## Storage Mapping & Usage Patterns
|
||||
|
||||
### Shared NFS Mounts
|
||||
|
||||
```
|
||||
All Nodes can access:
|
||||
├── dlx-nfs-sdb-02 → Backup/images (3.9 TB) - 0.07% used
|
||||
├── dlx-nfs-sdc-00 → Images/rootdir (1.9 TB) - 7.47% used
|
||||
├── dlx-nfs-sdd-00 → Templates/ISO/backup (1.9 TB) - 0.63% used
|
||||
└── dlx-nfs-sde-00 → Templates/ISO/images (1.9 TB) - 2.83% used
|
||||
```
|
||||
|
||||
### Node-Specific Storage
|
||||
|
||||
```
|
||||
proxmox-00 (Control Hub):
|
||||
├── local (62 GB) ⚠️ CRITICAL: 84.5% FULL
|
||||
├── dlx-sda (1.9 TB) - 3.3% used
|
||||
├── dlx-sdb ZFS (1.9 TB) - 0.2% used
|
||||
├── dlx-sdf4 LVM (785 GB) - 20.5% used
|
||||
└── local-lvm (116 GB) - 0% used
|
||||
|
||||
proxmox-01 (Docker/Services):
|
||||
├── local (62 GB) - 69.5% used
|
||||
├── dlx-docker (718 GB) ⚠️ HIGH: 81.1% USED
|
||||
└── local-lvm (116 GB) - 0% used
|
||||
|
||||
proxmox-02 (Development):
|
||||
├── local (92 GB) - 47.2% used
|
||||
├── dlx-data (702 GB) - 9.1% used (NVME, fast)
|
||||
└── local-lvm (160 GB) - 0% used
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Capacity & Utilization Summary
|
||||
|
||||
| Metric | Value | Status |
|
||||
|--------|-------|--------|
|
||||
| **Total Capacity** | ~17 TB | ✓ Adequate |
|
||||
| **Total Used** | ~1.3 TB | ✓ 7.6% |
|
||||
| **Total Available** | ~15.7 TB | ✓ Healthy |
|
||||
| **Shared NFS** | 9.7 TB (2.2% used) | ✓ Excellent |
|
||||
| **Local Storage** | 7.3 TB (18.3% used) | ⚠️ Mixed |
|
||||
|
||||

|
||||
|
||||
## Critical Issues & Recommendations
|
||||
|
||||
### 🔴 CRITICAL: proxmox-00 Root Filesystem
|
||||
|
||||
**Issue**: `/` (root) is 84.5% full (52.6 GB of 62 GB)
|
||||
|
||||
**Impact**:
|
||||
- System may become unstable
|
||||
- Package installation may fail
|
||||
- Logs may stop being written
|
||||
|
||||
**Recommendation**:
|
||||
1. Clean up old logs: `journalctl --vacuum=time:30d`
|
||||
2. Check for old snapshots/backups
|
||||
3. Consider moving `/var` to separate storage
|
||||
4. Monitor closely for growth
|
||||
|
||||
---
|
||||
|
||||
### 🟠 HIGH PRIORITY: proxmox-01 dlx-docker
|
||||
|
||||
**Issue**: dlx-docker storage at 81.1% capacity (568 GB of 718 GB)
|
||||
|
||||
**Impact**:
|
||||
- Limited room for container growth
|
||||
- Risk of running out of space during operations
|
||||
|
||||
**Recommendation**:
|
||||
1. Audit running containers: `docker ps -a --format "{{.Names}}: {{json .SizeRw}}"`
|
||||
2. Remove unused images/layers
|
||||
3. Consider expanding partition or migrating data
|
||||
4. Set up monitoring for capacity
|
||||
|
||||
---
|
||||
|
||||
### 🟠 HIGH PRIORITY: proxmox-01 dlx-sonar
|
||||
|
||||
**Issue**: SonarQube using 354 GB (82% of allocated 422 GB)
|
||||
|
||||
**Impact**:
|
||||
- Large analysis database
|
||||
- May need separate storage strategy
|
||||
|
||||
**Recommendation**:
|
||||
1. Review SonarQube retention policies
|
||||
2. Archive old analysis data
|
||||
3. Consider separate backup strategy
|
||||
|
||||
---
|
||||
|
||||
### ⚠️ Medium Priority: Storage Inconsistency
|
||||
|
||||
**Issue**: Disabled storage backends across nodes
|
||||
|
||||
| Backend | disabled on | Notes |
|
||||
|---------|-------------|-------|
|
||||
| dlx-docker | proxmox-00, 02 | Only enabled on 01 |
|
||||
| dlx-data | proxmox-00, 01 | Only enabled on 02 |
|
||||
| dlx-sda | proxmox-01 | Enabled on 00 only |
|
||||
| dlx-sdb (ZFS) | proxmox-01, 02 | Only enabled on 00 |
|
||||
| dlx-sdf4 (LVM) | proxmox-01, 02 | Only enabled on 00 |
|
||||
|
||||
**Recommendation**:
|
||||
1. Document why each backend is disabled per node
|
||||
2. Standardize storage configuration across cluster
|
||||
3. Consider cluster-wide storage policy
|
||||
|
||||
---
|
||||
|
||||
### ⚠️ Medium Priority: Container Lifecycle
|
||||
|
||||
**Issue**: 15 containers are stopped but still allocating space (1.2 TB total)
|
||||
|
||||
**Recommendation**:
|
||||
1. Audit stopped containers (dlx-swarm-*, dlx-kube-*, etc.)
|
||||
2. Delete unused containers to reclaim space
|
||||
3. Document intended purpose of stopped containers
|
||||
|
||||
---
|
||||
|
||||
## Recommendations Summary
|
