From a989bca592a5beeac6279732d44a2745210e2f6d Mon Sep 17 00:00:00 2001 From: chrislusf Date: Tue, 2 Dec 2025 12:58:30 -0800 Subject: [PATCH] test: add integration tests for EC disk type support Add integration tests to verify the -diskType flag works correctly: - TestECDiskTypeSupport: Tests EC encode and balance with SSD disk type - TestECDiskTypeMixedCluster: Tests EC operations on a mixed HDD/SSD cluster The tests verify: - Volume servers can be configured with specific disk types - ec.encode accepts -diskType flag and encodes to the correct disk type - ec.balance accepts -diskType flag and balances on the correct disk type - Mixed disk type clusters work correctly with separate collections --- test/erasure_coding/ec_integration_test.go | 541 +++++++++++++++++++++ 1 file changed, 541 insertions(+) diff --git a/test/erasure_coding/ec_integration_test.go b/test/erasure_coding/ec_integration_test.go index 67f8eed04..a1c73e706 100644 --- a/test/erasure_coding/ec_integration_test.go +++ b/test/erasure_coding/ec_integration_test.go @@ -1082,3 +1082,544 @@ func calculateDiskShardVariance(distribution map[string]map[int]int) float64 { return math.Sqrt(variance / float64(len(counts))) } + +// TestECDiskTypeSupport tests EC operations with different disk types (HDD, SSD) +// This verifies the -diskType flag works correctly for ec.encode and ec.balance +func TestECDiskTypeSupport(t *testing.T) { + if testing.Short() { + t.Skip("Skipping disk type integration test in short mode") + } + + testDir, err := os.MkdirTemp("", "seaweedfs_ec_disktype_test_") + require.NoError(t, err) + defer os.RemoveAll(testDir) + + ctx, cancel := context.WithTimeout(context.Background(), 180*time.Second) + defer cancel() + + // Start cluster with SSD disks + cluster, err := startClusterWithDiskType(ctx, testDir, "ssd") + require.NoError(t, err) + defer cluster.Stop() + + // Wait for servers to be ready + require.NoError(t, waitForServer("127.0.0.1:9335", 30*time.Second)) + for i := 0;
