This test calculates latency numbers for volume lifecycle operations

1. Create 4 type of storage classes 2. Read the total number of volumes to be created and volumes per pod 3. Create total PVCs (number of volumes) 4. Create Pods with attached volumes per pod 5. Verify access to the volumes 6. Delete pods and wait for volumes to detach 7. Delete the PVCs

Perform vsphere volume life cycle management at scale based on user configurable value for number of volumes. The following actions will be performed as part of this test.

1. Create Storage Classes of 4 Categories (Default, SC with Non Default Datastore, SC with SPBM Policy, SC with VSAN Storage Capalibilies.) 2. Read VCP_SCALE_VOLUME_COUNT, VCP_SCALE_INSTANCES, VCP_SCALE_VOLUMES_PER_POD, VSPHERE_SPBM_POLICY_NAME, VSPHERE_DATASTORE from System Environment. 3. Launch VCP_SCALE_INSTANCES goroutine for creating VCP_SCALE_VOLUME_COUNT volumes. Each goroutine is responsible for create/attach of VCP_SCALE_VOLUME_COUNT/VCP_SCALE_INSTANCES volumes. 4. Read VCP_SCALE_VOLUMES_PER_POD from System Environment. Each pod will be have VCP_SCALE_VOLUMES_PER_POD attached to it. 5. Once all the go routines are completed, we delete all the pods and volumes.

Functions

func DeleteCinderVolume

func DeleteCinderVolume(name string) error

func PerformVolumeLifeCycleInParallel

func PerformVolumeLifeCycleInParallel(f *framework.Framework, client clientset.Interface, namespace string, instanceId string, sc *storageV1.StorageClass, iterations int, wg *sync.WaitGroup)

goroutine to perform volume lifecycle operations in parallel

func SIGDescribe

func SIGDescribe(text string, body func()) bool

func SkipUnlessLocalSSDExists

func SkipUnlessLocalSSDExists(ssdInterface, filesystemType string, node *v1.Node)

SkipUnlessLocalSSDExists takes in an ssdInterface (scsi/nvme) and a filesystemType (fs/block) and skips if a disk of that type does not exist on the node

func VolumeCreateAndAttach

func VolumeCreateAndAttach(client clientset.Interface, namespace string, sc []*storageV1.StorageClass, volumeCountPerInstance int, volumesPerPod int, nodeSelectorList []*NodeSelector, nodeVolumeMapChan chan map[string][]string, vsp *vsphere.VSphere)

VolumeCreateAndAttach peforms create and attach operations of vSphere persistent volumes at scale

Types

type NodeSelector

type NodeSelector struct {
	// contains filtered or unexported fields
}

NodeSelector holds
