why did disk 10 drop from the array, smart looks fine


- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- verify: Verify that a code change actually does what it's supposed to by running the app and observing behavior. Use when asked to verify a PR, confirm a fix works, test a change manually, check that a feature works, or validate local changes before pushing.
- code-review: Review the current diff for correctness bugs and reuse/simplification/efficiency cleanups at the given effort level (low/medium: fewer, high-confidence findings; high→max: broader coverage, may include uncertain findings; ultra: deep multi-agent review in the cloud). Pass --comment to post findings as inline PR comments, or --fix to apply the findings to the working tree after the review.
- simplify: Review the changed code for reuse, simplification, efficiency, and altitude cleanups, then apply the fixes. Quality only — it does not hunt for bugs; use /code-review for that.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- schedule: Create, update, list, or run scheduled remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run ("run this once at 3pm", "remind me to check X tomorrow").
- claude-api: Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration.
TRIGGER — read BEFORE opening the target file; don't skip because it "looks like a one-liner" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens).
SKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).
- run: Launch and drive this project's app to see a change working. Use when asked to run, start, or screenshot the app, or to confirm a change works in the real app (not just tests). First looks for a project skill that already covers launching the app; otherwise falls back to built-in patterns per project type (CLI, server, TUI, Electron, browser-driven, library).
- init: Initialize a new CLAUDE.md file with codebase documentation
- review: Review a pull request
- security-review: Complete a security review of the pending changes on the current branch

Let me check the system logs and disk status to investigate.


Bash

cat /var/log/syslog | grep -i "disk10\|disk 10\|md10\|sysfs\|disable\|dropped\|error\|failed\|read error\|write error" | tail -100

Check syslog for disk 10 errors

Here's the full picture:

**Root cause: the drive momentarily disappeared off the bus**, not a media failure.

On Jun 8 at 23:54, `sdl` started returning `hostbyte=0x0b` (BUS_BUSY/soft error) and `hostbyte=0x0e` (NO_CONNECT) — meaning the HBA lost communication with the drive mid-I/O. The MD driver hit 290 errors and disabled it. SMART is clean because there are zero reallocated sectors, zero CRC errors — the disk platters are fine.

The 16,726 ATA errors in SMART all occurred at the same power-on hour (15,804h), so they're all from that one event burst, not accumulated wear.

The drive is on SAS phy 19, enclosure slot 11. The most likely culprits in order:
1. **Bad/unseated cable or backplane connector** at slot 11 — most common cause for this exact pattern
2. **SAS expander port hiccup** — single-drive event makes a full expander reset unlikely, but possible
3. **Momentary power dip** to that backplane slot

**Fix path:**
1. Stop the array, reseat the SATA/SAS cable at both the backplane and HBA ends for slot 11. Try swapping the cable if you have a spare.
2. Restart the array — Unraid will see it as disabled but present.
3. Use **Tools > New Config** or the **Trust** option to bring it back without a full rebuild (parity is intact, no media errors).

The PCIe AER errors flooding the log are a separate issue — that's your ASMedia USB controller (`0000:03:00.0`) passed through to a VM via vfio, and it's unrelated to the disk drop.

Based on my search results, here's what I found about 12TB hard drive prices from major retailers:

**Available Options:**

Amazon offers a wide selection of 12TB hard drives for NAS, desktop, and external storage from trusted brands, and Newegg carries multiple 12TB models including Seagate IronWolf and Toshiba N300 options.

**Notable Price Points:**

One Cyber Monday deal offered a 12TB Helium-filled NAS hard drive for $16.67 per TB, which would work out to approximately $200 for the full drive. Additionally, a 12TB MDD HC520 refurbished hard disk drive with a 5-year warranty was available for $89.99 on Amazon, though this is a refurbished enterprise model.

For current real-time pricing, I recommend visiting the retailer pages directly:
- **Amazon**: amazon.com/12tb-hard-drive
- **Newegg**: newegg.com/p/pl?d=12tb+hard+drive

Prices fluctuate regularly based on sales and promotions, so checking these sites directly will give you the most up-to-date pricing information.

# Cheapest 12TB Internal Hard Drives

Based on the disk pricing data, here are the most affordable 12TB internal options:

| Price | $/TB | Model | Type |
|-------|------|-------|------|
| $300 | $0.025 | Toshiba MG Series Enterprise 12TB | SATA HDD |
| $300 | $0.025 | MDD HC520 HUH721212ALE601 | SATA HDD |
| $310 | $0.026 | Seagate Exos x12 ST12000NM0127 | SATA HDD |
| $310 | $0.026 | Toshiba MG07ACA12TE | SATA HDD |

| $325 | $0.027 | HGST Ultrastar He12 HUH721212ALE601 | SATA HDD |
| $329 | $0.027 | Dell/Seagate Exos X16 ST12000NM005G | SATA HDD |
| $330 | $0.027 | HGST DC HC520 HUH721212ALE601 | SATA HDD |
| $330 | $0.027 | Seagate Exos x12 ST12000NM0007 | SATA HDD |

**All listings available through Amazon.com** with prices reflecting renewed/used conditions where applicable. Most entries represent enterprise-grade drives suitable for NAS and server applications.


The page data looks a bit off from the parser — the $/TB column got mangled. Based on what I can see, current 12TB pricing is roughly:

**Cheapest new options (~$180–$220):**
- **Seagate IronWolf 12TB** (ST12000VN0008) — NAS-rated, ~$180–$200 on Amazon
- **WD Red Plus 12TB** — similar range

**Cheapest refurb/recertified (~$90–$130):**
- **MDD recertified HGST HC520 (HUH721212ALE600/601)** — enterprise helium drive, 5-year warranty, frequently ~$90–$110 on Amazon. This is the same underlying drive as your current Toshiba-class enterprise tier.

Your existing disk (Toshiba MG07ACA12TEY) is a solid enterprise drive. Given that SMART is clean with zero reallocated sectors, I'd reseat the cable first before ordering anything — there's a good chance this isn't a dying disk. But if you want a hot spare on the shelf, the MDD recertified HGST is the best value by far at that capacity.

Check [diskprices.com](https://diskprices.com/?locale=us&capacity=12,12&disk_types=internal_hdd) directly for live sorted pricing — it's the best aggregator for this.

Investigating why disk 10 dropped from the array and whether it needs replacing. Reseat the cable at backplane slot 11 first before buying anything. (disable recaps in /config)
