• Installation

  1. Validation of installing ZFS-LocalPV provisioner.
  2. Install ZFSPV controller in High Availabilty (HA) and check the behaviour of zvolume when one of the controller replica is down.

• Volume Provisioning

  1. E2e test for succesfully provision and deprovision of the volume. (fsTypes: zfs, xfs, ext4 and btrfs)
  2. E2e test of custom-topology support for ZFSPV set via storage-class.
  3. E2e test for Raw-block-volume support for ZFSPV.

• Zvolume Properties

  1. Verification of zvolume properties set via the storage-class.
  2. Modification of zvolume properties after zvolume creation i.e. at runtime (Properties: compression & dedup)

• Volume Resize

  1. ZFS volume resize test. (File-system: zfs,xfs and ext4)

• Snapshot & clone

  1. E2e test case for ZFS-LocalPV snapshot and clone (File-system: zfs,xfs,ext4 and btrfs)

• Infra-chaos

  1. Testcase for restart of the docker runtime on node where volume is provisioned.
  2. Testcase for restart of kubelet services on node where volume is provisioned.

• Upgrade Testing

  1. Upgrade of the ZFS-LocalPV components and verify that older volume is not impacting with any issue.
  2. Provision of the new volume after upgrading the zfspv-components

• Manual test cases

1. Check for the parent volume; it should not be deleted when volume snapshot is present.
2. Test case for the scheduler to verify it is doing volume count based scheduling.
