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. Need to distribute.

* ec is mostly working now

* distribution of ec shards needs improvement
* need configuration to enable ec

* show ec volumes

* interval field UI component

* rename

* integration test with vauuming

* garbage percentage threshold

* fix warning

* display ec shard sizes

* fix ec volumes list

* use volumeSizeLimitMB

* remove

remove

* remove unused

* refactor

* use new framework

* remove v2 reference

🎯 Planning: ActiveTopology creates DestinationPlan with specific TargetDisk
📦 Task Creation: maintenance_integration.go creates ECDestination with DiskId
🚀 Task Execution: EC task passes DiskId in VolumeEcShardsCopyRequest
💾 Volume Server: Receives disk_id and stores shards on specific disk (vs.store.Locations[req.DiskId])
📂 File System: EC shards and metadata land in the exact disk directory planned

* Delete original volume from all locations

* clean up existing shard locations

* local encoding and distributing

* Update docker/admin_integration/EC-TESTING-README.md

+```
+
+## 1. Admin Server Design
+
+### 1.1 Core Responsibilities
+
+- **Task Discovery**: Scan volumes to identify EC and vacuum candidates
+- **Worker Management**: Track available workers and their capabilities  
+- **Task Assignment**: Match tasks to optimal workers
+- **Progress Tracking**: Monitor in-progress tasks for capacity planning
+- **State Reconciliation**: Sync with master server for volume state updates
+
+### 1.2 Task Discovery Engine
+
+```go
+type TaskDiscoveryEngine struct {
+    masterClient   MasterClient
+    volumeScanner  VolumeScanner
+    taskDetectors  map[TaskType]TaskDetector
+    scanInterval   time.Duration
+}
+
+type VolumeCandidate struct {
+    VolumeID       uint32
+    Server         string
+    Collection     string
+    TaskType       TaskType
+    Priority       TaskPriority
+    Reason         string
+    DetectedAt     time.Time
+    Parameters     map[string]interface{}
+}
+```
+
+**EC Detection Logic**:
+- Find volumes >= 95% full and idle for > 1 hour
+- Exclude volumes already in EC format
+- Exclude volumes with ongoing operations
+- Prioritize by collection and age
+
+**Vacuum Detection Logic**:
+- Find volumes with garbage ratio > 30%
+- Exclude read-only volumes
+- Exclude volumes with recent vacuum operations
+- Prioritize by garbage percentage
+
+### 1.3 Worker Registry & Management
+
+```go
+type WorkerRegistry struct {
+    workers        map[string]*Worker
+    capabilities   map[TaskType][]*Worker
+    lastHeartbeat  map[string]time.Time
+    taskAssignment map[string]*Task
+    mutex          sync.RWMutex
+}
+
+type Worker struct {
+    ID            string
+    Address       string
+    Capabilities  []TaskType
+    MaxConcurrent int
+    CurrentLoad   int
+    Status        WorkerStatus
+    LastSeen      time.Time
+    Performance   WorkerMetrics
+}
+```
+
+### 1.4 Task Assignment Algorithm
+
+```go
+type TaskScheduler struct {
+    registry       *WorkerRegistry
+    taskQueue      *PriorityQueue
+    inProgressTasks map[string]*InProgressTask
+    volumeReservations map[uint32]*VolumeReservation
+}
+
+// Worker Selection Criteria:
+// 1. Has required capability (EC or Vacuum)
+// 2. Available capacity (CurrentLoad < MaxConcurrent)
+// 3. Best performance history for task type
+// 4. Lowest current load
+// 5. Geographically close to volume server (optional)
+```
+
+## 2. Worker Process Design
+
+### 2.1 Worker Architecture
+
+```go
+type MaintenanceWorker struct {
+    id              string
+    config          *WorkerConfig
+    adminClient     AdminClient
+    taskExecutors   map[TaskType]TaskExecutor
+    currentTasks    map[string]*RunningTask
+    registry        *TaskRegistry
+    heartbeatTicker *time.Ticker
+    requestTicker   *time.Ticker
+}
+```
+
+### 2.2 Task Execution Framework
+
+```go
