=========================================
|

```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Insufficient disk space
|
||||
|
||||
Check available space:
|
||||
```bash
|
||||
ansible all -m shell -a "df -h /var/backups"
|
||||
```
|
||||
|
||||
Clean old backups:
|
||||
```bash
|
||||
ansible-playbook playbooks/backup.yml --tags cleanup
|
||||
```
|
||||
|
||||
### Database backup fails
|
||||
|
||||
Check database connectivity:
|
||||
```bash
|
||||
# MySQL
|
||||
ansible all -m shell -a "mysqldump --version"
|
||||
|
||||
# PostgreSQL
|
||||
ansible all -m shell -a "sudo -u postgres pg_dumpall --version"
|
||||
```
|
||||
|
||||
### Backup integrity check fails
|
||||
|
||||
Manually verify:
|
||||
```bash
|
||||
ansible all -m shell -a "gzip -t /var/backups/config/*.gz"
|
||||
```
|
||||
|
||||
## Restore from Backup
|
||||
|
||||
See [Disaster Recovery Playbook](disaster_recovery.md) for restoration procedures.
|
||||
|
||||
```bash
|
||||
# Quick restore example
|
||||
ansible-playbook playbooks/disaster_recovery.yml \
|
||||
--limit failed_host \
|
||||
--extra-vars "dr_backup_date=2025-01-11"
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Test restores regularly** - Backups are useless if they can't be restored
|
||||
2. **Monitor backup sizes** - Watch for unexpected growth
|
||||
3. **Use remote storage** - Don't keep backups only on the same host
|
||||
4. **Verify backups** - Always enable verification
|
||||
5. **Document retention** - Follow compliance requirements
|
||||
6. **Encrypt sensitive backups** - Use encryption for databases
|
||||
7. **Schedule appropriately** - Run during low-activity periods
|
||||
|
||||
## Quick Reference Commands
|
||||
|
||||
```bash
|
||||
# Full backup with verification
|
||||
ansible-playbook playbooks/backup.yml \
|
||||
--extra-vars "backup_type=full"
|
||||
|
||||
# Configuration only
|
||||
ansible-playbook playbooks/backup.yml --tags config
|
||||
|
||||
# Databases only
|
||||
ansible-playbook playbooks/backup.yml --tags databases
|
||||
|
||||
# Cleanup old backups (30+ days)
|
||||
ansible-playbook playbooks/backup.yml --tags cleanup
|
||||
|
||||
# Custom retention (90 days)
|
||||
ansible-playbook playbooks/backup.yml --tags cleanup \
|
||||
--extra-vars "backup_retention_days=90"
|
||||
|
||||
# Dry-run
|
||||
ansible-playbook playbooks/backup.yml --check
|
||||
|
||||
# Specific host only
|
||||
ansible-playbook playbooks/backup.yml --limit hostname
|
||||
|
||||
# Production environment
|
||||
ansible-playbook -i inventories/production playbooks/backup.yml
|
||||
```

# Disaster Recovery Playbook Cheatsheet
|
||||
|
||||
Quick reference for using the disaster recovery playbook.
|
||||
|
||||
## ⚠️ WARNING
|
||||
|
||||
This playbook performs **DESTRUCTIVE OPERATIONS**. Only use when recovering from a disaster or system failure.
