Bug Description
The driver is broken, reporting incorrectly the backends free capacities, as an infinite resource.
This causes two main problems:
- the scheduler always chooses the same netapp backend, and isn´t making any balance between the different backends.
- If the first storage backend has no real free capacity, the driver chooses it anyway, therefore after 3 schedule attemps, the volume creation stops with an error.
Is it possible to fix the driver, in order to report the real backends free capacity, so the scheduler balances the volume creation?
We can attach some log if is necessary.
Thanks in advance.
Agustin.