+type TaskExecutor interface {
+    Execute(ctx context.Context, task *Task) error
+    EstimateTime(task *Task) time.Duration
+    ValidateResources(task *Task) error
+    GetProgress() float64
+    Cancel() error
+}
+
+type ErasureCodingExecutor struct {
+    volumeClient VolumeServerClient
+    progress     float64
+    cancelled    bool
+}
+
+type VacuumExecutor struct {
+    volumeClient VolumeServerClient
+    progress     float64
+    cancelled    bool
+}
+```
+
+### 2.3 Worker Capabilities & Registration
+
+```go
+type WorkerCapabilities struct {
+    SupportedTasks   []TaskType
+    MaxConcurrent    int
+    ResourceLimits   ResourceLimits
+    PreferredServers []string  // Affinity for specific volume servers
+}
+
+type ResourceLimits struct {
+    MaxMemoryMB      int64
+    MaxDiskSpaceMB   int64
+    MaxNetworkMbps   int64
+    MaxCPUPercent    float64
+}
+```
+
+## 3. Task Lifecycle Management
+
+### 3.1 Task States
+
+```go
+type TaskState string
+
+const (
+    TaskStatePending     TaskState = "pending"
+    TaskStateAssigned    TaskState = "assigned"
+    TaskStateInProgress  TaskState = "in_progress"
+    TaskStateCompleted   TaskState = "completed"
+    TaskStateFailed      TaskState = "failed"
+    TaskStateCancelled   TaskState = "cancelled"
+    TaskStateStuck       TaskState = "stuck"       // Taking too long
+    TaskStateDuplicate   TaskState = "duplicate"   // Detected duplicate
+)
+```
+
+### 3.2 Progress Tracking & Monitoring
+
+```go
+type InProgressTask struct {
+    Task           *Task
+    WorkerID       string
+    StartedAt      time.Time
+    LastUpdate     time.Time
+    Progress       float64
+    EstimatedEnd   time.Time
+    VolumeReserved bool  // Reserved for capacity planning
+}
+
+type TaskMonitor struct {
+    inProgressTasks map[string]*InProgressTask
+    timeoutChecker  *time.Ticker
+    stuckDetector   *time.Ticker
+    duplicateChecker *time.Ticker
+}
+```
+
+## 4. Volume Capacity Reconciliation
+
+### 4.1 Volume State Tracking
+
+```go
+type VolumeStateManager struct {
+    masterClient      MasterClient
+    inProgressTasks   map[uint32]*InProgressTask  // VolumeID -> Task
+    committedChanges  map[uint32]*VolumeChange    // Changes not yet in master
+    reconcileInterval time.Duration
+}
+
+type VolumeChange struct {
+    VolumeID     uint32
+    ChangeType   ChangeType  // "ec_encoding", "vacuum_completed"
+    OldCapacity  int64
+    NewCapacity  int64
+    TaskID       string
+    CompletedAt  time.Time
+    ReportedToMaster bool
+}
+```
+
+### 4.2 Shard Assignment Integration
+
+When the master needs to assign shards, it must consider:
+1. **Current volume state** from its own records
+2. **In-progress capacity changes** from admin server
+3. **Committed but unreported changes** from admin server
+
+```go
+type CapacityOracle struct {
+    adminServer   AdminServerClient
+    masterState   *MasterVolumeState
+    updateFreq    time.Duration
+}
+
+func (o *CapacityOracle) GetAdjustedCapacity(volumeID uint32) int64 {
+    baseCapacity := o.masterState.GetCapacity(volumeID)
+    
+    // Adjust for in-progress tasks
+    if task := o.adminServer.GetInProgressTask(volumeID); task != nil {
+        switch task.Type {
+        case TaskTypeErasureCoding:
+            // EC reduces effective capacity
+            return baseCapacity / 2  // Simplified
+        case TaskTypeVacuum:
+            // Vacuum may increase available space
+            return baseCapacity + int64(float64(baseCapacity) * 0.3)
+        }
+    }
+    
+    // Adjust for completed but unreported changes
+    if change := o.adminServer.GetPendingChange(volumeID); change != nil {
+        return change.NewCapacity
+    }
+    
+    return baseCapacity
+}
+```
+
+## 5. Error Handling & Recovery
+
+### 5.1 Worker Failure Scenarios
+
+```go
+type FailureHandler struct {
+    taskRescheduler *TaskRescheduler
