From 90ed5c1edbecbf8cb111ed50706a3cef1f73cb1b Mon Sep 17 00:00:00 2001 From: directlx Date: Sun, 8 Feb 2026 13:22:53 -0500 Subject: [PATCH] Add storage remediation playbooks and comprehensive audit documentation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit introduces a complete storage remediation solution for critical Proxmox cluster issues: Playbooks (4 new): - remediate-storage-critical-issues.yml: Log cleanup, Docker prune, audits - remediate-docker-storage.yml: Deep Docker cleanup with automation - remediate-stopped-containers.yml: Safe container removal with backups - configure-storage-monitoring.yml: Proactive monitoring and alerting Critical Issues Addressed: - proxmox-00 root FS: 84.5% → <70% (frees 10-15 GB) - proxmox-01 dlx-docker: 81.1% → <75% (frees 50-150 GB) - Unused containers: 1.2 TB allocated → removable - Storage gaps: Automated monitoring with 75/85/95% thresholds Documentation (3 new): - STORAGE-AUDIT.md: Comprehensive capacity analysis and hardware inventory - STORAGE-REMEDIATION-GUIDE.md: Step-by-step execution with timeline - REMEDIATION-SUMMARY.md: Quick reference for playbooks and results Features: ✓ Dry-run modes for safety ✓ Configuration backups before removal ✓ Automated weekly maintenance scheduled ✓ Continuous monitoring with syslog integration ✓ Prometheus metrics export ready ✓ Complete troubleshooting guide Expected Results: - Total space freed: 1-2 TB - Automated cleanup prevents regrowth - Real-time capacity alerts - Monthly audit cycles Co-Authored-By: Claude Haiku 4.5 --- docs/REMEDIATION-SUMMARY.md | 379 +++++++++++++ docs/STORAGE-AUDIT.md | 380 +++++++++++++ docs/STORAGE-REMEDIATION-GUIDE.md | 499 ++++++++++++++++++ playbooks/configure-storage-monitoring.yml | 384 ++++++++++++++ playbooks/remediate-docker-storage.yml | 286 ++++++++++ playbooks/remediate-stopped-containers.yml | 280 ++++++++++ .../remediate-storage-critical-issues.yml | 368 +++++++++++++ 7 files changed, 2576 insertions(+) create mode 100644 docs/REMEDIATION-SUMMARY.md create mode 100644 docs/STORAGE-AUDIT.md create mode 100644 docs/STORAGE-REMEDIATION-GUIDE.md create mode 100644 playbooks/configure-storage-monitoring.yml create mode 100644 playbooks/remediate-docker-storage.yml create mode 100644 playbooks/remediate-stopped-containers.yml create mode 100644 playbooks/remediate-storage-critical-issues.yml diff --git a/docs/REMEDIATION-SUMMARY.md b/docs/REMEDIATION-SUMMARY.md new file mode 100644 index 0000000..0c67a42 --- /dev/null +++ b/docs/REMEDIATION-SUMMARY.md @@ -0,0 +1,379 @@ +# Storage Remediation Playbooks Summary + +**Created**: 2026-02-08 +**Status**: Ready for deployment + +--- + +## Overview + +Four Ansible playbooks have been created to remediate critical storage issues identified in the Proxmox cluster storage audit. + +--- + +## Playbooks Created + +### 1. `remediate-storage-critical-issues.yml` + +**Location**: `playbooks/remediate-storage-critical-issues.yml` + +**Purpose**: Address immediate critical and high-priority issues + +**Targets**: +- proxmox-00 (root filesystem at 84.5%) +- proxmox-01 (dlx-docker at 81.1%) +- All nodes (SonarQube, stopped containers audit) + +**Actions**: +- Compress journal logs (>30 days) +- Remove old syslog files (>90 days) +- Clean apt cache and temp files +- Prune Docker images, volumes, and build cache +- Audit SonarQube disk usage +- Report on stopped containers + +**Expected space freed**: +- proxmox-00: 10-15 GB +- proxmox-01: 20-50 GB +- Total: 30-65 GB + +**Execution time**: 5-10 minutes + +--- + +### 2. `remediate-docker-storage.yml` + +**Location**: `playbooks/remediate-docker-storage.yml` + +**Purpose**: Detailed Docker storage cleanup for proxmox-01 + +**Targets**: +- proxmox-01 (Docker host) +- dlx-docker LXC container + +**Actions**: +- Analyze container and image sizes +- Identify dangling resources +- Remove unused images, volumes, and build cache +- Run aggressive system prune (`docker system prune -a -f --volumes`) +- Configure automated weekly cleanup +- Setup hourly monitoring with alerting +- Create log rotation policies + +**Expected space freed**: +- 50-150 GB depending on usage patterns + +**Automated maintenance**: +- Weekly: `docker system prune -af --volumes` +- Hourly: Capacity monitoring and alerting +- Daily: Log rotation with 7-day retention + +**Execution time**: 10-15 minutes + +--- + +### 3. `remediate-stopped-containers.yml` + +**Location**: `playbooks/remediate-stopped-containers.yml` + +**Purpose**: Safely remove unused LXC containers + +**Targets**: +- All Proxmox hosts +- 15 stopped containers (1.2 TB allocated) + +**Actions**: +- Audit all containers and identify stopped ones +- Generate size/allocation report +- Create configuration backups before removal +- Safely remove containers (dry-run by default) +- Provide recovery guide and instructions +- Verify space freed + +**Containers targeted for removal** (recommendations): +- dlx-mysql-02 (108): 200 GB +- dlx-mysql-03 (109): 200 GB +- dlx-mattermost (107): 32 GB +- dlx-nocodb (116): 100 GB +- dlx-swarm-01/02/03: 195 GB combined +- dlx-kube-01/02/03: 150 GB combined + +**Total recoverable**: 877+ GB + +**Safety features**: +- Dry-run mode by default (`dry_run: true`) +- Config backups created before deletion +- Recovery instructions provided +- Containers listed for manual approval + +**Execution time**: 2-5 minutes + +--- + +### 4. `configure-storage-monitoring.yml` + +**Location**: `playbooks/configure-storage-monitoring.yml` + +**Purpose**: Set up proactive storage monitoring and alerting + +**Targets**: +- All Proxmox hosts (proxmox-00, 01, 02) + +**Actions**: +- Create monitoring scripts: + -
