不能 mkdir：磁碟配額超出，但 iNodes 和空間遠未超出

當我收到如下錯誤消息時，我正在解壓 tar 文件：

[xxxxx@lo-login-02 ~]$ tar -xvf ontonotes-release-5.0_LDC2013T19.tgz 
...... (omitted lines)
tar: ontonotes-release-5.0/tools/ontonotes-db-tool-v0.999b/src/on/__init__.py: Cannot open: No such file or directory

我檢查了我的文件系統配額、索引節點和磁碟空間，但它們似乎都很好：

[xxxxx@lo-login-02 ~]$ quota
Disk quotas for user xxxxx (uid 198587): 
    Filesystem  blocks   quota   limit   grace   files   quota   limit   grace

[xxxxx@lo-login-02 ~]$ df -i

[xxxxx@lo-login-02 ~]$ df -h

您已達到文件系統上的最大文件數，但您的使用配額。刪除一些文件（任何大小），將能夠創建新文件。