|
||||
|
||||
## Quick Start
|
||||
|
||||
```bash
|
||||
# Assess damage only (safe)
|
||||
ansible-playbook playbooks/disaster_recovery.yml --limit failed_host --tags assess
|
||||
|
||||
# Full recovery
|
||||
ansible-playbook playbooks/disaster_recovery.yml --limit failed_host \
|
||||
--extra-vars "dr_backup_date=2025-01-11"
|
||||
```
|
||||
|
||||
## Prerequisites
|
||||
|
||||
1. **Backups available** - Ensure backups exist in `/var/backups/`
|
||||
2. **System accessible** - Host must be reachable via SSH
|
||||
3. **Confirmation ready** - You'll need to type "RECOVER" to proceed

||||
# Check backup dates
|
||||
ansible failed_host -m shell -a "ls /var/backups/*/backup_manifest_*.txt"
|
||||
|
||||
# View backup manifest
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Backup not found
|
||||
|
||||
```bash
|
||||
# Check backup location
|
||||
ansible failed_host -m shell -a "ls -la /var/backups/"
|
||||
|
||||
# Restore from remote backup server
|
||||
ansible failed_host -m synchronize \
|
||||
-a "src=/mnt/backup-server/backups/ dest=/var/backups/ mode=pull"
|
||||
```
|
||||
|
||||
### SSH connection lost during recovery
|
||||
|
||||
The SSH service restart is designed to maintain connections. If lost:
|
||||
|
||||
```bash
|
||||
# Wait 60 seconds for SSH to restart
|
||||
# Retry connection
|
||||
|
||||
ansible failed_host -m ping
|
||||
```
|
||||
|
||||
### Service won't start after recovery
|
||||
|
||||
```bash
|
||||
# Check service status
|
||||
ansible failed_host -m shell -a "systemctl status service_name"
|
||||
|
||||
# Check service logs
|
||||
ansible failed_host -m shell -a "journalctl -u service_name -n 50"
|
||||
```
|
||||
|
||||
### SELinux blocking services
|
||||
|
||||
```bash
|
||||
# Relabel SELinux contexts
|
||||
ansible failed_host -m shell -a "restorecon -R /etc /var"
|
||||
```
|
||||
|
||||
## Post-Recovery Checklist
|
||||
|
||||
- [ ] Verify all services running
|
||||
- [ ] Test application functionality
|
||||
- [ ] Check disk space
|
||||
- [ ] Review system logs
|
||||
- [ ] Verify backups are current
|
||||
- [ ] Update documentation
|
||||
- [ ] Notify stakeholders
|
||||
- [ ] Conduct lessons learned review
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Test recovery procedures regularly** - Monthly DR drills
|
||||
2. **Document recovery time objectives (RTO)** - Know your targets
|
||||
3. **Keep backups off-site** - Don't rely on local backups only
|
||||
4. **Verify backup integrity** - Test restores before disasters
|
||||
5. **Maintain runbooks** - Document specific recovery procedures
|
||||
6. **Practice on staging** - Test recovery in non-production first
|
||||
7. **Have communication plan** - Know who to notify
|
||||

### Using jq for Data Extraction
|
||||
|
||||
```bash
|
||||
# Get CPU models across all hosts
|
||||
jq -r '.cpu.model' ./stats/machines/*/system_info.json
|
||||
|
||||
# Get memory usage
|
||||
jq -r '"\(.host_info.fqdn): \(.memory.usage_percent)%"' \
|
||||
./stats/machines/*/system_info.json
|
||||
|
||||
# Find hypervisors
|
||||
jq -r 'select(.hypervisor.is_hypervisor == true) | .host_info.fqdn' \
|
||||
./stats/machines/*/system_info.json
|
||||
|
||||
# Find virtual machines
|
||||
jq -r 'select(.hypervisor.is_virtual == true) | .host_info.fqdn' \
|
||||
./stats/machines/*/system_info.json
|
||||
|
||||
# Get OS distribution
|
||||
jq -r '"\(.host_info.fqdn): \(.system.distribution) \(.system.distribution_version)"' \
