This test is for snapshotting an instance/volume and attaching the volume
|
|
created from snapshot to the instance booted from snapshot.
|
|
The following is the scenario outline:
|
|
1. Boot an instance "instance1"
|
|
2. Create a volume "volume1"
|
|
3. Attach volume1 to instance1
|
|
4. Create a filesystem on volume1
|
|
5. Mount volume1
|
|
6. Create a file which timestamp is written in volume1
|
|
7. Unmount volume1
|
|
8. Detach volume1 from instance1
|
|
9. Get a snapshot "snapshot_from_volume" of volume1
|
|
10. Get a snapshot "snapshot_from_instance" of instance1
|
|
11. Boot an instance "instance2" from snapshot_from_instance
|
|
12. Create a volume "volume2" from snapshot_from_volume
|
|
13. Attach volume2 to instance2
|
|
14. Check the existence of a file which created at 6. in volume2
