Subject: [pve-devel] [PATCH ha-manager 3/3] test: add additional mixed resource affinity rule test cases
Date: Fri, 19 Sep 2025 16:08:11 +0200	[thread overview]
Message-ID: <20250919140856.1361124-4-d.kral@proxmox.com> (raw)
In-Reply-To: <20250919140856.1361124-1-d.kral@proxmox.com>

These first test case shows and documents changes to the case, where
there aren't enough nodes to properly hold the guarantees of strict
resource affinity rules nor are efficiently solved yet.

The second test case shows that the former test case would have needed
four nodes to hold all guarantees and resolve the wrong node placement
in one step.

+The test scenario is:
+- vm:101, vm:102, and vm:103 must be kept together
+- vm:201, vm:202, and vm:203 must be kept together
+- vm:101 and vm:201 must be kept separate
+- Therefore, vm:101, vm:102, and vm:103 must all be kept separate from vm:201,
+  vm:202, and vm:203 and vice versa
+- vm:101, vm:103, vm:201, and vm:203 are currently running on node1
+- vm:102 and vm:202 are both running on node2
+
+The expected outcome is:
+- The resource-node placements do not adhere to the defined resource affinity
+  rules, therefore the HA resources must be moved accordingly. In the end,
+  vm:101, vm:102, and vm:103 should be on a separate node as vm:201, vm:202,
+  and vm:203.
+
+The current final outcome is correct, but is inefficient and doesn't hold all
+guarantees (i.e. do not put resources in strict node affinity rules on the same
+node nor their migration target) at all times. As shown by
+test-resources-affinity-strict-mixed4, it needs at least four nodes to hold all
+guarantees and rebalance the resources to their correct node placements.
