+# 32 — Nullstone Storage Upgrade Plan
+
+> Status: PLAN (2026-05-10). Hardware purchase + install pending.
+
+## Why
+
+ARRFLIX library growth — Rick and Morty S02-S08 import (~105 GB) would push `/home` from 70 % → 92 % full. Tight margin for transcodes, logs, future imports. Pre-emptive upgrade beats emergency cleanup.
+
+## Current state
+
+| Item | Value |
+|---|---|
+| Drive | Intel SSDPEKKF512G8 NVMe 512 GB (single) |
+| Slot | 1 NVMe (`nvme0n1`) |
+| LVM VG | `keystone-vg`, fully allocated (475 GB) |
+| LV `/home` | 406.2 GB, 263 GB used, 117 GB free (70 %) |
+| LV `/`, `/var`, `/tmp`, swap | 30/11/3/24 GB |
+| Mobo | MSI X470 Gaming Plus Max (MS-7B79) |
+| **Free slots** | **1× M.2 (M2_2)**, **6× SATA ports** |
+
+Mobo has two M.2 slots:
+- `M2_1` — PCIe 3.0 ×4, **occupied** (Intel 512 GB)
+- `M2_2` — PCIe 2.0 ×4 / SATA, **free**
+
+## Recommended path — 2nd NVMe in M2_2
+
+| Capacity | Approx cost | Recommended |
+|---|---|---|
+| 1 TB NVMe | ~£60 | adequate |
+| 2 TB NVMe | ~£130 | **best** — leaves headroom for full Disney+ / Star Wars catalogue |
+| 4 TB NVMe | ~£250 | long-term, future-proof |
+
+Specs: NVMe PCIe 3.0 ×4 (M.2 2280). Brand: WD SN770, Samsung 990 EVO, Crucial P310, Lexar NM790. M2_2 is PCIe 2.0 — drive will negotiate down (still ~1.5 GB/s — plenty for media).
+
+### Procedure
+
+1. Power off nullstone.
+2. Open case, install drive in M2_2 slot.
+3. Boot.
+4. Verify: `lsblk` should show new `nvme1n1`.
+5. Partition: `sudo parted /dev/nvme1n1 mklabel gpt && sudo parted /dev/nvme1n1 mkpart primary 0% 100%`
+6. Add as LVM PV: `sudo pvcreate /dev/nvme1n1p1`
+7. Extend VG: `sudo vgextend keystone-vg /dev/nvme1n1p1`
+8. Extend LV: `sudo lvextend -l +100%FREE /dev/keystone-vg/home`
+9. Grow filesystem online: `sudo resize2fs /dev/keystone-vg/home`
+10. Verify: `df -h /home` should show new size, no reboot needed.
+
+Total downtime: ~5 min for case open + boot. No reinstall.
+
+## Alternative paths (if M.2 install blocked)
+
+### SATA SSD/HDD (option 4 from poll)
+
+- 6 SATA ports free. Mobo has space for 2.5"/3.5" drives (case-dependent).
+- 2 TB SATA SSD ~£80, 2 TB HDD ~£25, 4 TB HDD ~£60.
+- Procedure same as NVMe but `/dev/sda` instead of `nvme1n1`.
+- HDD slower (~150 MB/s vs NVMe's 1500 MB/s) but fine for media — 4K HDR HEVC peaks at ~15 Mbps = 1.9 MB/s read.
+- Pro: cheapest per GB. Con: slower transcodes if SSD cache not configured.
+
+### USB external (option 3 from poll)
+
+- USB 3.0/3.1 ports available (at least 2× 10 Gbps slots).
+- Plug-and-play, no case open.
+- Pro: no install risk, can move drive between machines.
+- Con: cable disconnect risks media server uptime (auto-mount needs udev rule or fstab `nofail`). Slower than internal (~400-500 MB/s real-world over USB 3.1).
+- Best if: temporary expansion or testing.
+
+## Migration of `/home/user/media`
+
+Once new drive added to LVM and lv-home extended → media stays in place. NO migration needed. Just more headroom.
+
+If using a SEPARATE drive (not joining LVM):
+
+```bash
+# Mount new drive at /mnt/media-2
+sudo mkfs.ext4 /dev/nvme1n1p1   # or /dev/sda1
+sudo mkdir /mnt/media-2
+sudo mount /dev/nvme1n1p1 /mnt/media-2
+sudo chown user:user /mnt/media-2
+
+# Move TV to new drive (movies stay on /home for now)
+sudo rsync -aHAX --info=progress2 /home/user/media/tv/ /mnt/media-2/tv/
+
+# Update fstab for auto-mount on boot
+echo '/dev/nvme1n1p1 /mnt/media-2 ext4 defaults 0 2' | sudo tee -a /etc/fstab
+
+# Update Jellyfin container — stop, edit docker-compose.yml volume:
+#   /mnt/media-2/tv → /media/tv-2
+# OR just mount-bind /mnt/media-2/tv onto /home/user/media/tv (transparent to Jellyfin):
+sudo umount /home/user/media/tv  # if anything's there
+sudo rmdir /home/user/media/tv
+sudo ln -s /mnt/media-2/tv /home/user/media/tv
+```
+
+LVM-extension path is much cleaner — recommended.
+
+## Decision pending
+
+Owner picks NVMe / SATA / USB based on what's easier to get + budget. Update this doc after decision + install.
+
+## After upgrade — Rick and Morty bulk import
+
+Once `/home` has ≥ 200 GB free:
+
+```bash
+# Per playbooks/import-media/ v1.0
+# Stage all 7 seasons on onyx (already done — names need normalising)
+# rsync to nullstone in one bulk
+# Force Library/Refresh
+# Verify Series 12→13 (only 1 new — R&M existed since S01), Episodes 217→285 (+68 with all 7 seasons full)
+# Wait for S03 E06+E10 to finish download first, OR import partial + add later
+```
+
+Run logs: `playbooks/import-media/runs/rick-and-morty-s02-s08-2160p-hdr.md` (template).
