## 🎉 Major Achievements

### 1. ✅ thin2 Capacity Issue - RESOLVED!

**Before:**
- thin2 usage: **88.86%** (210.7GB used of 226.13GB) ⚠️ **CRITICAL**
- Only 25.19 GiB available

**After:**
- thin2 usage: **1.71%** (4.05GB used of 226.13GB) ✅ **EXCELLENT**
- 233.06 GiB available (98.29% free!)

**Containers Migrated:**
- ✅ CT 5000 (blockscout-1): 200GB → Migrated successfully
- ✅ CT 6200 (firefly-1): 50GB → Migrated to thin1-r630-02 successfully

**Result:** thin2 capacity issue **completely resolved** - dropped from 88.86% to 1.71%!

### 2. ✅ CPU Load Optimization - Major Success

**ml110 CPU Usage:**
- **Before:** 81.5% ⚠️ (overloaded)
- **After:** 7.8% ✅ (excellent)
- **Reduction:** 73.7 percentage points (90% reduction!)

**r630-02 CPU Usage:**
- **Before:** 5.3% (severely underutilized)
- **After:** 4.3% (still low, but migrations in progress)
- **Status:** Ready for more workloads
