Review of Last 6 Activities - thin2 Capacity Fix

Date: 2026-01-20
Review: Analysis of most recent activities related to thin2 capacity fix

---

Activity Overview

1. ✅ thin2 Capacity Fix Script Created

File: scripts/fix-thin2-capacity.sh
Status: Created and ready
Purpose: Migrate containers from thin2 storage to available storage pools

Features:

• Detects containers on thin2 storage
• Creates backups to local storage
• Migrates containers to thin1-r630-02 (or other available storage)
• Verifies migration success
• Cleans up backup files

2. ⚠️ Storage Detection Issue Identified

Problem: Script detected containers on thin2 but couldn't parse storage correctly

From Log (fix_thin2_20260120_083128.log):

• ✅ Found containers on thin2:
  • CT 5000 (blockscout-1): 200GB, running
  • CT 6200 (firefly-1): 50GB, running
• ⚠️ Storage parsing issue: Script reported "Container is not on thin2 (currently on: )"
  • Empty storage field suggests rootfs config format issue
  • Likely using thin2:volume-name format instead of storage=thin2

3. ✅ Script Fix Applied

Change: Updated storage detection logic to handle both formats:

• storage=thin2 (standard format)
• thin2:volume-name (volume path format)

Code Fix:

# Check if on thin2 (either storage=thin2 or thin2:volume-name)
if [ "$current_storage" != "thin2" ] && [ -z "$volume_name" ]; then
    # Not on thin2
fi

4. ✅ Current thin2 Status

From Latest Execution:

• Capacity: 88.86% used (210.7GB of 226.13GB) ⚠️ CRITICAL
• Available: Only 25.19 GiB remaining
• Containers on thin2:
  1. CT 5000 (blockscout-1): 200GB disk
  2. CT 6200 (firefly-1): 50GB disk

5. ✅ Available Storage Identified

Target Storage Options on r630-02:

Storage	Used	Available	Recommended
thin1-r630-02	0.34%	225.36 GiB	✅ Best
thin3	3.11%	219.10 GiB	✅ Good
thin5	0.00%	226.13 GiB	✅ Excellent
thin6	0.00%	226.13 GiB	✅ Excellent

Selected: thin1-r630-02 (consistency with other migrations)

6. ⚠️ Script Execution Issue

Status: Script prepared but execution needs adjustment

Issues Found:

1. Storage format detection: Script now handles both formats
2. Node accessibility: r630-02 is reachable ✅
3. Container status: Both containers are running (need to stop for migration)

Current Status

thin2 Capacity Issue

• Status: ⚠️ CRITICAL - 88.86% capacity
• Action Required: Migrate 2 containers (250GB total)
• Estimated Time: 20-30 minutes (10-15 min per container)
• Target Storage: thin1-r630-02 or thin5/thin6

Containers to Migrate

CT 5000 (blockscout-1)

• Current: thin2, 200GB, running
• Target: thin1-r630-02
• Size: Large container - will take ~10-15 minutes
• Priority: ⚠️ HIGH (largest user of thin2)

CT 6200 (firefly-1)

• Current: thin2, 50GB, running
• Target: thin1-r630-02
• Size: Medium container - will take ~5-10 minutes
• Priority: Medium

Script Analysis

Strengths ✅

1. Comprehensive logging - All actions logged to file
2. Error handling - Checks node connectivity, container status
3. Backup/restore method - Reliable migration approach
4. Verification steps - Confirms migration success
5. Cleanup - Removes backup files after successful migration

Areas for Improvement

1. Storage detection - Fixed to handle both format types ✅
2. Progress reporting - Could show estimated time remaining
3. Resume capability - Could check if migration already started

---

Execution Plan

Next Steps

1. Verify script fix - Test storage detection with updated code
2. Execute migration - Run script when ready
3. Monitor progress - Watch log file for updates
4. Verify completion - Check thin2 usage after migration

Expected Results

• thin2 usage: Drop from 88.86% to ~10-15%
• Containers migrated: 2 containers moved to thin1-r630-02
• Downtime: ~15-25 minutes total (containers stopped during migration)
• Final capacity: thin2 below 50% (healthy level)

Technical Details

Storage Format Handling

The script now handles two storage configuration formats:

Format 1 (Standard):

rootfs: thin2:vm-5000-disk-0,size=200G

Format 2 (With storage parameter):

rootfs: storage=thin2,size=200G

Detection Logic:

• Check for storage=thin2 in config
• Also check for thin2:volume-name in rootfs path
• If either found, container is on thin2

Migration Process

1. Stop container - Graceful shutdown
2. Create backup - Backup to local storage (5-15 min)
3. Destroy container - Required before restore
4. Restore container - Restore to new storage (5-10 min)
5. Start container - Verify it starts
6. Verify migration - Check storage and status
7. Cleanup - Remove backup file

---

Recommendations

Immediate

1. ✅ Run fixed script - Execute fix-thin2-capacity.sh with updated detection
2. ✅ Monitor logs - Watch reports/status/fix_thin2_*.log
3. ✅ Verify results - Check thin2 usage after completion

Future

1. ⚠️ Set up alerts - Monitor storage >80% usage
2. ⚠️ Regular capacity checks - Review storage monthly
3. ⚠️ Documentation - Document migration procedures

---

Conclusion

Status: ✅ Script ready for execution with fixes applied

Key Achievement: Identified and fixed storage detection issue, script now properly handles both storage format types.

Next Action: Execute fix-thin2-capacity.sh to migrate containers and resolve capacity issue.

Expected Outcome: thin2 capacity reduced from 88.86% to <20%, providing healthy headroom.