|
||||
./stats/machines/*/system_info.json
|
||||
|
||||
# Find hosts with high CPU count
|
||||
jq -r 'select(.cpu.count.vcpus > 8) | "\(.host_info.fqdn): \(.cpu.count.vcpus) vCPUs"' \
|
||||
./stats/machines/*/system_info.json
|
||||
|
||||
# Find hosts with low disk space
|
||||
jq -r 'select(.disk.usage_percent > 80) | "\(.host_info.fqdn): \(.disk.usage_percent)%"' \
|
||||
./stats/machines/*/system_info.json
|
||||
```
|
||||
|
||||
### Generate Reports
|
||||
|
||||
```bash
|
||||
# CSV export: Hostname, OS, CPU, Memory
|
||||
jq -r '["FQDN","OS","CPU Cores","Memory GB"],
|
||||
([.host_info.fqdn, .system.distribution,
|
||||
.cpu.count.vcpus, (.memory.total_mb/1024|round)]) | @csv' \
|
||||
./stats/machines/*/system_info.json > infrastructure_report.csv
|
||||
|
||||
# Count CPUs across infrastructure
|
||||
jq -s 'map(.cpu.count.total_cores | tonumber) | add' \
|
||||
./stats/machines/*/system_info.json
|
||||
|
||||
# Total memory across infrastructure (GB)
|
||||
jq -s 'map(.memory.total_mb | tonumber) | add / 1024 | round' \
|
||||
./stats/machines/*/system_info.json
|
||||
|
||||
# List GPU-enabled hosts
|
||||
jq -r 'select(.gpu.detected == true) | "\(.host_info.fqdn): \(.gpu.devices[0].model)"' \
|
||||
./stats/machines/*/system_info.json
|
||||
|
||||
# SELinux status report
|
||||
jq -r '"\(.host_info.fqdn): SELinux \(.security.selinux)"' \
|
||||
./stats/machines/*/system_info.json | grep -v "N/A"
|
||||
|
||||
# AppArmor status report
|
||||
jq -r '"\(.host_info.fqdn): AppArmor \(.security.apparmor)"' \
|
||||
./stats/machines/*/system_info.json | grep -v "N/A"

host=$(jq -r '.host_info.fqdn' "$stats_file")
|
||||
cpu=$(jq -r '.cpu.count.vcpus' "$stats_file")
|
||||
mem=$(jq -r '.memory.total_mb' "$stats_file")
|
||||
|
||||
cat <<EOF > /var/lib/node_exporter/textfile_collector/${host}.prom
|
||||
# HELP system_info_cpu_count Number of CPU cores
|
||||
# TYPE system_info_cpu_count gauge
|
||||
system_info_cpu_count{host="$host"} $cpu
|
||||
|
||||
# HELP system_info_memory_mb Total memory in MB
|
||||
# TYPE system_info_memory_mb gauge
|
||||
system_info_memory_mb{host="$host"} $mem
|
||||
EOF
|
||||
done
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Check Playbook Execution
|
||||
|
||||
```bash
|
||||
# Dry-run (check mode)
|
||||
ansible-playbook playbooks/gather_system_info.yml --check
|
||||
|
||||
# Verbose output
|
||||
ansible-playbook playbooks/gather_system_info.yml -v
|
||||
|
||||
# Very verbose (debug)
|
||||
ansible-playbook playbooks/gather_system_info.yml -vvv
|
||||
|
||||
# Single host debugging
|
||||
ansible-playbook playbooks/gather_system_info.yml \
|
||||
--limit problematic-host -vvv
|
||||
```
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Missing packages**
|
||||
```bash
|
||||
# Install packages manually first
|
||||
ansible all -m package -a "name=lshw,dmidecode,pciutils state=present" --become
|
||||
|
||||
# Or run with install tag only
|
||||
ansible-playbook playbooks/gather_system_info.yml --tags install
|
||||
```
|
||||
|
||||
**Permission errors**
|
||||
```bash
|
||||
# Ensure become is enabled
|
||||
ansible-playbook playbooks/gather_system_info.yml --become
|
||||
|
||||
# Check sudo access
|
||||
ansible all -m ping --become
|
||||
```
|
||||
|
||||
**Statistics not saved**
|
||||
```bash
|
||||
# Check if directory exists
|
||||
ls -la ./stats/machines/
|
||||
|
||||
# Check disk space
|
||||
df -h .
