Error writing to file

Error message

Error writing to file: {}

What it means

Raised while persisting a downloaded chunk: writer.write_all(&chunk) on the partial model file failed. The tokio file writer could not write to disk - the volume is full, the models directory was removed, or the file became unwritable (permissions, antivirus lock) while the download was running.

Solutions

1. Free disk space (or relocate the models directory) so free bytes exceed the model size listed in the catalog, then retry - the download resumes from the partial file
2. Check write permissions on the models directory (~/Library/Application Support/Meetily/models/summary on macOS, %APPDATA%\Meetily\models\summary on Windows)
3. Exclude the models directory from real-time antivirus scanning and retry
4. Delete the partial file and start a fresh download if resume keeps failing

// Before download_model: require free space >= expected model size (from the catalog)
let model = get_model_by_name(model_name).unwrap();
let free = fs2::available_space(&models_dir)?;
if free < model.size_bytes + 256 * 1024 * 1024 {
    return Err(anyhow!("insufficient disk: need {} bytes, have {}", model.size_bytes, free));
}

try {
    manager.download_model(name).await?;
} catch (e) {
    if e.to_string().contains("Error writing to file") {
        // disk/permissions problem - do NOT blind-retry; surface to user for cleanup
        return Err(anyhow!("disk write failed: free space or check permissions"));
    }
    return Err(e);
}

When it happens

Trigger: download_model is mid-stream and the target volume runs out of space (GGUF models are hundreds of MB to several GB), the models directory is deleted by an external process mid-download, or the partial file is locked by security software on Windows during write_all.

Common situations: Insufficient disk space for large LLM models, AppData/Application Support on a full drive, macOS/Windows disk quotas, antivirus quarantining or holding the partially written .gguf file.
