根因分析

Ollama模型拉取失败，因为本地模型缓存中缺少所需的blob文件，通常是由于下载不完整、磁盘损坏或模型存储目录的权限问题。

English

Ollama model pull fails because a required blob file is missing from the local model cache, often due to incomplete download, disk corruption, or permission issues in the model storage directory.

解决方案

  1. 删除损坏的模型并重新拉取：

ollama rm llama2
rm -rf ~/.ollama/models/blobs/sha256-*
ollama pull llama2
  2. 检查磁盘空间和权限，然后重启Ollama服务并重试：

df -h /usr/share/ollama/
sudo chown -R ollama:ollama /usr/share/ollama/.ollama
sudo systemctl restart ollama
ollama pull llama2

无效尝试

常见但无效的做法:

  1. 100% 失败

    Creates an empty file that fails integrity checks; Ollama will still error on hash verification.

  2. 50% 失败

    Changes file ownership to root, causing subsequent permission errors for non-root Ollama processes.