||||
|
||||
### Immediate (Next week)
|
||||
1. ✅ Compress logs on proxmox-00 root filesystem
|
||||
2. ✅ Audit dlx-docker usage and remove unused images
|
||||
3. ✅ Monitor proxmox-01 dlx-docker capacity
|
||||
|
||||
### Short-term (1-2 months)
|
||||
1. Expand dlx-docker partition or migrate high-usage containers
|
||||
2. Archive SonarQube data or increase disk allocation
|
||||
3. Clean up stopped containers or document their retention
|
||||
|
||||
### Long-term (3-6 months)
|
||||
1. Implement automated capacity monitoring
|
||||
2. Standardize storage backend configuration across cluster
|
||||
3. Establish storage lifecycle policies (snapshots, backups, retention)
|
||||
4. Consider tiered storage strategy (fast NVME vs. slow SATA)

|
||||
|
||||
## Execution Plan
|
||||
|
||||
### Phase 1: Preparation (Before running playbooks)
|
||||
|
||||
#### 1. Verify backups exist
|
||||
```bash
|
||||
# Check backup location
|
||||
ls -lh /var/backups/
|
||||
```
|
||||
|
||||
#### 2. Review current state
|
||||
```bash
|
||||
# Check filesystem usage
|
||||
df -h /
|
||||
df -h /mnt/pve/*
|
||||
|
||||
# Check Docker usage (proxmox-01 only)
|
||||
docker system df
|
||||
|
||||
# List containers
|
||||
pct list | head -20
|
||||
qm list | head -20
|
||||
```
|
||||
|
||||
#### 3. Document baseline
|
||||
```bash
|
||||
# Capture baseline metrics
|
||||
ansible proxmox -m shell -a "df -h /" -u dlxadmin > baseline-storage.txt
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 2: Execute Remediation
|
||||
|
||||
#### Step 1: Test with dry-run (RECOMMENDED)
|
||||
|
||||
```bash
|
||||
# Test critical issues fix
|
||||
ansible-playbook playbooks/remediate-storage-critical-issues.yml \
|
||||
--check -l proxmox-00
|
||||
|
||||
# Test Docker cleanup
|
||||
ansible-playbook playbooks/remediate-docker-storage.yml \
|
||||
--check -l proxmox-01
|
||||
|
||||
# Test container removal
|
||||
ansible-playbook playbooks/remediate-stopped-containers.yml \
|
||||
--check
|
||||
```
|
||||
|
||||
Review output before proceeding to Step 2.
|
||||
|
||||
#### Step 2: Execute on proxmox-00 (Critical)
|
||||
|
||||
```bash
|
||||
# Clean up root filesystem and logs
|
||||
ansible-playbook playbooks/remediate-storage-critical-issues.yml \
|
||||
-l proxmox-00 -v
|
||||
```
|
||||
|
||||
**Verification**:
|
||||
```bash
|
||||
# SSH to proxmox-00
|
||||
ssh dlxadmin@192.168.200.10
|
||||
df -h /
|
||||
# Should show: from 84.5% → 70-75%
|
||||
|
||||
du -sh /var/log
|
||||
# Should show: smaller size after cleanup
|
||||
```
|
||||
|
||||
#### Step 3: Execute on proxmox-01 (High Priority)
|
||||
|
||||
```bash
|
||||
# Clean Docker storage
|
||||
ansible-playbook playbooks/remediate-docker-storage.yml \
|
||||
-l proxmox-01 -v
|
||||
```
|
||||
|
||||
**Verification**:
|
||||
```bash
|
||||
# SSH to proxmox-01
|
||||
ssh dlxadmin@192.168.200.11
|
||||
df -h /mnt/pve/dlx-docker
|
||||
# Should show: from 81% → 60-70%
|
||||
|
||||
docker system df
|
||||
# Should show: reduced image/volume sizes
|
||||
```
|
||||
|
||||
#### Step 4: Remove Stopped Containers (Optional)
|
||||
|
||||
```bash
|
||||
# First, verify which containers will be removed
|
||||
ansible-playbook playbooks/remediate-stopped-containers.yml \
|
||||
--check
|
||||
|
||||
# Review output, then execute
|
||||
ansible-playbook playbooks/remediate-stopped-containers.yml \
|
||||
-e dry_run=false -v
|
||||
```
|
||||
|
||||
**Verification**:
|
||||
```bash
|
||||
# Check backup location
|
||||
ls -lh /tmp/pve-container-backups/
|
||||
|
||||
# Verify stopped containers are gone
|
||||
pct list | grep stopped
|
||||
```
|
||||
|
||||
#### Step 5: Enable Monitoring
|
||||
|
||||
```bash
|
||||
# Configure monitoring on all hosts
|
||||
ansible-playbook playbooks/configure-storage-monitoring.yml \
|
||||
-l proxmox
|
||||
```
|
||||
|
||||
**Verification**:
|
||||
```bash
|
||||
# Check monitoring scripts installed
|
||||
ls -la /usr/local/bin/storage-monitoring/
|
||||
|
||||
# Check cron jobs
|
||||
crontab -l | grep storage
|
||||
|
||||
# View monitoring logs
|
||||
tail -f /var/log/storage-monitor.log
|
||||
```

