Scenario Outline: Shared volume
Given a storage class is created with fsType as and shared is set to yes
And pvc is created referencing this storage class and a deployment using the same pvc
And a zfsvolume is created and used by the application
When two pods were deployed on same node and they both are running
Then the LocalPV-ZFS Driver will allow the volumes to be mounted by more than one pods
Examples:
| fsType |
| zfs |
| ext4 |
| xfs |
| btrfs |

Environment:

• LocalPV-ZFS version
• Kubernetes version (use kubectl version):
• Kubernetes installer & version:
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):
