feature:
|
|
- On Mitaka compute nodes, if you want to modify the default disk allocation
|
|
ratio of 1.0, you should set that on every compute node, rather than
|
|
setting it in the scheduler. This means the disk, RAM and CPU allocation
|
|
ratios now all work in the same way.
|
|
upgrade:
|
|
- For Liberty compute nodes, the disk_allocation_ratio works as before, you
|
|
must set it on the scheduler if you want to change it.
|
|
For Mitaka compute nodes, the disk_allocation_ratio set on the compute
|
|
nodes will be used only if the configuration is not set on the scheduler.
|
|
This is to allow, for backwards compatibility, the ability to still
|
|
override the disk allocation ratio by setting the configuration on the
|
|
scheduler node.
|
|
In Newton, we plan to remove the ability to set the disk allocation ratio
|
|
on the scheduler, at which point the compute nodes will always define the
|
|
disk allocation ratio, and pass that up to the scheduler. None of this
|
|
changes the default disk allocation ratio of 1.0. This matches the
|
|
behaviour of the RAM and CPU allocation ratios.