|
||||
## Rollback Plan
|
||||
|
||||
If something goes wrong, you can roll back:
|
||||
|
||||
### Restore Filesystem from Snapshot
|
||||
```bash
|
||||
# If you have LVM snapshots
|
||||
lvconvert --merge /dev/mapper/pve-root_snapshot
|
||||
|
||||
# Or restore from backup
|
||||
proxmox-backup-client restore /mnt/backups/...
|
||||
```
|
||||
|
||||
### Recover Deleted Containers
|
||||
```bash
|
||||
# Restore from backed-up config
|
||||
pct restore /tmp/pve-container-backups/container-108-dlx-mysql-02.conf 108
|
||||
|
||||
# Start container
|
||||
pct start 108
|
||||
```
|
||||
|
||||
### Restore Docker Images
|
||||
```bash
|
||||
# Pull images from registry
|
||||
docker pull image:tag
|
||||
|
||||
# Or restore from backup
|
||||
docker load < image-backup.tar
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Monitoring & Validation
|
||||
|
||||
### Daily Checks
|
||||
```bash
|
||||
# Monitor storage trends
|
||||
tail -f /var/log/storage-monitor.log
|
||||
|
||||
# Check cluster status
|
||||
/usr/local/bin/storage-monitoring/cluster-status.sh
|
||||
|
||||
# Alert check
|
||||
grep ALERT /var/log/storage-monitor.log
|
||||
```
|
||||
|
||||
### Weekly Verification
|
||||
```bash
|
||||
# Run storage audit
|
||||
ansible-playbook playbooks/remediate-storage-critical-issues.yml --check
|
||||
|
||||
# Review Docker logs
|
||||
docker system df
|
||||
|
||||
# List containers by size
|
||||
pct list | while read line; do
|
||||
vmid=$(echo $line | awk '{print $1}')
|
||||
name=$(echo $line | awk '{print $2}')
|
||||
size=$(du -sh /var/lib/lxc/$vmid 2>/dev/null | awk '{print $1}')
|
||||
echo "$vmid $name $size"
|
||||
done | sort -k3 -hr
|
||||
```
|
||||
|
||||
### Monthly Audit
|
||||
```bash
|
||||
# Update storage audit report
|
||||
ansible-playbook playbooks/remediate-storage-critical-issues.yml --check -v
|
||||
|
||||
# Generate updated metrics
|
||||
pvesh get /nodes/proxmox-00/storage | grep capacity
|
||||
|
||||
# Compare to baseline
|
||||
diff baseline-storage.txt <(ansible proxmox -m shell -a "df -h /" -u dlxadmin)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: Root filesystem still full after cleanup
|
||||
|
||||
**Symptoms**: `df -h /` still shows >80%
|
||||
|
||||
**Solutions**:
|
||||
1. Check for large files: `find / -size +1G 2>/dev/null`
|
||||
2. Check Docker: `docker system prune -a`
|
||||
3. Check logs: `du -sh /var/log/* | sort -hr | head`
|
||||
4. Expand partition (if necessary)
|
||||
|
||||
### Issue: Docker cleanup removed needed image
|
||||
|
||||
**Symptoms**: Container fails to start after cleanup
|
||||
|
||||
**Solution**: Rebuild or pull image
|
||||
```bash
|
||||
docker pull image:tag
|
||||
docker-compose up -d
|
||||
```
|
||||
|
||||
### Issue: Removed container was still in use
|
||||
|
||||
**Recovery**: Restore from backup
|
||||
```bash
|
||||
# List available backups
|
||||
ls -la /tmp/pve-container-backups/
|
||||
|
||||
# Restore to new VMID
|
||||
pct restore /tmp/pve-container-backups/container-108-dlx-mysql-02.conf 200
|
||||
pct start 200
|
||||
```

