Overcommit setting in NetApp ONTAP SAN Driver

[seiyatakei]

Is this a BUG REPORT or FEATURE REQUEST?:

/kind feature

What happened: Even though driver config "provisioningPolicy" is set to "thin", I cannot create volumes over capacity of aggregate.

What you expected to happen: The driver can overcommit when provisioning volumes.

How to reproduce it (as minimally and precisely as possible):

• Set "provisioningPolicy" in "/etc/opensds/driver/netapp_ontap_san.yaml" to "thin"
• Try to create volume over capacity of aggregate.

Anything else we need to know?:

Environment:

• Hotpot(release/branch) version: v0.10.0(Daito Release)
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:

Maybe the thin support for NetApp is not available from SODA. @himanshuvar please check this and plan to fix

I think one of the solution is to add variable like OpenStack Cinder for overcommit. Cinder has variable "max_over_subscription_ratio" to allow provisioning volume over capacity of pool.

@seiyatakei Right. We will analyze this and add as required. Thanks
