[NetApp][Ussuri] cifs error since ontap 9.5: Failed to set preferred DC

[Ionut-Madalin Balutoiu]

starting with ONTAP 9.5 I get

And indeed, the ONTAP API for cifs-domain-preferred-dc-add has a new required boolean option "skip-config-validation"

[Impact]
Using new releases of NetApp ONTAP (>= 9.5) leads to the following bug in the Manila code:
https://bugs.launchpad.net/manila/+bug/1887643

As Maurice Escher states, this results in the following error when creating a CIFS share with security service server set to some value:

NetApp API failed. Reason - 13006:Missing input: skip-config-validation

Only Ussuri distro packages are affected by this issue.

This bug can be reproduced only when using `cifs` shares, and only when the driver handles shares servers.

The issue was already fixed upstream, and it's even included in the latest Ussuri minor release: 10.0.2 (or even 10.0.1). Our Ubuntu distro packages install 10.0.0, and do not have this issue fixed.

[Test Case]
* Create an environment with Manila NetApp ONTAP driver and DHSS (driver handles shares enabled). This also requires an external Active Directory for the CIFS shares.
* Create a new Manila CIFS share, given a proper Manila security service defined with the Active Directory info.
* Bug is reproduced.

[Where problems could occur]
If the ontapi_version version was not calculated correctly the skip-config-validation config will result in the same error reported in this bug. Testing this code path will help mitigate this.

Ionut, thanks for this. The patch has been cherry-picked and new package version uploaded to the focal unapproved queue. https://launchpad.net/ubuntu/focal/+queue?queue_state=1&queue_text=manila
Once it lands in focal-proposed it will backport to ussuri-proposed.

Note: we currently don't have an exception for uploading point releases for manila - https://wiki.ubuntu.com/OpenStack/StableReleaseUpdates. We can work on that if we get the right testing in place to regression test new point releases.

Hello Corey,

I've updated the bug description with the [Test Case] needed. I'm happy to test it when the fix is ready.

Hello everyone,

I've tested the new Manila Ussuri packages on Bionic and Focal. The testing was done as described in the `[Test Case]` in the bug description.

The tested packages versions are:
* Bionic - 1:10.0.0-0ubuntu0.20.04.2~cloud0
* Focal - 1:10.0.0-0ubuntu0.20.04.2

Everything works as expected, and the problem doesn't reproduce anymore using the updated Manila Ussuri packages. I'll update the tags.
