# Workstation Health Report: mw-manjaro-pf
|
|
|
|
## System Specifications
|
|
|
|
- **CPU**: AMD Ryzen 7 2700X (16 threads) @ 3.9GHz max
|
|
- **Memory**: 62 GiB DDR5-3200 MHz
|
|
- **Primary Disk**: 512 GB NVMe SSD (Samsung MZvl2512HCJQ)
|
|
- **Secondary Disk**: 500 GB SATA SSD (Samsung 840 EVO) -> `/home/mw/models`
|
|
- **OS**: Manjaro Linux (Kernel 6.12)
|
|
|
|
## Current Health Status (2026-03-17 23:21 CET)
|
|
|
|
- **Uptime**: ~1 hour, 7 minutes (post-reboot due to OOM crash at 18:33)
|
|
- **Load Average**: 0.40, 0.50, 1.45 (very low)
|
|
- **Memory**: 7.9 GiB used / 62 GiB total (12%)
|
|
- **Swap**: 0 B used / 16 GiB (0%)
|
|
- **zswap**: Active (zstd/zsmalloc, 30% pool)
|
|
- **Disk Usage (/)**: 84% (371G used, 74G free)
|
|
- **OOM Protection**: `systemd-oomd` active, monitoring `/user.slice`
|
|
- **Kernel Optimizations**:
|
|
- mglru: Active
|
|
- Transparent hugepages: `madvise`
|
|
- Proactive reclaim: `watermark_scale_factor 100`
|
|
- Dirty bytes: `dirty_ratio=10`, `dirty_background_ratio=5`
|
|
- **Maintenance**:
|
|
- Crash analysis performed for 2026-03-17 incident
|
|
- S.M.A.R.T. hardware check passed for NVMe

## Crashlog Analysis (2026-03-17)
|
|
|
|
### Recent Errors (from journalctl)
|
|
|
|
No errors in the last hour from `journalctl -p err`
|
|
|
|
### OOM Events
|
|
|
|
- **15:06:06 CET**: Node.js process (PID 122570, 122573, 122574, 122575, 122625) dumped core due to OOM
|
|
- These appear to be Cline/agent-related processes that exhausted memory
|
|
- Systemd-oomd correctly intervened and terminated the processes
|
|
|
|
### Kernel Warnings (Boot)
|
|
|
|
- **VMSCAPE**: SMT advisory - mitigation available (enable STIBP for full protection)
|
|
- **ATA link failures**: ata3/4/7/8 failed to resume (idle SATA ports)
|
|
- **Samsung 840 EVO quirks**: noncqtrim, zeroaftertrim, nodmalog (normal for older SSD)
|
|
- **NVIDIA taint**: Proprietary driver (expected)
|
|
- **UVC webcam warnings**: Non-critical (device firmware)
|
|
- **Pipewire Broken Pipe**: Video device initialization issues (non-critical)
|
|
|
|
### Failed Services
|
|
|
|
- `archlinux-keyring-wkd-sync.service`: Failed (non-critical, keyring sync)
|
|
|
|
### Docker
|
|
|
|
- **Status**: 6 containers running
|
|
- **No zombie containers detected**
|
|
|
|
### Health Check Script Results
|
|
|
|
```text
|
|
Root partition: 78% used
|
|
Git status: Dirty (34 changes) - workstation-health.md modified
|
|
Docker: 6 containers running
|
|
Uptime: ~1 hour, 7 minutes
|
|
```
|
|
|
|
## Recommendations
|
|
|
|
1. **Monitor Node.js memory**: Today's OOM crash involved multiple Cline-related node processes.
|
|
Consider investigating if agent sessions are consuming excessive memory.
|
|
2. **Replace Samsung 840 EVO**: Currently applies SATA quirks (noncqtrim, zeroaftertrim, nodmalog).
|
|
Action: No action needed (non-critical, working as expected)
|
|
3. **Monitor memory**: 12% usage is very healthy. Current state is stable.
|
|
|
|
## Next Steps
|
|
|
|
1. Consider setting up automated crash monitoring for high-memory applications
|
|
2. Run morning health check script daily: `/home/mw/internal/mw-pfeddersheim-workstation/scripts/morning-health-check.sh` |
