| Feature: Validate scheduling algorithm | ||
| Background: | ||
| Given 3 node lvmnode cluster is configured | ||
| And lvm vg "lvmvg" with 20G is created on each node | ||
|
|
||
| Scenario: test CapacityWeighted scheduler logic | ||
| Given sc is created with scheduler parameter set to "CapacityWeighted" | ||
| When "pvc-1" is created using size "5G" | ||
| And "pvc-2" is created using size "5G" | ||
| And "pvc-3" is created using size "2G" | ||
| Then all three pvc lvmvolume should be placed on different nodes | ||
| When "pvc-4" is created with size "1G" | ||
| Then "pvc-4" lvmvolume should be placed on "pvc-3" lvmvolume node | ||
| When "pvc-5" is created with size "1G" | ||
| Then "pvc-5" lvmvolume should be placed on "pvc-3" lvmvolume node | ||
| When "pvc-6" is created with size "2G" | ||
| Then "pvc-6" lvmvolume should be placed on "pvc-3" lvmvolume node | ||
| When "pvc-7" is created with size "3G" | ||
| Then "pvc-7" lvmvolume should be placed on "pvc-1" or "pvc-2" lvmvolume node | ||
| When "pvc-8" is created with size "3G" | ||
| Then "pvc-8" lvmvolume should not be placed on "pvc-7" and "pvc-3" node | ||
|
|
||
| Scenario: test SpaceWeighted with vgextend logic | ||
| Given sc is created by not setting scheduler parameter explicitly | ||
| When "pvc-1" is created with using size "6G" | ||
| And "pvc-2" is created with using size "2G" | ||
| And "pvc-3" is created with using size "3G" | ||
| Then all pvc lvmvolume should be placed on different nodes | ||
| When "pvc-1" vg is extended by 10G | ||
| And "pvc-4" is created with size "5G" | ||
| Then "pvc-4" lvmvolume should be placed on "pvc-1" lvmvolume node | ||
|
|
||
| Scenario: test SpaceWeighted without vgextend logic | ||
| Given sc is created by not setting scheduler parameter explicitly | ||
| When "pvc-1" is created with using size "6G" | ||
| And "pvc-2" is created with using size "2G" | ||
| And "pvc-3" is created with using size "3G" | ||
| Then all pvc lvmvolume should be placed on different nodes | ||
| When "pvc-4" is created with size "5G" | ||
| Then "pvc-4" lvmvolume should be placed on "pvc-2" lvmvolume node | ||
|
|
||
| Scenario: test VolumeWeighted logic | ||
| Given sc is created with scheduler parameter set to "VolumeWeighted" | ||
| When "pvc-1" is created with using size "6G" | ||
| And "pvc-2" is created with using size "2G" | ||
| And "pvc-3" is created with using size "3G" | ||
| Then all pvc lvmvolume should be placed on different nodes | ||
| When "pvc-4" is created with size "4G" | ||
| Then "pvc-4" lvmvolume can be on any node | ||
| When "pvc-5" is created with size "3G" | ||
| Then "pvc-5" lvmvolume can not be on "pvc-4" node | ||
| When "pvc-6" is created with size "6G" | ||
| Then "pvc-6" can not be on "pvc-4" and "pvc-5" lvmvolume node |
