Admin: misc improvements on admin server and workers. EC now works. (#7055)

* initial design * added simulation as tests * reorganized the codebase to move the simulation framework and tests into their own dedicated package * integration test. ec worker task * remove "enhanced" reference * start master, volume servers, filer Current Status ✅ Master: Healthy and running (port 9333) ✅ Filer: Healthy and running (port 8888) ✅ Volume Servers: All 6 servers running (ports 8080-8085) 🔄 Admin/Workers: Will start when dependencies are ready * generate write load * tasks are assigned * admin start wtih grpc port. worker has its own working directory * Update .gitignore * working worker and admin. Task detection is not working yet. * compiles, detection uses volumeSizeLimitMB from master * compiles * worker retries connecting to admin * build and restart * rendering pending tasks * skip task ID column * sticky worker id * test canScheduleTaskNow * worker reconnect to admin * clean up logs * worker register itself first * worker can run ec work and report status but: 1. one volume should not be repeatedly worked on. 2. ec shards needs to be distributed and source data should be deleted. * move ec task logic * listing ec shards * local copy, ec.

+# SeaweedFS EC Worker Testing Environment
+
+This Docker Compose setup provides a comprehensive testing environment for SeaweedFS Erasure Coding (EC) workers using **official SeaweedFS commands**.
+
+## 📂 Directory Structure
+
+The testing environment is located in `docker/admin_integration/` and includes:
+
+```
+docker/admin_integration/
+├── Makefile                     # Main management interface
+├── docker-compose-ec-test.yml   # Docker compose configuration
+├── EC-TESTING-README.md         # This documentation
+└── run-ec-test.sh              # Quick start script
+```
+
+## 🏗️ Architecture
+
+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  
+- **1 Filer** (port 8888) - Provides file system interface
+- **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
+
+## 🚀 Quick Start
+
+### Prerequisites
+
+- Docker and Docker Compose installed
+- GNU Make installed
+- At least 4GB RAM available for containers
+- Ports 8080-8085, 8888, 9333, 23646 available
+
+### Start the Environment
+
+```bash
+# Navigate to the admin integration directory
+cd docker/admin_integration/
+
+# Show available commands
+make help
+
+# Start the complete testing environment
+make start
+```
+
+The `make start` command will:
+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
+
+### Alternative Commands
+
+```bash
+# Quick start aliases
+make up              # Same as 'make start'
+
+# Development mode (higher load for faster testing)
+make dev-start
+
+# Build images without starting
+make build
+```

+
+## 🔄 How EC Testing Works
+
+### 1. Continuous Load Generation
+- **Write Rate**: 10 files/second (1-5MB each)
+- **Delete Rate**: 2 files/second
+- **Target**: Fill volumes to 50MB limit quickly
+
+### 2. Volume Detection
+- Admin server scans master every 30 seconds
+- Identifies volumes >40MB (80% of 50MB limit)
+- Queues EC tasks for eligible volumes
+
+### 3. EC Worker Assignment
+- **Worker 1**: EC specialist (max 2 concurrent tasks)
+- **Worker 2**: EC + Vacuum hybrid (max 2 concurrent tasks)  
+- **Worker 3**: EC + Vacuum hybrid (max 1 concurrent task)
+
+### 4. Comprehensive EC Process
+Each EC task follows 6 phases:
+1. **Copy Volume Data** (5-15%) - Stream .dat/.idx files locally
+2. **Mark Read-Only** (20-25%) - Ensure data consistency
+3. **Local Encoding** (30-60%) - Create 14 shards (10+4 Reed-Solomon)
+4. **Calculate Placement** (65-70%) - Smart rack-aware distribution
+5. **Distribute Shards** (75-90%) - Upload to optimal servers
+6. **Verify & Cleanup** (95-100%) - Validate and clean temporary files
+
+### 5. Real-Time Monitoring
+- Volume analysis and EC candidate detection
+- Worker health and task progress
+- No data loss verification
+- Performance metrics
+