+    workerMonitor   *WorkerMonitor
+    alertManager    *AlertManager
+}
+
+// Failure Scenarios:
+// 1. Worker becomes unresponsive (heartbeat timeout)
+// 2. Task execution fails (reported by worker)
+// 3. Task gets stuck (progress timeout)
+// 4. Duplicate task detection
+// 5. Resource exhaustion
+```
+
+### 5.2 Recovery Strategies
+
+**Worker Timeout Recovery**:
+- Mark worker as inactive after 3 missed heartbeats
+- Reschedule all assigned tasks to other workers
+- Cleanup any partial state
+
+**Task Stuck Recovery**:
+- Detect tasks with no progress for > 2x estimated time
+- Cancel stuck task and mark volume for cleanup
+- Reschedule if retry count < max_retries
+
+**Duplicate Task Prevention**:
+```go
+type DuplicateDetector struct {
+    activeFingerprints map[string]bool  // VolumeID+TaskType
+    recentCompleted    *LRUCache        // Recently completed tasks
+}
+
+func (d *DuplicateDetector) IsTaskDuplicate(task *Task) bool {
+    fingerprint := fmt.Sprintf("%d-%s", task.VolumeID, task.Type)
+    return d.activeFingerprints[fingerprint] || 
+           d.recentCompleted.Contains(fingerprint)
+}
+```
+
+## 6. Simulation & Testing Framework
+
+### 6.1 Failure Simulation
+
+```go
+type TaskSimulator struct {
+    scenarios map[string]SimulationScenario
+}
+
+type SimulationScenario struct {
+    Name            string
+    WorkerCount     int
+    VolumeCount     int
+    FailurePatterns []FailurePattern
+    Duration        time.Duration
+}
+
+type FailurePattern struct {
+    Type        FailureType  // "worker_timeout", "task_stuck", "duplicate"
+    Probability float64      // 0.0 to 1.0
+    Timing      TimingSpec   // When during task execution
+    Duration    time.Duration
+}
+```
+
+### 6.2 Test Scenarios
+
+**Scenario 1: Worker Timeout During EC**
+- Start EC task on 30GB volume
+- Kill worker at 50% progress
+- Verify task reassignment
+- Verify no duplicate EC operations
+
+**Scenario 2: Stuck Vacuum Task**
+- Start vacuum on high-garbage volume
+- Simulate worker hanging at 75% progress
+- Verify timeout detection and cleanup
+- Verify volume state consistency
+
+**Scenario 3: Duplicate Task Prevention**
+- Submit same EC task from multiple sources
+- Verify only one task executes
+- Verify proper conflict resolution
+
+**Scenario 4: Master-Admin State Divergence**
+- Create in-progress EC task
+- Simulate master restart
+- Verify state reconciliation
+- Verify shard assignment accounts for in-progress work
+
+## 7. Performance & Scalability
+
+### 7.1 Metrics & Monitoring
+
+```go
+type SystemMetrics struct {
+    TasksPerSecond     float64
+    WorkerUtilization  float64
+    AverageTaskTime    time.Duration
+    FailureRate        float64
+    QueueDepth         int
+    VolumeStatesSync   bool
+}
+```
+
+### 7.2 Scalability Considerations
+
+- **Horizontal Worker Scaling**: Add workers without admin server changes
+- **Admin Server HA**: Master-slave admin servers for fault tolerance
+- **Task Partitioning**: Partition tasks by collection or datacenter
+- **Batch Operations**: Group similar tasks for efficiency
+
+## 8. Implementation Plan
+
+### Phase 1: Core Infrastructure
+1. Admin server basic framework
+2. Worker registration and heartbeat
+3. Simple task assignment
+4. Basic progress tracking
+
+### Phase 2: Advanced Features
+1. Volume state reconciliation
+2. Sophisticated worker selection
+3. Failure detection and recovery
+4. Duplicate prevention
+
+### Phase 3: Optimization & Monitoring
+1. Performance metrics
+2. Load balancing algorithms
+3. Capacity planning integration
+4. Comprehensive monitoring
+
+This design provides a robust, scalable foundation for distributed task management in SeaweedFS while maintaining consistency with the existing architecture patterns.

+# 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

+## 🔄 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
+```
