with the ONTAP drivers. This
|
|
bugfix affects all three protocols supported by these drivers
|
|
(iSCSI/FC/NFS).
|
|
upgrade:
|
|
- If using the NetApp ONTAP drivers (7mode/cmode), the configuration value
|
|
for "max_over_subscription_ratio" may need to be increased to
|
|
avoid scheduling problems where storage pools that previously were
|
|
valid to schedule new volumes suddenly appear to be out of space
|
|
to the Cinder scheduler. See
|
|
documentation `here <https://docs.openstack
|
|
.org/cinder/latest/admin/blockstorage-over-subscription.html>`_.