+
+## 🛠️ Common Usage Patterns
+
+### Basic Testing Workflow
+```bash
+# Start environment
+make start
+
+# Watch progress
+make monitor-status
+
+# Check for EC candidates
+make volume-status
+
+# View worker activity
+make logs-workers
+
+# Stop when done
+make stop
+```
+
+### High-Load Testing
+```bash
+# Start with higher load
+make dev-start
+
+# Scale up workers and load
+make scale-workers WORKERS=5
+make scale-load RATE=50
+
+# Monitor intensive EC activity
+make logs-admin
+```
+
+### Debugging Issues
+```bash
+# Check port conflicts and system state
+make troubleshoot
+
+# View specific service logs
+make logs-admin
+make logs-worker1
+
+# Get shell access for debugging
+make shell-admin
+make shell-worker1
+
+# Check detailed status
+make debug
+```
+
+### Development Iteration
+```bash
+# Quick restart after code changes
+make restart
+
+# Rebuild and restart
+make clean
+make start
+
+# Monitor specific components
+make logs-monitor
+```
+
+## 📈 Expected Results
+
+### Successful EC Testing Shows:
+1. **Volume Growth**: Steady increase in volume sizes toward 50MB limit
+2. **EC Detection**: Admin server identifies volumes >40MB for EC
+3. **Task Assignment**: Workers receive and execute EC tasks
+4. **Shard Distribution**: 14 shards distributed across 6 volume servers
+5. **No Data Loss**: All files remain accessible during and after EC
+6. **Performance**: EC tasks complete within estimated timeframes
+
+### Sample Monitor Output:
+```bash
+# Check current status
+make monitor-status
+
+# Output example:
+{
+  "monitor": {
+    "uptime": "15m30s",
+    "master_addr": "master:9333",
+    "admin_addr": "admin:9900"
+  },
+  "stats": {
+    "VolumeCount": 12,
+    "ECTasksDetected": 3,
+    "WorkersActive": 3
+  }
+}
+```
+
+## 🔧 Configuration
+
+### Environment Variables
+
+You can customize the environment by setting variables:
+
+```bash
+# High load testing
+WRITE_RATE=25 DELETE_RATE=5 make start
+
+# Extended test duration
+TEST_DURATION=7200 make start  # 2 hours
+```
+
+### Scaling Examples
+
+```bash
+# Scale workers
+make scale-workers WORKERS=6
+
+# Increase load generation
+make scale-load RATE=30
+
+# Combined scaling
+make scale-workers WORKERS=4
+make scale-load RATE=40
+```
+
+## 🧹 Cleanup Options
+
+```bash
+# Stop services only
+make stop
+
+# Remove containers but keep volumes
+make down
+
+# Remove data volumes only
+make clean-volumes
+
+# Remove built images only
+make clean-images
+
+# Complete cleanup (everything)
+make clean
+```
+
+## 🐛 Troubleshooting
+
+### Quick Diagnostics
+```bash
+# Run complete troubleshooting
+make troubleshoot
+
+# Check specific components
+make health
+make debug
+make status
+```
+
+### Common Issues
+
+**Services not starting:**
+```bash
+# Check port availability
+make troubleshoot
+
+# View startup logs
+make logs-master
+make logs-admin
+```
+
+**No EC tasks being created:**
+```bash
+# Check volume status
+make volume-status
+
+# Increase load to fill volumes faster
+make scale-load RATE=30
+
+# Check admin detection
+make logs-admin
+```
+
+**Workers not responding:**
+```bash
+# Check worker registration
+make admin-status
+
+# View worker logs
+make logs-workers
+
+# Restart workers
+make restart
+```
+
+### Performance Tuning
+
+**For faster testing:**
+```bash
+make dev-start           # Higher default load
+make scale-load RATE=50  # Very high load
+```
+
+**For stress testing:**
+```bash
+make scale-workers WORKERS=8
+make scale-load RATE=100
+```
