Ceph Storage Cluster Testing Strategy QA Health Check Performance Benchmark Failure Injection Recovery Verification CRUSH OSD MON RBD RGW CephFS Production
| Storage Type | Interface | Use Case | Test Tool | Key Metric |
|---|---|---|---|---|
| RBD (Block) | Block Device | VM Disk K8s PV | fio rbd bench | IOPS Latency |
| RGW (Object) | S3 / Swift API | Backup Media | cosbench s3cmd | Throughput |
| CephFS (File) | POSIX Mount | Shared Files | fio iozone | IOPS Throughput |
| RADOS (Raw) | librados | Internal | rados bench | Throughput Latency |
เคล็ดลับ
- Baseline: วัด Performance Baseline ก่อนทุก Change
- Scrub: Deep Scrub ตรวจ Data Integrity หลังทุก Failure Test
- Staging: ทดสอบ Failure ใน Staging ก่อน Production เสมอ
- Monitor: ดู ceph -s ตลอดระหว่างทดสอบ
- Runbook: สร้าง Runbook สำหรับทุก Failure Scenario