Playbooks Created:
|
||||
1. remediate-storage-critical-issues.yml
|
||||
- Cleans logs on proxmox-00
|
||||
- Prunes Docker on proxmox-01
|
||||
- Audits SonarQube usage
|
||||
|
||||
2. remediate-docker-storage.yml
|
||||
- Detailed Docker cleanup
|
||||
- Removes dangling resources
|
||||
- Sets up automated weekly prune
|
||||
|
||||
3. remediate-stopped-containers.yml
|
||||
- Safely removes unused containers
|
||||
- Creates config backups
|
||||
- Recoverable deletions
|
||||
|
||||
4. configure-storage-monitoring.yml
|
||||
- Continuous capacity monitoring
|
||||
- Alert thresholds (75/85/95%)
|
||||
- Prometheus integration
|
||||
|
||||
To Execute All Remediations:
|
||||
$ ansible-playbook playbooks/remediate-storage-critical-issues.yml
|
||||
$ ansible-playbook playbooks/remediate-docker-storage.yml
|
||||
$ ansible-playbook playbooks/configure-storage-monitoring.yml
|

$ /usr/local/bin/storage-monitoring/cluster-status.sh
|
||||
|
||||
Next Steps:
|
||||
1. Review and test playbooks with --check
|
||||
2. Run on one host first (proxmox-00)
|

|
||||
- proxmox-00 root: 84.5% → 70%
|
||||
- proxmox-01 docker: 81.1% → 70%
|
||||
- Freed space: 500+ GB

⚠️ SAFETY CHECK - DO NOT PROCEED WITHOUT VERIFICATION:
|

|

1. VERIFY BACKUPS:
|
||||
ls -lh {{ backup_dir }}/
|
||||
Should show .conf and .status files for all containers
|
||||
|
||||
2. CHECK DEPENDENCIES:
|
||||
- Is dlx-mysql-01 running and taking load?
|
||||
- Are swarm/kube services actually needed?
|
||||
- Is wireguard currently in use?
|
||||
|
||||
3. DATABASE VERIFICATION:
|
||||
If removing MySQL replicas:
|
||||
- Check that dlx-mysql-01 is healthy
|
||||
- Verify replication is not in progress
|
||||
- Confirm no active connections from replicas
|
||||
|
||||
4. FINAL CONFIRMATION:
|
||||
Review each container's last modification time

✓ COMPLETED ACTIONS:
|
||||
1. Compressed journal logs on proxmox-00
|
||||
2. Cleaned old syslog files (>90 days)
|
||||
3. Cleaned apt cache
|
||||
4. Cleaned temp directories (/tmp, /var/tmp)
|
||||
5. Pruned Docker images, volumes, and cache
|
||||
6. Analyzed container storage usage
|
||||
7. Generated SonarQube audit report
|
||||
8. Identified stopped containers for cleanup
|
||||
|
||||
⚠️ IMMEDIATE ACTIONS REQUIRED:
|
||||
1. [ ] SSH to proxmox-00 and verify root FS space freed
|
||||
Command: df -h /
|
||||
2. [ ] Review stopped containers and decide keep/remove
|
||||
3. [ ] Monitor dlx-docker on proxmox-01 (currently 81% full)
|
||||
4. [ ] Schedule SonarQube data cleanup if needed
|
||||
|
||||
📊 CAPACITY TARGETS:
|
||||
- proxmox-00 root: Target <70% (currently 84%)
|
||||
- proxmox-01 dlx-docker: Target <75% (currently 81%)
|
||||
- SonarQube: Keep <75% if possible
|
||||
|
||||
🔄 AUTOMATION RECOMMENDATIONS:
|
||||
1. Create logrotate config for persistent log management
|
||||
2. Schedule weekly: docker system prune -f
|
||||
3. Schedule monthly: journalctl --vacuum=time:60d
|
||||
4. Set up monitoring alerts at 75%, 85%, 95% capacity