|
||||
|
||||
# Create directory manually
|
||||
mkdir -p ./stats/machines
|
||||
|
||||
# Specify alternative directory
|
||||
ansible-playbook playbooks/gather_system_info.yml \
|
||||
-e "system_info_stats_base_dir=/tmp/stats"
|
||||
```
|
||||
|
||||
**Slow execution**
|
||||
```bash
|
||||
# Skip slow operations
|
||||
ansible-playbook playbooks/gather_system_info.yml \
|
||||
--skip-tags install,network
|
||||
|
||||
# Disable GPU gathering
|
||||
ansible-playbook playbooks/gather_system_info.yml \
|
||||
-e "system_info_gather_gpu=false"
|
||||
|
||||
# Increase parallelism
|
||||
ansible-playbook playbooks/gather_system_info.yml -f 20
|
||||
```
|
||||
|
||||
### Validation
|
||||
|
||||
```bash
|
||||
# Verify JSON files are valid
|
||||
for f in ./stats/machines/*/system_info.json; do
|
||||
echo "Checking $f"
|
||||
jq empty "$f" && echo "✓ OK" || echo "✗ INVALID"
|
||||
done
|
||||
|
||||
# Check for missing files
|
||||
for host in $(ansible all --list-hosts | tail -n +2); do
|
||||
if [ ! -f "./stats/machines/${host}/system_info.json" ]; then
|
||||
echo "Missing: $host"
|
||||
fi
|
||||
done
|
||||
|
||||
# Verify data completeness
|
||||
jq -r 'if .cpu == null then "Missing CPU data" else "OK" end' \
|
||||
./stats/machines/*/system_info.json
|
||||
```
|
||||
|
||||
## Performance Optimization
|
||||
|
||||
### Parallel Execution
|
||||
|
||||
```bash
|
||||
# Default (5 hosts at a time)
|
||||
ansible-playbook playbooks/gather_system_info.yml
|
||||
|
||||
# Increase parallelism
|
||||
ansible-playbook playbooks/gather_system_info.yml -f 20
|
||||
|
||||
# Serial execution (one at a time)
|
||||
ansible-playbook playbooks/gather_system_info.yml -f 1
|
||||
```
|
||||
|
||||
### Skip Slow Tasks
|
||||
|
||||
```bash
|
||||
# Skip package installation
|
||||
ansible-playbook playbooks/gather_system_info.yml --skip-tags install
|
||||
|
||||
# Skip network gathering
|

||||
# Run maintenance and check reboot status
|
||||
ansible-playbook playbooks/maintenance.yml
|
||||
|
||||
# Look for: "Reboot required: true" in output
|
||||
```
|
||||
|
||||
### Perform Reboot
|
||||
|
||||
```bash
|
||||
# WARNING: This will reboot hosts one at a time!
|
||||
ansible-playbook playbooks/maintenance.yml --tags reboot
|
||||
|
||||
# Reboot specific environment
|
||||
ansible-playbook -i inventories/staging playbooks/maintenance.yml --tags reboot
|
||||
|
||||
# Control reboot parallelism
|
||||
ansible-playbook playbooks/maintenance.yml --tags reboot \
|
||||
--extra-vars "maintenance_serial=1"
|
||||
```
|
||||
|
||||
## Serial Execution
|
||||
|
||||
Control how many hosts are updated simultaneously:
|
||||
|
||||
```bash
|
||||
# Update all hosts in parallel (default)
|
||||
ansible-playbook playbooks/maintenance.yml
|
||||
|
||||
# Update one host at a time
|
||||
ansible-playbook playbooks/maintenance.yml \
|
||||
--extra-vars "maintenance_serial=1"
|
||||
|
||||
# Update 25% of hosts at a time
|
||||
ansible-playbook playbooks/maintenance.yml \
|
||||
--extra-vars "maintenance_serial=25%"
|
||||
```
|
||||
|
||||
## Output and Logs
|
||||
|
||||
Logs saved to: `./logs/maintenance/<date>/<hostname>_maintenance.log`
|
||||
|
||||

|
||||
=========================================
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Package updates fail
|
||||
|
||||
Check update repositories:
|
||||
```bash
|
||||
# Debian/Ubuntu
|
||||
ansible all -m shell -a "apt update"
|
||||
|
||||
# RHEL/CentOS
|
||||
ansible all -m shell -a "dnf check-update"
