Ollama Filled My Disk: How I Moved the Models Directory Safely
Ollama stores every model on the system drive by default. The exact steps I used to move ~/.ollama/models to a second drive on Linux, Windows and macOS without re-downloading.
Ollama Filled My Disk: How I Moved the Models Directory Safely
Eleven models later my 512 GB system drive had 9 GB free and Windows started complaining. Ollama does not warn you: it writes everything to ~/.ollama/models on the boot volume. Moving it takes five minutes and zero re-downloads.
Step 1 — See what you are actually storing

ollama list
du -sh ~/.ollama/models
ollama rm llama2:13b # models I had not touched in monthsI recovered 46 GB before moving anything. Old experiments are the cheapest win.
Step 2 — Linux / WSL2

sudo systemctl stop ollama
sudo mkdir -p /mnt/data/ollama-models
sudo rsync -a --info=progress2 ~/.ollama/models/ /mnt/data/ollama-models/
sudo chown -R ollama:ollama /mnt/data/ollama-modelssudo systemctl edit ollama
[Service]
Environment="OLLAMA_MODELS=/mnt/data/ollama-models"
sudo systemctl daemon-reload && sudo systemctl start ollama ollama list # verify BEFORE deleting the original rm -rf ~/.ollama/models
The chown line matters: the daemon runs as the ollama user and silently re-downloads everything if it cannot read the directory. That happened to me on the first attempt.

Move the folder, then set a user environment variable:
robocopy "$env:USERPROFILE\.ollama\models" "D:\ollama-models" /E /MOVE
[Environment]::SetEnvironmentVariable("OLLAMA_MODELS","D:\ollama-models","User")Quit Ollama from the tray icon and reopen — restarting the app is not optional, the variable is read at startup.
Step 4 — macOS

launchctl setenv OLLAMA_MODELS "/Volumes/External/ollama-models"External SSD caveat from my Mac mini: if the drive is not mounted at login, Ollama creates an empty directory and shows zero models. Internal storage or an always-connected Thunderbolt SSD only.

| Path | Contents | Size |
|---|---|---|
/mnt/data/ollama-models | 6 active models | 61 GB |
| system drive | Ollama binary only | < 1 GB |
Rule I now follow: keep at most six models, one per job. Storage discipline beats a bigger disk.

Will this break existing models? No. Blobs are content-addressed; a plain copy is enough as long as permissions are right.
Can I put models on a network share? Technically yes, in practice load times were awful over gigabit. Local SSD only.
A download died from lack of space — what now? Clear the partial blob first, as described in fixing Ollama pull errors. Model sizing guidance is in the local LLM guide and the ultimate AI tools guide.

After all of the above, the setup that actually held up is the one described in this guide to “Ollama Filled My Disk: How I Moved the Models Directory Safely”. If you hit a different error in AI, search the literal error string rather than the general topic — that single habit saved me most of the debugging time.
