Test to verify if VSAN storage capabilities specified in storage-class is being honored while volume creation.
|

Valid VSAN storage capabilities are mentioned below:
|
||||
1. hostFailuresToTolerate
|
||||
2. forceProvisioning
|
||||
3. cacheReservation
|
||||
4. diskStripes
|

5. objectSpaceReservation
|
||||
6. iopsLimit
|
||||
|
||||
Steps
|
||||
1. Create StorageClass with VSAN storage capabilities set to valid values.
|
||||
2. Create PVC which uses the StorageClass created in step 1.
|
||||
3. Wait for PV to be provisioned.
|
||||
4. Wait for PVC's status to become Bound
|
||||
5. Create pod using PVC on specific node.
|
||||
6. Wait for Disk to be attached to the node.
|
||||
7. Delete pod and Wait for Volume Disk to be detached from the Node.
|
||||
8. Delete PVC, PV and Storage Class