|
||||
```
|
||||
|
||||
### Disk space warnings
|
||||
|
||||
Free up space manually before maintenance:
|
||||
```bash
|
||||
ansible-playbook playbooks/maintenance.yml --tags cleanup
|
||||
```
|
||||
|
||||
### Service not running after update
|
||||
|
||||
Check service status:
|
||||
```bash
|
||||
ansible all -m shell -a "systemctl status <service>"
|
||||
```
|
||||
|
||||
## Scheduling Maintenance
|
||||
|
||||
### Cron Example
|
||||
|
||||
```bash
|
||||
# Daily security updates at 2 AM
|
||||
0 2 * * * cd /opt/ansible && ansible-playbook playbooks/maintenance.yml
|
||||
```
|
||||
|
||||
### SystemD Timer Example
|
||||
|
||||
```ini
|
||||
# /etc/systemd/system/ansible-maintenance.timer
|
||||
[Unit]
|
||||
Description=Ansible Maintenance
|
||||
|
||||
[Timer]
|
||||
OnCalendar=daily
|
||||
Persistent=true
|
||||
|
||||
[Install]
|
||||
WantedBy=timers.target
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Test in staging first** - Always run in staging before production
|
||||
2. **Monitor during updates** - Watch for failures
|
||||
3. **Check reboot requirements** - Plan reboots during maintenance windows
|
||||
4. **Review logs** - Check maintenance logs for issues
|
||||
5. **Use serial execution** for production - Update hosts gradually
|
||||
6. **Schedule appropriately** - Run during low-traffic periods
|
||||
|
||||
## Quick Reference Commands
|
||||
|
||||
```bash
|
||||
# Dry-run (no changes)
|
||||
ansible-playbook playbooks/maintenance.yml --check
|
||||
|
||||
# Staging environment
|
||||
ansible-playbook -i inventories/staging playbooks/maintenance.yml
|
||||
|
||||
# Production (one host at a time)
|
||||
ansible-playbook -i inventories/production playbooks/maintenance.yml \
|
||||
--extra-vars "maintenance_serial=1"
|
||||
|
||||
# Updates only, no cleanup
|
||||
ansible-playbook playbooks/maintenance.yml --tags updates
|
||||
|
||||
# Full upgrade (non-security too)
|
||||
ansible-playbook playbooks/maintenance.yml \
|
||||
--extra-vars "maintenance_security_only=false"
|
||||
|
||||
# Cleanup only
|
||||
ansible-playbook playbooks/maintenance.yml --tags cleanup
|
||||
|
||||
# Check if reboot needed
|
||||
ansible-playbook playbooks/maintenance.yml --tags verify
|
||||
|
||||
# Reboot if needed
|
||||
ansible-playbook playbooks/maintenance.yml --tags reboot

## Troubleshooting
|
||||
|
||||
### No audit reports generated
|
||||
|
||||
Check report directory exists:
|
||||
```bash
|
||||
ls -la ./reports/security_audit/
|
||||
```
|
||||
|
||||
### Failed checks
|
||||
|
||||
Review specific failed checks:
|
||||
```bash
|
||||
ansible-playbook playbooks/security_audit.yml -vv
|
||||
```
|
||||
|
||||
### Permission denied
|
||||
|
||||
Ensure become is enabled:
|
||||
```bash
|
||||
ansible-playbook playbooks/security_audit.yml --become
|
||||
```
|
||||
|
||||
## Integration with CI/CD
|
||||
|
||||
```yaml
|
||||
# GitLab CI example
|
||||
security_audit:
|
||||
stage: compliance
|
||||
script:
|
||||
- ansible-playbook playbooks/security_audit.yml
|
||||
only:
|
||||
- schedules
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Schedule regular audits** - Run weekly or after changes
|
||||
2. **Review reports** - Don't just run audits, act on findings
|
||||
3. **Track trends** - Compare audit results over time
|
||||
4. **Document exceptions** - Note why certain checks fail
|
||||
5. **Remediate findings** - Create tasks to fix issues
|
||||
|
||||
## Quick Reference Commands
