Add dynamic secondary storage selection by BryanMLima · Pull Request #7659 · apache/cloudstack

BryanMLima · 2023-06-20T19:33:26Z

Description

This PR aims to add the possibility to direct resources (Volumes, Templates, Snapshots and ISOs) to a specific secondary storage through rules written in JavaScript that will only affect new allocated resources. This feature is fully described in issue #7654.

Fixes: #7654

How Has This Been Tested?

Unit tests were added to validate the functionality of the implemented methods. Besides this, the overall functionality was tested in a local lab with two secondary storage available, creating basic JS rules and validating that the resource was allocated according to the heuristic rule. Below, there are some examples used in the tests, based on the variables available for each resource type specified in the specification of the feature proposal.

Allocate a resource type to a specific secondary storage.

functionfindStorageWithSpecificId(pool){returnpool.id==='7432f961-c602-4e8e-8580-2496ffbbc45d';}secondaryStorages.filter(findStorageWithSpecificId)[0].id

Dedicate storage pools for a type of template format.

functiondirectToDedicatedQCOW2Pool(pool){returnpool.id==='7432f961-c602-4e8e-8580-2496ffbbc45d';}functiondirectToDedicatedVHDPool(pool){returnpool.id==='1ea0109a-299d-4e37-8460-3e9823f9f25c';}if(template.format==='QCOW2'){secondaryStorages.filter(directToDedicatedQCOW2Pool)[0].id}elseif(template.format==='VHD'){secondaryStorages.filter(directToDedicatedVHDPool)[0].id}

Direct snapshot of volumes with the KVM hypervisor to a specific secondary storage.

if(snapshot.hypervisorType==='KVM'){'7432f961-c602-4e8e-8580-2496ffbbc45d';}

Direct resources to a specific domain:

if(account.domain.id=='52d83793-26de-11ec-8dcf-5254005dcdac'){'1ea0109a-299d-4e37-8460-3e9823f9f25c'}elseif(account.domain.id=='c1186146-5ceb-4901-94a1-dd1d24bd849d'){'7432f961-c602-4e8e-8580-2496ffbbc45d'}

I could dedicate a secondary storage for KVM snapshots.
I could dedicate a secondary storage for a domain.
I was unable to dedicate another secondary storage for a second domain in the same zone. I believe this might be a limitation?
I faced the below issues while registering template with the following rules:

@BryanMLima any documentation available that provides some guidance on the usage of this feature? Any plans to implement a UI?

@rajujith currently, the only documentation (more like a feature specification) is described in issue #7654; though, I pretend to add a proper documentation of this feature in the official documentation of CloudStack. Regarding the implementation of the UI for this feature, it is planned, however, it is not a priority at the moment.

@BryanMLima

1. I could dedicate a secondary storage for KVM snapshots.
2. I could dedicate a secondary storage for a domain.
3. I was unable to dedicate another secondary storage for a second domain in the same zone. I believe this might be a limitation?
4. I faced the below issues while registering template with the following rules:

@rajujith thanks for testing this PR.

Regarding item 3), could you provide more details of this testing? This feature only allows one heuristic rule per type, if you tried to dedicate a secondary storage to a domain for a specific type, you need to edit the same heuristic rule to dedicate to another domain.
Concisely, all heuristic rules for a given type should be in the same secondary storage selector, otherwise, an exception will be thrown and the message There is already a heuristic rule in the specified Zone {...} with the type [...]. will be presented.

In the future, this feature could allow multiple heuristic rules for the same type in a zone, allowing operators to specify the order in which each rule would be verified.

Regarding item 4), the description of this PR and the issue presented the uuid for the secondarystorage variable in the JS script; however, it is the id that is provided in the script. I apologise for the confusion, I already fixed this in both the PR and the issue description's.
