 # SeaweedFS EC Worker Testing Environment

 ## 🏗️ Architecture

-The testing environment includes:
+The testing environment uses **official SeaweedFS commands** and includes:

 - **1 Master Server** (port 9333) - Coordinates the cluster with 50MB volume size limit
- **6 Volume Servers** (ports 8080-8085) - Distributed across 2 data centers and 3 racks for diversity
+- **6 Volume Servers** (ports 8080-8085) - Distributed across 2 data centers and 3 racks for diversity  
 - **1 Filer** (port 8888) - Provides file system interface
- **1 Admin Server** (port 9900) - Detects volumes needing EC and manages workers
- **3 EC Workers** - Execute erasure coding tasks with different capabilities
- **1 Load Generator** - Continuously writes and deletes files to trigger EC
- **1 Monitor** (port 9999) - Tracks cluster health and EC progress
+- **1 Admin Server** (port 23646) - Detects volumes needing EC and manages workers using official `admin` command
+- **3 EC Workers** - Execute erasure coding tasks using official `worker` command with task-specific working directories
+- **1 Load Generator** - Continuously writes and deletes files using SeaweedFS shell commands
+- **1 Monitor** - Tracks cluster health and EC progress using shell scripts
+
+## ✨ New Features
+
+### **Task-Specific Working Directories**
+Each worker now creates dedicated subdirectories for different task types:
+- `/work/erasure_coding/` - For EC encoding tasks
+- `/work/vacuum/` - For vacuum cleanup tasks  
+- `/work/balance/` - For volume balancing tasks
+
+This provides:
+- **Organization**: Each task type gets isolated working space
+- **Debugging**: Easy to find files/logs related to specific task types
+- **Cleanup**: Can clean up task-specific artifacts easily
+- **Concurrent Safety**: Different task types won't interfere with each other's files

 ```

 The `make start` command will:
-1. Build all necessary Docker images
-2. Start all services in the correct order
+1. Start all services using official SeaweedFS images
+2. Configure workers with task-specific working directories
 3. Wait for services to be ready
 4. Display monitoring URLs and run health checks
