OpenCode nuked my storage (318 GB added) #9290
Description
Description
I asked claude to investigate and here's the report:
Summary
Opencode's snapshot system has consumed 318GB of disk space by:
- Tracking the entire home directory as a git worktree
- Leaving orphaned temp pack files with no garbage collection
Storage Breakdown
| Type | Size | Files | Description |
|---|---|---|---|
| Orphaned temp packs | 284 GB | 6 | Failed/interrupted pack operations, never cleaned |
| Loose git objects | 34 GB | 590,600 | Actual snapshot data |
| Total | 318 GB | — | For a CLI tool with no storage settings |
Orphaned Files
| File | Size | Date |
|---|---|---|
tmp_pack_qM0CSW |
108 GB | Dec 31 |
tmp_pack_Latw37 |
61 GB | Dec 31 |
tmp_pack_Tt4SKV |
54 GB | Dec 31 |
tmp_pack_nuK5V1 |
27 GB | Dec 31 |
tmp_pack_vSc9OC |
25 GB | Jan 9 |
tmp_pack_hJO3AO |
7.8 GB | Jan 1 |
$ git count-objects -vH
size-garbage: 283.84 GiB
Issues
- No cleanup mechanism — no git gc, no pruning, no temp file cleanup
- No storage limits — grows unbounded
- No user visibility — no warnings, no settings, no documentation
- Tracks entire home directory — not just project folders
Workaround
rm -rf ~/.local/share/opencode/snapshot/
Expected
- Track project directories only, not $HOME
- Clean up temp files on startup
- Run periodic garbage collection
- Implement storage limits
- Warn users or expose settings

This issue might be a duplicate of existing issues. Please check:
All these issues describe the same root cause: orphaned temp_pack files and lack of garbage collection/storage limits in the snapshot system.
Feel free to ignore if your specific case differs from these.

will auto cleanup snapshot things older than 7 days
miguelnavarro89 commentedon Jan 20, 2026
hey folks, did you guys release the fix? I don't see this changes on 1.1.28. Now, you guys set 7 days for auto cleanup but opencode currently just need 24h and disk is blown up by this issue, a big deal.
Is there a way to disable snapshots altogether?
Opencode is basically almost useless that way.

same here, snapshot 30+GB, even though source repo is only 50MB
ThePhilosopha commentedon Feb 22, 2026
Same. Mine ballooned to 40gb. I deleted it. Ran opencode cli again and it readded it.

You may can set
"snapshot": falseas a workaround.joeyism commentedon Mar 6, 2026
I had to manually
rm -rf ~/.local/share/opencode/storage
